*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	On April 5, 2011, The Clark Estates, Inc. sold 102,000 shares as reported in its Amendment 10 to Schedule 13D filed on April 6, 2011. This disposition reduced the shares of 3D Systems Corporation (the "Corporation") common stock owned by the various investment accounts for which The Clark Estates, Inc. provides administrative services to 1,458,857 shares as of that date. See note 4 below. As a result of the Corporation's two-for-one stock split distributed to the Corporation's stockholders on May 18, 2011, the shares of the Corporation's common stock owned by such investment accounts as of that date was 2,917,714. This amount was incorrectly shown as 3,121,714, which did not account for the sale on April 5, 2011, in each of Mr. Moore's Form 4 filings on May 6, 2011, May 19, 2011, November 8, 2011 and November 16, 2011.
(2)	This Form 4/A is being filed in connection with the most recent November 16, 2011 Form 4 filing to correctly reflect the number of shares of the Corporation's common stock owned by such investment accounts as of November 16, 2011.
(3)	These securities are owned by various investment accounts for which The Clark Estates, Inc., a New York corporation, provides administrative and management services. The Clark Estates, Inc. may be deemed to be the beneficial owner of those securities. The Reporting Person is President and a director of The Clark Estates, Inc.
(4)	The Reporting Person disclaims beneficial ownership of these securities as well as any pecuniary interest therein.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
