Conflict Minerals Report of 3D Systems Corporation

in Accordance with Rule 13p-1 of the Securities Exchange Act of 1934

This Conflict Minerals Report of 3D Systems Corporation (“3D Systems”) for the calendar year ended December 31, 2013 is being filed in accordance with Rule 13p-1 (“Rule 13p-1”) of the Securities Exchange Act of 1934. Please refer to Rule 13p-1, Form SD and Release No. 34-67716 for definitions of the terms used in this Conflict Minerals Report, unless otherwise defined herein.

In accordance with Rule 13p-1, upon conclusion of its good faith reasonable country of origin inquiry (“RCOI”), 3D Systems undertook due diligence intended to determine the conflict minerals status of raw materials used in its 3D printing centric design to manufacturing solutions, including 3D printers, print materials, on-demand custom parts services, 3D scan-to-CAD, freeform modeling and inspection tools. There is significant overlap between our RCOI efforts and the due diligence measures we performed. As a company in the 3D Printing industry, 3D Systems is several levels removed from the actual mining of conflict minerals. 3D Systems does not directly make purchases of raw ore or unrefined conflict minerals and makes no purchases in the Covered Countries. As described in our accompanying Form SD, we sought information from our direct suppliers, with those suppliers in turn seeking similar information within their supply chains to identify the original sources of necessary conflict minerals.

3D Systems due diligence measures were based upon the Organization of Economic Co-Operation and Development’s (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Second Edition.

3D Systems due diligence measures included:

Conducting a supply-chain survey with direct suppliers of material asking that they provide information on country of origin;

Performing a review of our products and finding that a limited number of products may contain tin, tantalum, tungsten, or gold; and

Recording the survey responses received in a database.

Our products that may contain one or more conflict minerals include 3D printers, print materials, on-demand custom parts services, 3D scan-to-CAD, freeform modeling and inspection tools. After exercising due diligence, the country of origin of conflict minerals contained within these products cannot be readily determined at this time. The facilities used to process the conflict minerals in these products are unknown. We are unable to determine this information with greater specificity at this time because our direct suppliers were unable to provide the information to us.

Due to the breadth and complexity of 3D Systems’ products and supply chain, many of our suppliers have not responded with verifications of the origin of materials supplied to 3D Systems. 3D Systems will continue to seek responses from its suppliers.
