3D Systems Delays Filing its Form 10-Q and
Reports Preliminary Operating Results for
First Quarter 2007

     ROCK HILL, S.C., May 10, 2007 — 3D Systems Corporation (NASDAQ: TDSC), a leading provider of 3-D Modeling, Rapid Prototyping and Manufacturing solutions, announced that it filed today with the Securities and Exchange Commission (“SEC”) a Form 12b-25 indicating that it was unable to file its Quarterly Report on Form 10-Q by today’s initial filing deadline. A Form 12b-25 filing provides the company an automatic five-day extension for it to file its Quarterly Report on Form 10-Q and still be considered timely under SEC rules.

     The company also delayed issuing its operating results for the first quarter of 2007, but is reporting today its preliminary expectations for its operating results for that quarter. The company will hold a conference call and simultaneous webcast to discuss this delay and its preliminary results tomorrow morning, May 11, 2007, at 8:30 a.m., Eastern Time.

     The company’s delay in completing its financial statements for the first quarter of 2007 is due primarily to the time that it took to complete its Form 10-K for the year ended December 31, 2006 that the company filed with the SEC on April 30, 2007. The company intends to file its Form 10-Q and to issue its first quarter 2007 operating results as soon as practicable.

     The company expects to report revenue for the first quarter of 2007 in the range of $36 million to $37 million. Reflecting more normal patterns in its

3D Systems News Release Page 2

business, the company does not expect backlog to be significant at March 31, 2007.

     The company expects to report that sales of its engineered materials and composites continued to increase at a double-digit rate for the first quarter of 2007, reflecting the continued strong demand for these products.

     The company expects to report gross profit in the range of $15.5 million to $16.5 million for the first quarter of 2007, reflecting an anticipated improvement compared to the first quarter of 2006.

     The company expects to report an operating loss in the range of $1 million to $2 million as the company expects that higher operating expenses, primarily reflecting costs of the restatement of financial statements as previously disclosed, should more than offset the favorable effect of its anticipated higher gross profit.

     The company expects to report a net loss available to common stockholders in the range of $1.5 million to $2.5 million for the first quarter of 2007.

     The company also expects to report that at the end of the first quarter of 2007 it had $7 million of unrestricted cash on hand, primarily reflecting borrowings under its bank credit facility. The company expects to repay or refinance those borrowings at or before the expiration of that facility on July 1, 2007.

     There can, of course, be no assurance that the final results that the company reports will be within the ranges set forth above.

     “We believe that our results for the first quarter of 2007 will continue to reflect the favorable trends arising out of the resolution of the significant

3D Systems News Release Page 3

business disruptions that we encountered during 2006,” said Abe Reichental, 3D Systems’ president and chief executive officer. “We are gratified with the sequential comeback that we believe we are experiencing, and we continue to focus on our goals and our efforts to transform our company and the way we do business to establish growth and sustained profitability.”

Yesterday's Announcement We filed for an extension of time to file our first quarter Form 10-Q We have delayed releasing our first-quarter 2007 operating results until we finish the 10-Q We wanted to share with you preliminary results for the first quarter of 2007 There can be no assurance that the final results that we report will be within the ranges set forth today

First Quarter 2007 Expectations We believe that: Revenue for the first quarter should be in the range of $36 to $37 million Revenue for materials is expected to continue its double-digit pace of growth Gross profit should be in the range of $15.5 million to $16.5 million for the first quarter

We believe that: Operating loss for the first quarter should be in the range of $1 million to $2 million Net loss available to the common stockholders should be in the range of $1.5 to $2.5 million for the first quarter of 2007 Unrestricted cash on hand should be approximately $7 million, primarily reflecting borrowings under our Bank credit facility. We expect to repay or refinance those bank borrowings when they become due. First Quarter 2007 Expectations

State of Business We believe that the significant business setbacks and disruptions that we experienced in the course of implementing our strategic initiatives in 2006 are now largely behind us We are gratified with the progress we are making In the first quarter of 2007, we continued to incur abnormally high expenses related to the restatement and year-end audit Strong demand for our materials suggests that the demand for our products remains strong Our growing installed base, coupled with the integration of our new systems with proprietary materials' cartridges and our continuum of expert solutions, should improve the profitability of our business as revenue from materials continues to outpace the growth in systems

State of Business (continued) The stability of our revenue base should improve as consumables' sales rise as a percentage of the product mix relative to systems We are committed to completing our remediation efforts and to having state-of-the-art controls, procedures and processes We continue undeterred to focus on our goals and our efforts to transform our company and the way we do business to establish a strong record of sustained growth and profitability

Out of respect for other conference call participants, please ask one question and then return to the queue to ask additional questions. Because of the preliminary nature of our first- quarter 2007 results, we are not in a position today to comment further on them. All questions must be directed through the teleconference portion of this call. Questions via the web will not be accepted. Question & Answer Session
