Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of the Company, including all majority and wholly-owned subsidiaries and entities in which a controlling interest is maintained. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current year presentation. A non-controlling interest in a subsidiary reflects an ownership interest in a majority-owned subsidiary that is not attributable to the Company. For the periods presented, the Company's financial statements include a redeemable non-controlling interest (“RNCI”), which has been reported in temporary equity in the consolidated balance sheets. The net loss attributable to the RNCI is presented as an adjustment to the Company's consolidated net loss to arrive at net loss attributable to 3D Systems Corporation in the consolidated statements of operations and consolidated statements of comprehensive loss. Furthermore, adjustments to record the RNCI at its redemption value are recorded to additional paid-in capital, and the excess redemption value is recognized as an increase to net loss attributable to 3D Systems’ shareholders for purposes of reporting loss per share. See Note 15 for a summary of the activity related to the reported RNCI balance during the periods presented. Our annual reporting period is the calendar year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect (1) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet dates and (2) the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience, currently available information and various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from these estimates.
Revenue Recognition	Revenue Recognition We account for revenue in accordance with Accounting Standards Codification ("ASC") Topic 606, “Revenue from Contracts with Customers.” Collaboration arrangement contracts, for which the collaboration partner meets the definition of a customer, are recorded in accordance with ASC Topic 606; otherwise, the collaboration arrangements are recorded in accordance with ASC Topic 808, "Collaborative Arrangements." Revenue Recognition Revenue is recognized when control of the promised products or services is transferred to customers. Revenue is recognized in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and, accordingly, are accounted for as separate performance obligations. For such arrangements, we allocate revenue to each performance obligation based upon its relative stand-alone selling price (“SSP”). Revenue is recognized net of allowances for returns and any taxes collected from customers that are subsequently remitted to governmental authorities. The amount of consideration received and revenue recognized may vary based on changes in marketing incentive programs offered to our customers. Our marketing incentive programs take many forms, including volume discounts, trade-in allowances, rebates and other discounts. Refer to "Variable Consideration" section below for further discussion around the significant judgments in these areas. A majority of our revenue is recognized at the point in time when products are shipped to or services are performed for customers. However, we also enter into service contracts and collaboration agreements with customers, for which we typically are required to recognize revenue over time. Hardware and Materials Revenue from hardware and material sales is recognized when control has transferred to the customer, which generally occurs when the goods have been shipped or delivered to the customer, risk of loss has transferred to the customer, and we have a present right to payment. In limited circumstances, when printer or other hardware sales include substantive customer acceptance provisions, revenue is recognized either when customer acceptance has been obtained, customer acceptance provisions have lapsed, or we have objective evidence that the criteria specified in the customer acceptance provisions have been satisfied. Printers and certain other products include an assurance warranty for periods up to one year to ensure the product works as expected. These assurance warranties are not a separate performance obligation. For these initial product warranties, estimated costs are accrued at the time of the sale of the product. These cost estimates are established using historical information regarding the nature, frequency and average cost of claims for each type of printer or other product, as well as assumptions about future activity and events. Revisions to expense accruals are made as necessary based on changes in these historical and future factors. Software We also market and sell software tools that enable our customers to capture and customize content using our printers, design optimization and simulation software, and reverse engineering and inspection software. Our software does not require significant modification or customization, and the license provides the customer with a right to use the software as it exists when made available. Revenue from these software licenses is recognized either upon delivery of the product or of a key code which allows the customer to download the software. Customers may purchase post-sale support. Generally, the first year of support is included, but subsequent years are optional. Post-sale support, including the first year of support and the optional, subsequent years, are considered a separate obligation from the software and revenue is deferred at the time of sale and subsequently recognized ratably over future periods. Services We offer training, installation and non-contract maintenance services for our products. Additionally, we offer maintenance contracts customers can purchase at their option. For maintenance contracts, revenue is deferred at the time of sale based on the stand-alone selling prices of these services. Deferred revenue is recognized ratably over the term of the maintenance period on a straight-line basis and costs are expensed as incurred. Revenue from training, installation and non-contract maintenance services is recognized at the time of performance of the service. We also sell software as a service, whereby the customer has the right to access the software. Revenue is recognized ratably over the related subscription period, as our performance obligation to provide access to the software is progressively fulfilled over the stated term of the contract. Healthcare Solutions service sales are included within services revenue, and revenue is recognized upon shipment or delivery of the parts or performance of the service, based on the terms of the arrangement. Collaboration and Licensing Agreements We enter into collaboration and licensing arrangements with third parties. The nature of the activities to be performed and the consideration exchanged under these arrangements varies on a contract-by-contract basis. We evaluate these arrangements to determine whether they meet the definition of a customer relationship for which revenue should be recorded and recognized. These contracts may contain multiple performance obligations and may contain fees for licensing, research and development services, contingent milestone payments upon the achievement of contractual developmental criteria and/or royalty fees based on the licensees’ product revenue. We determine the revenue to be recognized under these arrangements based upon an evaluation of the distinct performance obligations; the identification and evaluation of material rights; the estimation of the amount of variable consideration to be included in transaction price, as well as the timing for inclusion of such variable consideration; and the amount of transaction price assigned to and the pattern of transfer of control for each distinct performance obligation. This typically results in the recognition of revenue over time using a cost-to-cost percentage of completion model to measure the progress of the transfer of control. Terms of Sale Shipping and handling activities are treated as fulfillment costs rather than as an additional promised service. We accrue the costs of shipping and handling when the related revenue is recognized. Our incurred costs associated with shipping and handling are included in product cost of sales. Creditworthiness is determined, and credit is extended, based upon an evaluation of each customer’s financial condition. New customers are generally required to complete a credit application and provide references and bank information to facilitate an analysis of creditworthiness. Our terms of sale generally provide payment terms that are customary in the countries where we transact business. To reduce credit risk in connection with certain sales, we may, depending upon the circumstances, require significant deposits or payment in full prior to shipment. For maintenance services, we either bill customers on a time-and-materials basis or sell maintenance contracts that provide for payment in advance on either an annual or other periodic basis. Significant Judgments Allocation of Transaction Price Our contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, we allocate revenue to each performance obligation based on its relative SSP. Judgment is required to determine the SSP for each distinct performance obligation in a contract. We estimate SSP using historical transaction data of observable prices. We use a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In other instances where SSP is not directly observable, such as when the product or service is not sold separately, we determine the SSP using information that may include market conditions, expected cost plus margin, and other observable inputs. In some circumstances, we have more than one SSP for individual products and services due to the stratification of those products and services by customers, geographic region or other factors. In these instances, we may use information such as the size of the customer and geographic region in determining the SSP. The determination of SSP is an ongoing process, and information is reviewed regularly in order to ensure SSP reflects the most current information or trends. Variable Consideration We must assess if and when it is appropriate to include variable consideration when determining transaction price. This assessment, which impacts the timing and the amount of revenue recognized under contracts accounted for in accordance with ASC 606, requires management to conclude that it is probable that a significant reversal of the amount of cumulative revenue recognized with respect to a contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. As discussed above, our collaboration and licensing agreements include our most significant variable consideration and require judgement in the estimation of the amount of variable consideration to be included in the transaction price, as well as the timing for inclusion of such variable consideration. In addition, the nature of our sales and marketing incentives may lead to consideration that is variable in the form of discounts based on volumes purchased, trade in allowances, rebates or other discounts. We estimate variable consideration based on the expected value approach, which requires judgement in the identification of possible outcomes and in assessing the probability of those outcomes, or the most likely amount approach, which requires judgement to identify the most likely amount in a range of amounts. After estimating the amount of variable consideration, the Company includes the estimated variable consideration in transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company assesses both the likelihood of a future reversal of revenue and how significant the reversal is relative to the total consideration. Our estimates are based on historical experience, contract terms and other factors. Ongoing assessments are performed to determine if updates are needed to the original estimates. Contracts Recognized Over Time The Company recognizes the revenue attributable to certain contracts over time using a cost-to-cost percentage of completion model to measure progress of the transfer of control to the customer as services are performed, for which management believes the use of costs incurred reliably depicts the measurement of progress achieved by the Company in satisfying the performance obligation because it best depicts the transfer of control to the customer as we incur costs on our contracts. The application of this accounting requires the Company to estimate total costs that will be required to satisfy the related performance obligations. These estimates could change over the term of a contract. Contract Balances The timing of revenue recognition, billings and cash collections results in the recognition of billed accounts receivable and contract assets (including unbilled receivables) and customer deposits and deferred revenue (contract liabilities) on our consolidated balance sheets. Timing of revenue recognition may differ from the timing of invoicing to customers. We record accounts receivable when we have an unconditional right to recognize revenue at the time of invoicing, and unbilled receivables when revenue is recognized prior to invoicing. For most of our contracts, customers are invoiced when products are shipped or when services are performed resulting in billed accounts receivables for the remainder of the owed contract price. Unbilled receivables generally result from circumstances in which items have been shipped, revenue has been recognized, but the customer has not been charged. We also recognize a contract asset upon the recognition of revenue related to certain performance milestones that are deemed probable of achievement, but for which billing has not occurred and receipt of payment is conditioned upon factors other than the passage of time. Some contracts require the customer to remit a large payment at or near contract inception as a deposit prior to production, which is recorded as a customer deposit liability, however, revenue is not recorded until the performance obligation is satisfied. We also typically bill in advance for installation, training and maintenance contracts, as well as for extended warranties, resulting in deferred revenue. The decrease in the contract assets balance as of December 31, 2024 (see table below) primarily relates to the decrease in the estimated variable consideration included in the transaction price related to one of the Company's collaboration and licensing agreements which has resulted in the reversal of incremental revenue for the year ending December 31, 2024 (refer to the discussion above of Collaboration and Licensing Agreements for further details) Changes in contract asset and liability balances were not materially impacted by any other factors for the years ended December 31, 2024 and 2023, respectively.
Held for Sale	Held for Sale The Company classifies assets and liabilities to be sold ("disposal group") as held for sale in the period when all of the applicable criteria are met, including: (i) management, having the authority to approve the action, commits to a plan to sell, (ii) the disposal group is available to sell in its present condition, (iii) there is an active program to locate a buyer, (iv) the disposal group is being actively marketed at a reasonable price in relation to its fair value, (v) significant changes to the plan to sell are unlikely, and (vi) the sale of the disposal group is generally probable of being completed within one year. Management performs an assessment at least quarterly, or when events or changes in business circumstances indicate that a change in classification may be necessary. Assets and liabilities identified as held for sale are presented separately within the consolidated balance sheets, with adjustments made, if necessary, to measure the disposal group at the lower of its carrying value or fair value less costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Gains on the sale of a disposal group are not recognized until the date of sale. Depreciation of property, plant and equipment and amortization of intangible and right-of-use assets are not recorded while these assets are classified as held for sale. For each period that a disposal group remains classified as held for sale, its recoverability is reassessed and any necessary adjustments are made to its carrying value. Gains or losses recognized upon the sale of a disposal group that does not qualify as a discontinued operation are included in loss from operations in the consolidated statements of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with maturities of three months or less when acquired. At times, cash and cash equivalents balances may be in excess of FDIC insurance limits.
Short-Term Investments / Investments and Notes Receivable	Short-Term Investments At times, the Company has invested a portion of its excess cash in short-term investments. The Company's short-term investment accounting policy is that securities with maturities greater than 90 days at the time of purchase that are available for operations in the next 12 months are classified as short-term investments. The Company’s short-term investments typically have consisted of investment grade bonds, certificates of deposit, commercial paper, and short maturity bond funds, all with a remaining maturity of generally less than twelve months at the date of purchase and classified as available-for-sale. Interest and dividends on these investments are recorded as income when earned. Available-for-sale securities, which consist of debt securities, are carried at fair value with unrealized gains and losses, net of related tax, reported in accumulated other comprehensive loss. Adjustments to the fair value of investments classified as available-for-sale are recorded as an increase or decrease in accumulated other comprehensive income (loss) in shareholders’ equity. Impairment of available-for-sale securities that is attributable to credit losses is recognized as an allowance for credit losses in the consolidated statement of operations in the period in which a credit loss is identified. The Company periodically evaluates its investments for credit losses. Investments and Notes Receivable The aggregate carrying values of our investments totaled $27.7 million and $26.8 million at December 31, 2024 and 2023, respectively. At each balance sheet date, these investments consist of equity securities without a readily determinable fair value, equity securities accounted for in accordance with the equity method of accounting, and a note receivable balance. Our accounting policies for each classification of investments are as follows. Investments in Equity Securities with a Readily Determinable Fair Value Upon making an initial investment in an equity security, we assess whether the equity security has a readily determinable fair value. For investments that meet the definition of and, therefore, qualify to be accounted for as an equity security without a readily determinable fair value, we subsequently reassess whether they continue to meet the definition of an equity security without a readily determinable fair value on a quarterly basis. We recognize investments in equity securities without a readily determinable fair value at cost, minus impairment. In addition, we are required to remeasure the carrying value of an investment in equity securities without a readily determinable fair value if we identify observable price changes that relate to orderly transactions for an identical or similar investment in the same issuer. The remeasurement of the carrying value of an investment due to an identified observable price change shall be based upon the investment's fair value as of the date that the observable transaction occurred. Remeasurements, whether the result of impairment or observable price changes attributable to orderly transactions, are recorded as an adjustment to our reported net income or net loss. We assess our investments in equity securities without a readily determinable fair value for potential impairment upon the occurrence of an event or a change in circumstances that would indicate the carrying amount of an investment may be impaired. On a quarterly basis, we first perform a qualitative assessment for potential impairment to determine whether measurement of the fair value of an investment to further assess for impairment is required. Impairments of equity securities without a readily determinable fair value are recorded to other income (loss), net in our consolidated statements of operations in the period in which they become impaired.
Variable Interest Entities	Variable Interest Entities Upon making an investment in an entity, we assess whether the entity is a variable interest entity ("VIE"). The determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk at the time of our investment is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary. We may be required to reassess our conclusion as to whether an entity in which we have made an investment is a VIE upon the occurrence of a reconsideration event – for example, the occurrence of an event that may impact and, accordingly, requires a reassessment of whether an entity's total equity investment at risk is sufficient to finance the entity's activities without additional subordinated financial support. We analyze any investments in VIEs to determine whether we are the primary beneficiary. We perform this assessment at the time that we become involved with a VIE and continuously reassess whether circumstances indicate that there might be a change in our conclusion regarding whether we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we consider both our direct and indirect economic interests in the entity. Determining which reporting entity, if any, is the primary beneficiary of a VIE is primarily a qualitative approach focused on identifying which reporting entity has both (1) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. This analysis requires the exercise of judgment. We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact a VIE’s economic performance including, but not limited to, the ability to direct a VIE’s operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions. We have concluded that our investments in Theradaptive, Enhatch and the National Additive Manufacturing Innovation ("NAMI") joint venture are each an investment in a VIE. These entities are not consolidated because we have further concluded that the Company is not the primary beneficiary.
Equity Method of Accounting	Equity Method of Accounting The Company accounts for its investments in the common stock of NAMI and Enhatch using the equity method of accounting because it does not have a controlling interest and is not the primary beneficiary of these VIEs; however, the Company has the ability to exert significant influence. The Company's investments in NAMI's common stock were initially recorded at cost; whereas, the Company's investment in Enhatch's common stock, which reflects the partial exercise of a warrant, was recorded at the fair value of the common stock that was received upon exercise of the warrant. Each of these investments is subsequently adjusted for the Company’s proportionate share of the net earnings or losses and the other comprehensive income or loss of the investee. Intra-entity profits or losses associated with each equity method investment are eliminated until realized by the investee or the Company in transactions with third parties. Income or loss from these equity method investments is recorded as a separate line item in the consolidated statements of operations on a three-month lag. We evaluate material events occurring during the three-month lag period to determine whether the effects of such events should be disclosed in our financial statements. The Company evaluates each investment for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.
Notes Receivable	Notes Receivable During December 2024, the Company entered into a short-term, non-interest bearing loan agreement with NAMI, whereby NAMI borrowed $2.0 million to finance its working capital and capital expenditure requirements. The related party loan is accounted for at amortized cost and included in prepaid expenses and other current assets on our consolidated balance sheet. During the year ended December 31, 2024, the Company recorded a $0.5 million charge to other income (loss), net in our consolidated statements of operations as a result of concluding that the note receivable outstanding as of December 31, 2023 was not collectible.
Accounts Receivable and Allowances for Credit Losses	Accounts Receivable and Allowance for Credit Losses Trade accounts receivable are recorded at the invoiced amount and do not bear interest. In evaluating the collectability of accounts receivable, we assess a number of factors, including specific customers’ ability to meet their financial obligations to us, the length of time receivables are past due, historical collection experience, current economic conditions, and reasonable and supportable forecasts. Based on these assessments, we record and adjust reserves for accounts receivable balances due from specific customers, as well as establish an allowance for expected credit losses related to our accounts receivable as a whole. If circumstances related to specific customers change, or economic conditions deteriorate such that our past collection experience is no longer relevant, our estimate of the recoverability of accounts receivable could be further reduced from the levels provided for in the consolidated financial statements. As of December 31, 2024 and 2023, no single customer represented more than 10% of our consolidated accounts receivable balance.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value, with cost reflecting standard cost, which approximates the first-in, first-out method. Capitalized inventory costs include materials, labor, and manufacturing overhead that relate to the acquisition of raw materials and production into finished goods. The Company regularly reviews inventory for excess and obsolescence and records a provision to write down inventory to its net realizable value when carrying value is in excess of such value.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the determination of net income or loss. Repairs and maintenance costs are expensed as incurred.
Intangible Assets (Excluding Goodwill)	Intangible Assets (Excluding Goodwill) Intangible assets include patents, trade names, customer relationships, acquired technology, and in process research and development ("IPR&D"). Intangible assets with a finite life are (1) amortized on a straight-line basis, with estimated useful lives typically ranging from 2 to 20 years, and (2) assessed for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable, consistent with the Company's accounting policy for other long-lived assets with a finite life. Amortization expense is generally recognized within selling, general and administrative expense on the consolidated statements of operations. Acquired IPR&D represents the fair value assigned to those research and development ("R&D") projects that were acquired in a business combination for which the related products have not received regulatory approval or commercial viability and have no alternative future use. If the project is not completed or is terminated or abandoned, the Company may have to recognize an impairment related to the IPR&D, which is charged to expense.
Goodwill	Goodwill Goodwill is the excess of the cost of an acquired entity over the amounts assigned to the assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually, and is tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Impairment testing for goodwill is performed at the reporting unit level, with all goodwill assigned to a reporting unit. During the fourth quarter of 2023, we elected to change the annual goodwill impairment testing date for each of our reporting units from November 30th to November 1st. The Company does not believe that this change to the annual impairment testing date represents a material change in the method of applying an accounting principle. This voluntary change is preferable because it provides management with sufficient time to complete goodwill impairment tests in advance of the Company’s year-end financial reporting and provides additional time for the execution of key controls and management review over the significant estimates and judgements inherent in the performance of the test. This change to the goodwill impairment testing date was not applied retrospectively as it was impracticable to do so without applying hindsight when developing key assumptions and estimates required to perform the test. The testing of goodwill for impairment requires the Company to make several estimates related to projected future cash flows to determine the fair value of the reporting units to which goodwill has been assigned. The Company determines whether each reporting unit's fair value exceeds its carrying amount, including goodwill, based upon projections of future revenues, expenses, and cash flows discounted to their present value, as well as the application of a market approach. Internal operational budgets and long-range strategic plans are used as a basis for the cash flow analysis. The Company also utilizes assumptions related to working capital, capital expenditures, and terminal growth rates. The discount rate applied to the cash flow analysis is based on the weighted average cost of capital (“WACC”) for each reporting unit. These valuation approaches require the application of Level 3 valuation inputs (as defined in Note 23). An impairment is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit.
Long Lived Assets Impairment	Long Lived Assets Impairment We review long-lived assets ("asset groups") that are held and used for impairment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be recoverable. The carrying value of an asset group that is held and used is not recoverable if it exceeds the sum of the undiscounted cash flows that are expected to result from the asset group's use and eventual disposition. If we determine that an asset group's carrying value is not recoverable, we must then compare the asset group's carrying value to its estimated fair value and record any excess carrying value over fair value as an impairment loss. Any impairment loss that is recognized is required to be allocated to the long-lived assets of an asset group on a pro rata basis, using the relative carrying amounts of the long-lived assets comprising the asset group, except that the loss allocated to an individual long-lived asset shall not reduce its carrying amount below its fair value whenever that fair value is determinable without undue cost and effort. During the three months ended September 30, 2024, the Company concluded that there were indicators that the primary asset group underlying the Company's core operations should be tested for recoverability based upon the reporting of losses and negative cash flows for both current and historical reporting periods, combined with the significant decline in the Company's stock price during the period. Upon assessing this asset group for recoverability, the Company concluded that the asset group's carrying value exceeded the undiscounted cash flows that the asset group was expected to generate over the estimated remaining useful life of the asset group's primary asset, which was deemed to be acquired technology. Accordingly, the Company further tested this asset group for impairment as of September 30, 2024, using projected discounted cash flows, as well as a market approach based upon revenue multiples, to estimate the asset group's fair value.
Contingencies	Contingencies We follow the provisions of ASC 450, “Contingencies,” which requires that an estimated loss from a loss contingency be accrued by a charge to income if (1) it is probable that an asset has been impaired or that a liability has been incurred and (2) the amount of the loss can be reasonably estimated. Legal costs related to the defense or settlement of a loss contingency are expensed when such costs are incurred and, accordingly, future legal costs expected to be incurred are not accrued as part of the liability recorded when a loss contingency has been deemed probable and estimable.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions The local currency in which a subsidiary operates is generally considered its functional currency for those subsidiaries domiciled outside the United States ("foreign subsidiaries"). The functional currency financial statements of foreign subsidiaries are translated to U.S. dollars ("USD") in connection with the preparation of the Company's consolidated financial statements. Assets and liabilities of foreign subsidiaries are translated to USD at month-end exchange rates applicable to the reporting period. Income and expense items are translated to USD monthly using monthly average exchange rates. The effects of translating a foreign subsidiary's financial statements are recorded as currency translation adjustments and reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity. Foreign currency transactions are those transactions whose terms are denominated in a currency other than an entity's functional currency. Foreign currency transactions that remain unsettled as of the end of a reporting period must be remeasured into the entity's functional currency, resulting in the recognition of a gain or loss when a change in exchange rate has occurred subsequent to the date on which the transaction was originally recognized or was most recently remeasured. The Company recognizes foreign currency transaction gains and losses within foreign exchange gain (loss), net on its consolidated statements of operations.
Research and Development Costs	Research and Development Costs R&D costs, consisting primarily of employee compensation, operating supplies, facility costs and depreciation, are expensed as incurred. When the Company is reimbursed by a collaboration partner for work the Company performs, it records the costs incurred as R&D expense and the related reimbursement as a reduction to R&D expense in its consolidated statements of operations.
Earnings Per Share and Net Loss Per Share	Earnings Per Share and Net Loss Per Share Basic earnings per share and basic net loss per share are calculated using the weighted-average number of common shares outstanding during each period. When applicable, diluted earnings per share is calculated based upon the inclusion of additional dilutive and potentially dilutive shares, which include shares issuable upon the exercise of outstanding stock options, upon the vesting of employee restricted stock-based awards, for settlement of accrued incentive compensation to be paid in shares (if and when related performance-based conditions have been satisfied as of the end of the reporting period), and to settle the portion of the convertible notes that may be settled in shares (where the conversion of such instruments would be dilutive).
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and recorded in selling, general and administrative expense.
Pension Costs	Pension Costs We sponsor a retirement benefit for one of our non-U.S. subsidiaries in the form of a defined benefit pension plan. Accounting standards require the cost of providing this pension benefit to be measured on an actuarial basis. The application of these accounting standards require us to make assumptions and judgements that can significantly affect the measurement of our pension expense and our pension liability. Actuarial gains and losses resulting from both normal year-to-year changes in valuation assumptions and differences between assumptions and actual experience are deferred and amortized. Our critical assumptions in performing these actuarial valuations include the selections of the rate of compensation increase and the discount rate used to determine the present value of the pension obligations, each of which affects the amount of pension expense and pension liability recorded in any given period. Changes in the rate of compensation increase or discount rate could have a material effect on our reported pension obligations and related pension expense.
Equity Compensation Plans	Equity Compensation Plans We recognize compensation expense for our stock-based compensation programs, which provide for the issuance of stock options, restricted stock, restricted stock units (“RSU”), performance-based awards and market-based awards. The fair value of service-based awards is estimated at the grant date and recognized as expense ratably over the requisite service period of the award. The fair value of performance-based awards is estimated on the grant date and expensed over an implicit or explicit service period when the performance condition is deemed probable of achievement. Performance-based awards that cliff vest are expensed ratably using the straight-line method; whereas, performance-based awards with graded vesting features are expensed using the graded vesting method. Stock compensation expense recorded for performance-based awards is reversed if the performance condition is no longer deemed probable of achievement or ultimately is not met. Some RSUs are granted with a performance measure derived from non-GAAP-based management targets or non-financial targets. Depending on our performance with respect to these metrics, the number of RSUs earned may be less than, equal to or greater than the original number of RSUs awarded, subject to a payout range. The fair value of awards with market conditions ("market-based awards") is determined using a Monte Carlo valuation model and is expensed over an implicit or explicit service period regardless of whether the market condition is probable of achievement or not. Market-based awards that cliff vest are expensed ratably using the straight-line method; whereas, market-based awards with graded vesting features are expensed using the graded vesting method. Stock compensation expense is not reversed if the market condition is not met. For all share-based payment awards, we recognize forfeitures when they occur.
Income Taxes	Income Taxes We and the majority of our domestic subsidiaries file a consolidated U.S. federal income tax return, while four of our domestic entities file separate U.S. federal income tax returns. Our non-U.S. subsidiaries file income tax returns in their respective jurisdictions. Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for tax benefit carryforwards. Our deferred income tax assets and liabilities at the end of each period are determined using enacted tax rates. We establish a valuation allowance for those jurisdictions in which the expiration date of tax benefit carryforwards or projected taxable earnings leads us to conclude that it is “more likely than not” that a deferred tax asset will not be realized. This evaluation process includes the consideration of all available evidence regarding historical results and future projections, including the estimated timing of reversals of existing taxable temporary differences and potential tax planning strategies. Once a valuation allowance is established, it is maintained until a change in factual circumstances gives rise to sufficient income of the appropriate character and timing that will allow a partial or full utilization of the deferred tax asset. In accordance with ASC 740, “Income Taxes,” the impact of an uncertain tax position on our income tax returns is recognized at the largest amount that is more likely than not to be required to be recognized upon audit by the relevant taxing authority. We include interest and penalties accrued in the consolidated financial statements as a component of income tax expense.
Operating and Finance Leases	Operating and Finance Leases We determine if an arrangement contains a lease at inception. We record both operating leases and finance leases on our balance sheet and do not separate non-lease components from our real estate leases. We exclude leases with a term of one year or less at the commencement date from our consolidated balance sheets. Some leases include the option to purchase the leased asset, terminate the lease or extend the lease for one or more years. These options are considered in the determination of the estimated lease term when it is reasonably certain that an option will be exercised. Our leases do not contain any material residual value guarantees or material restrictive covenants. Most of our leases do not provide an implicit rate; therefore, we use our incremental borrowing rate based on information available at the lease commencement date to determine the present value of the future lease payments. Certain of our leases include variable costs. Variable costs include non-lease components that are incurred based upon actual terms, rather than contractually fixed amounts. In addition, variable costs are incurred for lease payments that are indexed to a change in rate or index. Because the right-of-use ("ROU") assets recorded on the balance sheet are determined based upon factors considered at the lease commencement date, subsequent changes in the rate or index that were not contemplated in the ROU asset balances at lease commencement result in variable expenses being recorded when these expenses are incurred during the lease term.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments," related to induced conversions of convertible debt instruments. The amendments in this ASU clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU permit an entity to apply the new guidance on either a prospective or retrospective basis. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses." The amendments in this ASU require public entities to provide disaggregated disclosure of expenses included within relevant income statement expense captions, as well as additional disclosures about selling expenses. This update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments in this ASU should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of the ASU or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements. In March 2024, the FASB issued ASU 2024-02, "Codification Improvements - Amendments to Remove References to the Concepts Statements" (“ASU 2024-02”). This guidance is intended to remove references to various FASB Concepts Statements. The Board has a standing project on its agenda to address suggestions received from stakeholders on the Accounting Standards Codification and other incremental improvements to U.S. GAAP. This effort facilitates Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The resulting amendments are referred to as Codification improvements. The amendments in ASU 2024-02 are not intended to result in significant accounting change for most entities. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements. In March 2024, the FASB issued ASU 2024-01, "Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards" (“ASU 2024-01”). This guidance is intended to improve U.S. GAAP. by adding an illustrative example to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether profits interest and similar awards (“profits interest awards”) should be accounted for in accordance with Topic 718, Compensation - Stock Compensation. The amendments in ASU 2024-01 are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. The amendments in ASU 2024-01 should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, while permitted to be adopted on a retrospective basis. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. Upon adoption, this ASU is expected to result in the inclusion of additional tax-related disclosures in the footnotes to our consolidated financial statements. Recently Adopted Accounting Standards In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures." This ASU expands upon existing reportable segment disclosure requirements by requiring the disclosure of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss, as well as conforming interim period disclosures with annual period disclosures. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this standard in the fourth quarter of our fiscal year ending December 31, 2024. Refer to Note 21 for our updated presentation and disclosures. The Company retrospectively applied the updated presentation and disclosures to all prior periods presented. Adoption of this ASU did not have an impact on the Company's results of operations, cash flows or financial position. No other new accounting pronouncements issued or effective during the periods reflected in our consolidated statements of operations have had or are expected to have a significant impact on our consolidated financial statements.
Fair Value Measurements	Assets and Liabilities Measured at Fair Value on a Recurring Basis Cash equivalents are valued utilizing the market approach for measuring the fair value of financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The carrying amounts of our cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value as of December 31, 2024 and 2023 because of the relatively short duration of these instruments.

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2024

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The consolidated financial statements include the accounts of the Company, including all majority and wholly-owned subsidiaries and entities in which a controlling interest is maintained. Intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current year presentation.

A non-controlling interest in a subsidiary reflects an ownership interest in a majority-owned subsidiary that is not attributable to the Company. For the periods presented, the Company's financial statements include a redeemable non-controlling interest (“RNCI”), which has been reported in temporary equity in the consolidated balance sheets. The net loss attributable to the RNCI is presented as an adjustment to the Company's consolidated net loss to arrive at net loss attributable to 3D Systems Corporation in the consolidated statements of operations and consolidated statements of comprehensive loss. Furthermore, adjustments to record the RNCI at its redemption value are recorded to additional paid-in capital, and the excess redemption value is recognized as an increase to net loss attributable to 3D Systems’ shareholders for purposes of reporting loss per share. See Note 15 for a summary of the activity related to the reported RNCI balance during the periods presented.

Our annual reporting period is the calendar year.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect (1) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet dates and (2) the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience, currently available information and various other assumptions that we believe are reasonable under the circumstances. Actual results could differ from these estimates.

Revenue Recognition

We account for revenue in accordance with Accounting Standards Codification ("ASC") Topic 606, “Revenue from Contracts with Customers.” Collaboration arrangement contracts, for which the collaboration partner meets the definition of a customer, are recorded in accordance with ASC Topic 606; otherwise, the collaboration arrangements are recorded in accordance with ASC Topic 808, "Collaborative Arrangements."

Revenue Recognition

Revenue is recognized when control of the promised products or services is transferred to customers. Revenue is recognized in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and, accordingly, are accounted for as separate performance obligations. For such arrangements, we allocate revenue to each performance obligation based upon its relative stand-alone selling price (“SSP”). Revenue is recognized net of allowances for returns and any taxes collected from customers that are subsequently remitted to governmental authorities. The amount of consideration received and revenue recognized may vary based on changes in marketing incentive programs offered to our customers. Our marketing incentive programs take many forms, including volume discounts, trade-in allowances, rebates and other discounts. Refer to "Variable Consideration" section below for further discussion around the significant judgments in these areas.

A majority of our revenue is recognized at the point in time when products are shipped to or services are performed for customers. However, we also enter into service contracts and collaboration agreements with customers, for which we typically are required to recognize revenue over time.

Hardware and Materials

Revenue from hardware and material sales is recognized when control has transferred to the customer, which generally occurs when the goods have been shipped or delivered to the customer, risk of loss has transferred to the customer, and we have a present right to payment. In limited circumstances, when printer or other hardware sales include substantive customer acceptance provisions, revenue is recognized either when customer acceptance has been obtained, customer acceptance provisions have lapsed, or we have objective evidence that the criteria specified in the customer acceptance provisions have been satisfied.

Printers and certain other products include an assurance warranty for periods up to one year to ensure the product works as expected. These assurance warranties are not a separate performance obligation. For these initial product warranties, estimated costs are accrued at the time of the sale of the product. These cost estimates are established using historical information regarding the nature, frequency and average cost of claims for each type of printer or other product, as well as assumptions about future activity and events. Revisions to expense accruals are made as necessary based on changes in these historical and future factors.

Software

We also market and sell software tools that enable our customers to capture and customize content using our printers, design optimization and simulation software, and reverse engineering and inspection software. Our software does not require significant modification or customization, and the license provides the customer with a right to use the software as it exists when made available. Revenue from these software licenses is recognized either upon delivery of the product or of a key code which allows the customer to download the software. Customers may purchase post-sale support. Generally, the first year of support is included, but subsequent years are optional. Post-sale support, including the first year of support and the optional, subsequent years, are considered a separate obligation from the software and revenue is deferred at the time of sale and subsequently recognized ratably over future periods.

Services

We offer training, installation and non-contract maintenance services for our products. Additionally, we offer maintenance contracts customers can purchase at their option. For maintenance contracts, revenue is deferred at the time of sale based on the stand-alone selling prices of these services. Deferred revenue is recognized ratably over the term of the maintenance period on a straight-line basis and costs are expensed as incurred. Revenue from training, installation and non-contract maintenance services is recognized at the time of performance of the service.

We also sell software as a service, whereby the customer has the right to access the software. Revenue is recognized ratably over the related subscription period, as our performance obligation to provide access to the software is progressively fulfilled over the stated term of the contract.

Healthcare Solutions service sales are included within services revenue, and revenue is recognized upon shipment or delivery of the parts or performance of the service, based on the terms of the arrangement.

Collaboration and Licensing Agreements

We enter into collaboration and licensing arrangements with third parties. The nature of the activities to be performed and the consideration exchanged under these arrangements varies on a contract-by-contract basis. We evaluate these arrangements to determine whether they meet the definition of a customer relationship for which revenue should be recorded and recognized. These contracts may contain multiple performance obligations and may contain fees for licensing, research and development services, contingent milestone payments upon the achievement of contractual developmental criteria and/or royalty fees based on the licensees’ product revenue. We determine the revenue to be recognized under these arrangements based upon an evaluation of the distinct performance obligations; the identification and evaluation of material rights; the estimation of the amount of variable consideration to be included in transaction price, as well as the timing for inclusion of such variable consideration; and the amount of transaction price assigned to and the pattern of transfer of control for each distinct performance obligation. This typically results in the recognition of revenue over time using a cost-to-cost percentage of completion model to measure the progress of the transfer of control.

Terms of Sale

Shipping and handling activities are treated as fulfillment costs rather than as an additional promised service. We accrue the costs of shipping and handling when the related revenue is recognized. Our incurred costs associated with shipping and handling are included in product cost of sales.

Creditworthiness is determined, and credit is extended, based upon an evaluation of each customer’s financial condition. New customers are generally required to complete a credit application and provide references and bank information to facilitate an analysis of creditworthiness.

Our terms of sale generally provide payment terms that are customary in the countries where we transact business. To reduce credit risk in connection with certain sales, we may, depending upon the circumstances, require significant deposits or payment in full prior to shipment. For maintenance services, we either bill customers on a time-and-materials basis or sell maintenance contracts that provide for payment in advance on either an annual or other periodic basis.

Significant Judgments

Allocation of Transaction Price

Our contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, we allocate revenue to each performance obligation based on its relative SSP.

Judgment is required to determine the SSP for each distinct performance obligation in a contract. We estimate SSP using historical transaction data of observable prices. We use a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In other instances where SSP is not directly observable, such as when the product or service is not sold separately, we determine the SSP using information that may include market conditions, expected cost plus margin, and other observable inputs.

In some circumstances, we have more than one SSP for individual products and services due to the stratification of those products and services by customers, geographic region or other factors. In these instances, we may use information such as the size of the customer and geographic region in determining the SSP.

The determination of SSP is an ongoing process, and information is reviewed regularly in order to ensure SSP reflects the most current information or trends.

Variable Consideration

We must assess if and when it is appropriate to include variable consideration when determining transaction price. This assessment, which impacts the timing and the amount of revenue recognized under contracts accounted for in accordance with ASC 606, requires management to conclude that it is probable that a significant reversal of the amount of cumulative revenue recognized with respect to a contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

As discussed above, our collaboration and licensing agreements include our most significant variable consideration and require judgement in the estimation of the amount of variable consideration to be included in the transaction price, as well as the timing for inclusion of such variable consideration. In addition, the nature of our sales and marketing incentives may lead to consideration that is variable in the form of discounts based on volumes purchased, trade in allowances, rebates or other discounts. We estimate variable consideration based on the expected value approach, which requires judgement in the identification of possible outcomes and in assessing the probability of those outcomes, or the most likely amount approach, which requires judgement to identify the most likely amount in a range of amounts. After estimating the amount of variable consideration, the Company includes the estimated variable consideration in transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company assesses both the likelihood of a future reversal of revenue and how significant the reversal is relative to the total consideration. Our estimates are based on historical experience, contract terms and other factors. Ongoing assessments are performed to determine if updates are needed to the original estimates.

Contracts Recognized Over Time

The Company recognizes the revenue attributable to certain contracts over time using a cost-to-cost percentage of completion model to measure progress of the transfer of control to the customer as services are performed, for which management believes the use of costs incurred reliably depicts the measurement of progress achieved by the Company in satisfying the performance obligation because it best depicts the transfer of control to the customer as we incur costs on our contracts. The application of this accounting requires the Company to estimate total costs that will be required to satisfy the related performance obligations. These estimates could change over the term of a contract.

Contract Balances

The timing of revenue recognition, billings and cash collections results in the recognition of billed accounts receivable and contract assets (including unbilled receivables) and customer deposits and deferred revenue (contract liabilities) on our consolidated balance sheets. Timing of revenue recognition may differ from the timing of invoicing to customers. We record accounts receivable when we have an unconditional right to recognize revenue at the time of invoicing, and unbilled receivables when revenue is recognized prior to invoicing. For most of our contracts, customers are invoiced when products are shipped or when services are performed resulting in billed accounts receivables for the remainder of the owed contract price. Unbilled receivables generally result from circumstances in which items have been shipped, revenue has been recognized, but the customer has not been charged. We also recognize a contract asset upon the recognition of revenue related to certain performance milestones that are deemed probable of achievement, but for which billing has not occurred and receipt of payment is conditioned upon factors other than the passage of time. Some contracts require the customer to remit a large payment at or near contract inception as a deposit prior to production, which is recorded as a customer deposit liability, however, revenue is not recorded until the performance obligation is satisfied. We also typically bill in advance for installation, training and maintenance contracts, as well as for extended warranties, resulting in deferred revenue.

The decrease in the contract assets balance as of December 31, 2024 (see table below) primarily relates to the decrease in the estimated variable consideration included in the transaction price related to one of the Company's collaboration and licensing agreements which has resulted in the reversal of incremental revenue for the year ending December 31, 2024 (refer to the discussion above of Collaboration and Licensing Agreements for further details) Changes in contract asset and liability balances were not materially impacted by any other factors for the years ended December 31, 2024 and 2023, respectively.

Held for Sale

The Company classifies assets and liabilities to be sold ("disposal group") as held for sale in the period when all of the applicable criteria are met, including: (i) management, having the authority to approve the action, commits to a plan to sell, (ii) the disposal group is available to sell in its present condition, (iii) there is an active program to locate a buyer, (iv) the disposal group is being actively marketed at a reasonable price in relation to its fair value, (v) significant changes to the plan to sell are unlikely, and (vi) the sale of the disposal group is generally probable of being completed within one year. Management performs an assessment at least quarterly, or when events or changes in business circumstances indicate that a change in classification may be necessary. Assets and liabilities identified as held for sale are presented separately within the consolidated

balance sheets, with adjustments made, if necessary, to measure the disposal group at the lower of its carrying value or fair value less costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Gains on the sale of a disposal group are not recognized until the date of sale. Depreciation of property, plant and equipment and amortization of intangible and right-of-use assets are not recorded while these assets are classified as held for sale. For each period that a disposal group remains classified as held for sale, its recoverability is reassessed and any necessary adjustments are made to its carrying value. Gains or losses recognized upon the sale of a disposal group that does not qualify as a discontinued operation are included in loss from operations in the consolidated statements of operations.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid investments with maturities of three months or less when acquired. At times, cash and cash equivalents balances may be in excess of FDIC insurance limits.

Short-Term Investments / Investments and Notes Receivable

Short-Term Investments

At times, the Company has invested a portion of its excess cash in short-term investments. The Company's short-term investment accounting policy is that securities with maturities greater than 90 days at the time of purchase that are available for operations in the next 12 months are classified as short-term investments. The Company’s short-term investments typically have consisted of investment grade bonds, certificates of deposit, commercial paper, and short maturity bond funds, all with a remaining maturity of generally less than twelve months at the date of purchase and classified as available-for-sale. Interest and dividends on these investments are recorded as income when earned.

Available-for-sale securities, which consist of debt securities, are carried at fair value with unrealized gains and losses, net of related tax, reported in accumulated other comprehensive loss. Adjustments to the fair value of investments classified as available-for-sale are recorded as an increase or decrease in accumulated other comprehensive income (loss) in shareholders’ equity. Impairment of available-for-sale securities that is attributable to credit losses is recognized as an allowance for credit losses in the consolidated statement of operations in the period in which a credit loss is identified. The Company periodically evaluates its investments for credit losses.

Investments and Notes Receivable

The aggregate carrying values of our investments totaled $27.7 million and $26.8 million at December 31, 2024 and 2023, respectively. At each balance sheet date, these investments consist of equity securities without a readily determinable fair value, equity securities accounted for in accordance with the equity method of accounting, and a note receivable balance. Our accounting policies for each classification of investments are as follows.

Investments in Equity Securities with a Readily Determinable Fair Value

Upon making an initial investment in an equity security, we assess whether the equity security has a readily determinable fair value. For investments that meet the definition of and, therefore, qualify to be accounted for as an equity security without a readily determinable fair value, we subsequently reassess whether they continue to meet the definition of an equity security without a readily determinable fair value on a quarterly basis.

We recognize investments in equity securities without a readily determinable fair value at cost, minus impairment. In addition, we are required to remeasure the carrying value of an investment in equity securities without a readily determinable fair value if we identify observable price changes that relate to orderly transactions for an identical or similar investment in the same issuer. The remeasurement of the carrying value of an investment due to an identified observable price change shall be based upon the investment's fair value as of the date that the observable transaction occurred. Remeasurements, whether the result of impairment or observable price changes attributable to orderly transactions, are recorded as an adjustment to our reported net income or net loss.

We assess our investments in equity securities without a readily determinable fair value for potential impairment upon the occurrence of an event or a change in circumstances that would indicate the carrying amount of an investment may be impaired. On a quarterly basis, we first perform a qualitative assessment for potential impairment to determine whether measurement of the fair value of an investment to further assess for impairment is required. Impairments of equity securities without a readily determinable fair value are recorded to other income (loss), net in our consolidated statements of operations in the period in which they become impaired.

Variable Interest Entities

Upon making an investment in an entity, we assess whether the entity is a variable interest entity ("VIE"). The determination of whether an entity in which we hold a direct or indirect variable interest is a VIE is based on several factors, including whether the entity’s total equity investment at risk at the time of our investment is sufficient to finance the entity’s activities without additional subordinated financial support. We make judgments regarding the sufficiency of the equity at risk based first on a qualitative analysis, and then a quantitative analysis, if necessary. We may be required to reassess our conclusion as to whether an entity in which we have made an investment is a VIE upon the occurrence of a reconsideration event – for example, the occurrence of an event that may impact and, accordingly, requires a reassessment of whether an entity's total equity investment at risk is sufficient to finance the entity's activities without additional subordinated financial support.

We analyze any investments in VIEs to determine whether we are the primary beneficiary. We perform this assessment at the time that we become involved with a VIE and continuously reassess whether circumstances indicate that there might be a change in our conclusion regarding whether we are the primary beneficiary. In evaluating whether we are the primary beneficiary, we consider both our direct and indirect economic interests in the entity. Determining which reporting entity, if any, is the primary beneficiary of a VIE is primarily a qualitative approach focused on identifying which reporting entity has both (1) the power to direct the activities of a VIE that most significantly impact such entity’s economic performance and (2) the obligation to absorb losses or the right to receive benefits from such entity that could potentially be significant to such entity. This analysis requires the exercise of judgment. We consider a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact a VIE’s economic performance including, but not limited to, the ability to direct a VIE’s operating decisions and activities. In addition, we consider the rights of other investors to participate in those decisions.

We have concluded that our investments in Theradaptive, Enhatch and the National Additive Manufacturing Innovation ("NAMI") joint venture are each an investment in a VIE. These entities are not consolidated because we have further concluded that the Company is not the primary beneficiary.

Equity Method of Accounting

The Company accounts for its investments in the common stock of NAMI and Enhatch using the equity method of accounting because it does not have a controlling interest and is not the primary beneficiary of these VIEs; however, the Company has the ability to exert significant influence. The Company's investments in NAMI's common stock were initially recorded at cost; whereas, the Company's investment in Enhatch's common stock, which reflects the partial exercise of a warrant, was recorded at the fair value of the common stock that was received upon exercise of the warrant. Each of these investments is subsequently adjusted for the Company’s proportionate share of the net earnings or losses and the other comprehensive income or loss of the investee. Intra-entity profits or losses associated with each equity method investment are eliminated until realized by the investee or the Company in transactions with third parties. Income or loss from these equity method investments is recorded as a separate line item in the consolidated statements of operations on a three-month lag. We evaluate material events occurring during the three-month lag period to determine whether the effects of such events should be disclosed in our financial statements. The Company evaluates each investment for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

Notes Receivable

During December 2024, the Company entered into a short-term, non-interest bearing loan agreement with NAMI, whereby NAMI borrowed $2.0 million to finance its working capital and capital expenditure requirements. The related party loan is accounted for at amortized cost and included in prepaid expenses and other current assets on our consolidated balance sheet.

During the year ended December 31, 2024, the Company recorded a $0.5 million charge to other income (loss), net in our consolidated statements of operations as a result of concluding that the note receivable outstanding as of December 31, 2023 was not collectible.

Accounts Receivable and Allowances for Credit Losses

Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. In evaluating the collectability of accounts receivable, we assess a number of factors, including specific customers’ ability to meet their financial obligations to us, the length of time receivables are past due, historical collection experience, current economic conditions, and reasonable and supportable forecasts. Based on these assessments, we record and adjust reserves for accounts receivable balances due from specific customers, as well as establish an allowance for expected credit losses related to our accounts receivable as a whole. If circumstances related to specific customers change, or economic conditions deteriorate such that our past collection experience is no longer relevant, our estimate of the recoverability of accounts receivable could be further reduced from the levels provided for in the consolidated financial statements. As of December 31, 2024 and 2023, no single customer represented more than 10% of our consolidated accounts receivable balance.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost reflecting standard cost, which approximates the first-in, first-out method. Capitalized inventory costs include materials, labor, and manufacturing overhead that relate to the acquisition of raw materials and production into finished goods. The Company regularly reviews inventory for excess and obsolescence and records a provision to write down inventory to its net realizable value when carrying value is in excess of such value.

Property and Equipment

Property and equipment are recorded at cost and are depreciated over their estimated useful lives using the straight-line method. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the determination of net income or loss. Repairs and maintenance costs are expensed as incurred.

Intangible Assets (Excluding Goodwill)

Intangible assets include patents, trade names, customer relationships, acquired technology, and in process research and development ("IPR&D"). Intangible assets with a finite life are (1) amortized on a straight-line basis, with estimated useful lives typically ranging from 2 to 20 years, and (2) assessed for impairment whenever events or changes in circumstances indicate that their carrying value may not be recoverable, consistent with the Company's accounting policy for other long-lived assets with a finite life. Amortization expense is generally recognized within selling, general and administrative expense on the consolidated statements of operations.

Acquired IPR&D represents the fair value assigned to those research and development ("R&D") projects that were acquired in a business combination for which the related products have not received regulatory approval or commercial viability and have no alternative future use. If the project is not completed or is terminated or abandoned, the Company may have to recognize an impairment related to the IPR&D, which is charged to expense.

Goodwill

Goodwill is the excess of the cost of an acquired entity over the amounts assigned to the assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually, and is tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Impairment testing for goodwill is performed at the reporting unit level, with all goodwill assigned to a reporting unit.

During the fourth quarter of 2023, we elected to change the annual goodwill impairment testing date for each of our reporting units from November 30th to November 1st. The Company does not believe that this change to the annual impairment testing date represents a material change in the method of applying an accounting principle. This voluntary change is preferable because it provides management with sufficient time to complete goodwill impairment tests in advance of the Company’s year-end financial reporting and provides additional time for the execution of key controls and management review over the significant estimates and judgements inherent in the performance of the test. This change to the goodwill impairment testing date was not applied retrospectively as it was impracticable to do so without applying hindsight when developing key assumptions and estimates required to perform the test.

The testing of goodwill for impairment requires the Company to make several estimates related to projected future cash flows to determine the fair value of the reporting units to which goodwill has been assigned. The Company determines whether each reporting unit's fair value exceeds its carrying amount, including goodwill, based upon projections of future revenues, expenses, and cash flows discounted to their present value, as well as the application of a market approach. Internal operational budgets and long-range strategic plans are used as a basis for the cash flow analysis. The Company also utilizes assumptions related to working capital, capital expenditures, and terminal growth rates. The discount rate applied to the cash flow analysis is based on the weighted average cost of capital (“WACC”) for each reporting unit. These valuation approaches require the application of Level 3 valuation inputs (as defined in Note 23). An impairment is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit.

Long Lived Assets Impairment

We review long-lived assets ("asset groups") that are held and used for impairment whenever events or changes in circumstances indicate that the carrying value of an asset group may not be recoverable. The carrying value of an asset group that is held and used is not recoverable if it exceeds the sum of the undiscounted cash flows that are expected to result from the asset group's use and eventual disposition. If we determine that an asset group's carrying value is not recoverable, we must then compare the asset group's carrying value to its estimated fair value and record any excess carrying value over fair value as an impairment loss. Any impairment loss that is recognized is required to be allocated to the long-lived assets of an asset group on a pro rata basis, using the relative carrying amounts of the long-lived assets comprising the asset group, except that the loss allocated to an individual long-lived asset shall not reduce its carrying amount below its fair value whenever that fair value is determinable without undue cost and effort.

During the three months ended September 30, 2024, the Company concluded that there were indicators that the primary asset group underlying the Company's core operations should be tested for recoverability based upon the reporting of losses and negative cash flows for both current and historical reporting periods, combined with the significant decline in the Company's stock price during the period. Upon assessing this asset group for recoverability, the Company concluded that the asset group's carrying value exceeded the undiscounted cash flows that the asset group was expected to generate over the estimated remaining useful life of the asset group's primary asset, which was deemed to be acquired technology. Accordingly, the Company further tested this asset group for impairment as of September 30, 2024, using projected discounted cash flows, as well as a market approach based upon revenue multiples, to estimate the asset group's fair value.

Contingencies

We follow the provisions of ASC 450, “Contingencies,” which requires that an estimated loss from a loss contingency be accrued by a charge to income if (1) it is probable that an asset has been impaired or that a liability has been incurred and (2) the amount of the loss can be reasonably estimated. Legal costs related to the defense or settlement of a loss contingency are expensed when such costs are incurred and, accordingly, future legal costs expected to be incurred are not accrued as part of the liability recorded when a loss contingency has been deemed probable and estimable.

Foreign Currency Translation and Transactions

The local currency in which a subsidiary operates is generally considered its functional currency for those subsidiaries domiciled outside the United States ("foreign subsidiaries"). The functional currency financial statements of foreign subsidiaries are translated to U.S. dollars ("USD") in connection with the preparation of the Company's consolidated financial statements. Assets and liabilities of foreign subsidiaries are translated to USD at month-end exchange rates applicable to the reporting period. Income and expense items are translated to USD monthly using monthly average exchange rates. The effects of translating a foreign subsidiary's financial statements are recorded as currency translation adjustments and reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity.

Foreign currency transactions are those transactions whose terms are denominated in a currency other than an entity's functional currency. Foreign currency transactions that remain unsettled as of the end of a reporting period must be remeasured into the entity's functional currency, resulting in the recognition of a gain or loss when a change in exchange rate has occurred subsequent to the date on which the transaction was originally recognized or was most recently remeasured. The Company recognizes foreign currency transaction gains and losses within foreign exchange gain (loss), net on its consolidated statements of operations.

Research and Development Costs

R&D costs, consisting primarily of employee compensation, operating supplies, facility costs and depreciation, are expensed as incurred. When the Company is reimbursed by a collaboration partner for work the Company performs, it records the costs incurred as R&D expense and the related reimbursement as a reduction to R&D expense in its consolidated statements of operations.

Earnings Per Share and Net Loss Per Share

Basic earnings per share and basic net loss per share are calculated using the weighted-average number of common shares outstanding during each period. When applicable, diluted earnings per share is calculated based upon the inclusion of additional dilutive and potentially dilutive shares, which include shares issuable upon the exercise of outstanding stock options, upon the vesting of employee restricted stock-based awards, for settlement of accrued incentive compensation to be paid in shares (if and when related performance-based conditions have been satisfied as of the end of the reporting period), and to settle the portion of the convertible notes that may be settled in shares (where the conversion of such instruments would be dilutive).

Advertising Costs

Advertising costs are expensed as incurred and recorded in selling, general and administrative expense.

Pension Costs

We sponsor a retirement benefit for one of our non-U.S. subsidiaries in the form of a defined benefit pension plan. Accounting standards require the cost of providing this pension benefit to be measured on an actuarial basis. The application of these accounting standards require us to make assumptions and judgements that can significantly affect the measurement of our pension expense and our pension liability. Actuarial gains and losses resulting from both normal year-to-year changes in valuation assumptions and differences between assumptions and actual experience are deferred and amortized. Our critical assumptions in performing these actuarial valuations include the selections of the rate of compensation increase and the discount rate used to determine the present value of the pension obligations, each of which affects the amount of pension expense and pension liability recorded in any given period. Changes in the rate of compensation increase or discount rate could have a material effect on our reported pension obligations and related pension expense.

Equity Compensation Plans

We recognize compensation expense for our stock-based compensation programs, which provide for the issuance of stock options, restricted stock, restricted stock units (“RSU”), performance-based awards and market-based awards. The fair value of service-based awards is estimated at the grant date and recognized as expense ratably over the requisite service period of the award.

The fair value of performance-based awards is estimated on the grant date and expensed over an implicit or explicit service period when the performance condition is deemed probable of achievement. Performance-based awards that cliff vest are expensed ratably using the straight-line method; whereas, performance-based awards with graded vesting features are expensed using the graded vesting method. Stock compensation expense recorded for performance-based awards is reversed if the performance condition is no longer deemed probable of achievement or ultimately is not met. Some RSUs are granted with a performance measure derived from non-GAAP-based management targets or non-financial targets. Depending on our performance with respect to these metrics, the number of RSUs earned may be less than, equal to or greater than the original number of RSUs awarded, subject to a payout range.

The fair value of awards with market conditions ("market-based awards") is determined using a Monte Carlo valuation model and is expensed over an implicit or explicit service period regardless of whether the market condition is probable of achievement or not. Market-based awards that cliff vest are expensed ratably using the straight-line method; whereas, market-based awards with graded vesting features are expensed using the graded vesting method. Stock compensation expense is not reversed if the market condition is not met.

For all share-based payment awards, we recognize forfeitures when they occur.

Income Taxes

We and the majority of our domestic subsidiaries file a consolidated U.S. federal income tax return, while four of our domestic entities file separate U.S. federal income tax returns. Our non-U.S. subsidiaries file income tax returns in their respective jurisdictions.

Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for tax benefit carryforwards. Our deferred income tax assets and liabilities at the end of each period are determined using enacted tax rates.

We establish a valuation allowance for those jurisdictions in which the expiration date of tax benefit carryforwards or projected taxable earnings leads us to conclude that it is “more likely than not” that a deferred tax asset will not be realized. This evaluation process includes the consideration of all available evidence regarding historical results and future projections, including the estimated timing of reversals of existing taxable temporary differences and potential tax planning strategies. Once a valuation allowance is established, it is maintained until a change in factual circumstances gives rise to sufficient income of the appropriate character and timing that will allow a partial or full utilization of the deferred tax asset.

In accordance with ASC 740, “Income Taxes,” the impact of an uncertain tax position on our income tax returns is recognized at the largest amount that is more likely than not to be required to be recognized upon audit by the relevant taxing authority.

We include interest and penalties accrued in the consolidated financial statements as a component of income tax expense.

Operating and Finance Leases

We determine if an arrangement contains a lease at inception. We record both operating leases and finance leases on our balance sheet and do not separate non-lease components from our real estate leases. We exclude leases with a term of one year or less at the commencement date from our consolidated balance sheets.

Some leases include the option to purchase the leased asset, terminate the lease or extend the lease for one or more years. These options are considered in the determination of the estimated lease term when it is reasonably certain that an option will be exercised. Our leases do not contain any material residual value guarantees or material restrictive covenants.

Most of our leases do not provide an implicit rate; therefore, we use our incremental borrowing rate based on information available at the lease commencement date to determine the present value of the future lease payments.

Certain of our leases include variable costs. Variable costs include non-lease components that are incurred based upon actual terms, rather than contractually fixed amounts. In addition, variable costs are incurred for lease payments that are indexed to a change in rate or index. Because the right-of-use ("ROU") assets recorded on the balance sheet are determined based upon factors considered at the lease commencement date, subsequent changes in the rate or index that were not contemplated in the ROU asset balances at lease commencement result in variable expenses being recorded when these expenses are incurred during the lease term.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments," related to induced conversions of convertible debt instruments. The amendments in this ASU clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The amendments in this ASU permit an entity to apply the new guidance on either a prospective or retrospective basis. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses." The amendments in this ASU require public entities to provide disaggregated disclosure of expenses included within relevant income statement expense captions, as well as additional disclosures about selling expenses. This update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments in this ASU should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of the ASU or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements.

In March 2024, the FASB issued ASU 2024-02, "Codification Improvements - Amendments to Remove References to the Concepts Statements" (“ASU 2024-02”). This guidance is intended to remove references to various FASB Concepts Statements. The Board has a standing project on its agenda to address suggestions received from stakeholders on the Accounting Standards Codification and other incremental improvements to U.S. GAAP. This effort facilitates Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The resulting amendments are referred to as Codification improvements. The amendments in ASU 2024-02 are not intended to result in significant accounting change for most entities. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements.

In March 2024, the FASB issued ASU 2024-01, "Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards" (“ASU 2024-01”). This guidance is intended to improve U.S. GAAP. by adding an illustrative example to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether profits interest and similar awards (“profits interest awards”) should be accounted for in accordance with Topic 718, Compensation - Stock Compensation. The amendments in ASU 2024-01 are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. The amendments in ASU 2024-01 should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The Company is currently in the process of evaluating the effects of this ASU on our consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures." The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024, while permitted to be adopted on a retrospective basis. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. Upon adoption, this ASU is expected to result in the inclusion of additional tax-related disclosures in the footnotes to our consolidated financial statements.

Recently Adopted Accounting Standards

In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures." This ASU expands upon existing reportable segment disclosure requirements by requiring the disclosure of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss, as well as conforming interim period disclosures with annual period disclosures. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. The ASU is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this standard in the fourth quarter of our fiscal year ending December 31, 2024. Refer to Note 21 for our updated presentation and disclosures. The Company retrospectively applied the updated presentation and disclosures to all prior periods presented. Adoption of this ASU did not have an impact on the Company's results of operations, cash flows or financial position.

No other new accounting pronouncements issued or effective during the periods reflected in our consolidated statements of operations have had or are expected to have a significant impact on our consolidated financial statements.

Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Cash equivalents are valued utilizing the market approach for measuring the fair value of financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The carrying amounts of our cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value as of December 31, 2024 and 2023 because of the relatively short duration of these instruments.
