Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of 3D Systems Corporation and all majority and wholly-owned subsidiaries and entities in which a controlling interest is maintained (“3D Systems” or the “Company” or “we” or “our” or “us”). All significant intercompany accounts and transactions have been eliminated in consolidation. 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 income (loss) attributable to the RNCI is presented as an adjustment to the Company's consolidated net income (loss) to arrive at net income (loss) attributable to 3D Systems Corporation in the consolidated statements of operations and consolidated statements of comprehensive income (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 a reduction to the net income, or increase to the net loss, attributable to 3D Systems’ shareholders for purposes of reporting earnings or loss per share. See Note 11 for a summary of the activity related to the reported RNCI balance during the period. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim reports. Accordingly, our unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 (“2022 Form 10-K”). The year-end balance sheet data reported on our unaudited condensed consolidated balance sheet has been derived from the balance sheet included in our 2022 Form 10-K. The Company believes that the disclosures included in this Form 10-Q are adequate to make the information presented not misleading. In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations, and cash flows for the periods presented. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimates and assumptions. Our annual reporting period is the calendar year. Our results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year. All dollar amounts and other amounts presented in the accompanying footnotes are presented in thousands, except for per share information.
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 during the fourth quarter of each year, 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 done at a reporting unit level, with all goodwill assigned to a reporting unit. The test for impairment of goodwill requires the Company to make several estimates related to projected future cash flows to determine the fair value of the goodwill reporting units. The Company calculates the excess of each reporting unit's fair value over its carrying amount, including goodwill, utilizing a discounted cash flow analysis and other valuation techniques, as deemed appropriate. Internal operational budgets and long-range strategic plans are used as a basis for the cash flow analysis. The Company also utilizes assumptions for 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. An impairment is recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. During the quarter ended September 30, 2023, the Company experienced a significant decline in its market capitalization as a result of a decrease in its stock price, and during the month ended September 30, 2023, the Company’s market capitalization fell slightly below its consolidated stockholders’ equity balance. We do not consider this to constitute a sustained decrease in the Company’s stock price as of September 30, 2023. Furthermore, the Company performed a qualitative goodwill impairment assessment as of September 30, 2023 and concluded that it is not more likely than not that the fair value of either of its reporting units is less than the reporting unit’s carrying value as of September 30, 2023. As a result, we concluded that no triggering event had occurred that would require the Company to perform a quantitative goodwill impairment test for either of its two reporting units as of September 30, 2023. However, the Company’s market capitalization has declined further since September 30, 2023, and if such a decline results in the estimated fair value of either of our reporting units being lower than the respective reporting unit’s carrying value, the Company would need to record a non-cash goodwill impairment charge, which could be material, in a future period – including as of our upcoming annual impairment testing date of November 1, 2023 (reflecting our annual goodwill impairment testing date commencing as of the current fiscal year).
Variable Interest Entities (VIEs)	Variable Interest Entities (VIEs) Upon making an investment in an entity, we assess whether the entity is a 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 upon inception 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 analyze any investments in VIEs to determine if we are the primary beneficiary. We perform this assessment at the time that we become involved with a VIE and reevaluate our conclusion upon the occurrence of a reconsideration event. In evaluating whether we are the primary beneficiary, we evaluate 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. Performance of such analysis requires the exercise of judgment, and 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.
Equity Securities without a Readily Determinable Value	Equity Securities without a Readily Determinable ValueWe recognize investments in equity securities without a readily determinable fair value at cost minus impairment. We assess these investments for potential impairment if an event occurs or circumstances change that would indicate the carrying amount may be impaired. If applicable, impairment charges taken with respect to these investments are reported within interest and other income (expense), net in the consolidated statements of operations in the period in which an investment becomes impaired (see Note 7).
Equity Method of Accounting	Equity Method of AccountingThe Company accounts for an investment in a joint venture using the equity method of accounting because it does not have a controlling interest and is not the primary beneficiary; however, the Company has the ability to exert significant influence. Under the equity method of accounting, the initial investment is recorded at cost, and the investment is subsequently adjusted for the Company’s proportionate share of the net earnings or losses and other comprehensive income or loss of the investee. Intra-entity profits or losses associated with the Company’s equity method investment are eliminated until realized by the investee in transactions with third parties. Income or loss from this investment 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 will evaluate its investment in the joint venture for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.
Revenue Recognition	Collaboration and Licensing Agreements We enter into collaboration and licensing agreements with third parties. The nature of the activities to be performed and the consideration exchanged under these agreements varies on a contract-by-contract basis. We evaluate these agreements to determine whether they meet the definition of a customer relationship for which revenue should be recorded. 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 for these agreements based on an evaluation of the distinct performance obligations, the identification and evaluation of material rights, the estimation of variable consideration and the determination of the pattern of transfer of control for each distinct performance obligation. During the three and nine-month periods ended September 30, 2023, the Company recognized $7,896 and $16,099, respectively, of revenue related to collaboration arrangements with customers. During the three and nine-month periods ended September 30, 2022, the Company recognized $3,301 and $9,075, respectively, of revenue related to collaboration arrangements with customers. Our revenue recognized under collaboration and licensing agreements for the three and nine months ended September 30, 2023 includes the effect of the Company increasing its estimate of the variable consideration included in the transaction price related to one of its licensing agreements. The increase in estimated recognizable variable consideration was due to (1) the execution of a modification to the related customer contract and (2) the Company's determination that incremental revenue attributable to milestone payments that are contingent upon the achievement of contractual developmental criteria would be earned under the modified contract. As a result, during the quarter ended September 30, 2023, the Company recognized incremental services revenue of $4,452, which reduced our reported basic and diluted loss per share by $0.03 and $0.03, respectively, for each of the three and nine months ended September 30, 2023. Contract Balances During the nine months ended September 30, 2023, we recognized revenue of $23,498 related to our contract liabilities at December 31, 2022. During the nine months ended September 30, 2022, we recognized revenue of $28,850 related to our contract liabilities at December 31, 2021. Contract assets were $7,379 and $677 as of September 30, 2023 and December 31, 2022, respectively. The increase in the contract assets balance as of September 30, 2023 primarily relates to the increase in the estimated variable consideration included in the transaction price related to one of the Company's collaboration and licensing agreements (refer to the discussion above of Collaboration and Licensing Agreements), which has resulted in the recognition of incremental revenue for which the Company did not have the right to invoice as of the balance sheet date. Revenue Concentrations For the three and nine months ended September 30, 2023, one customer accounted for approximately 10.7% and 14.4% of our consolidated revenue, respectively. For the three and nine months ended September 30, 2022, one customer accounted for approximately 20.8% and 24.1% of our consolidated revenue, respectively. We expect to maintain our relationship with this customer.
Fair Value Measurements	Cash equivalents are valued utilizing the market approach to measure fair value for 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, restricted cash, accounts receivable, accounts payable, and accrued liabilities approximate fair value as of September 30, 2023 and December 31, 2022 because of the relatively short duration of these instruments.
