                  SEVENTH AMENDMENT TO REIMBURSEMENT AGREEMENT

     THIS SEVENTH AMENDMENT TO REIMBURSMENT AGREEMENT (this "Amendment") is
entered into as of March 4, 2004, by and between 3D SYSTEMS CORPORATION, a
Delaware corporation ("Company"), and WELLS FARGO BANK, N.A., formerly know as
Norwest Bank Colorado, N.A. ("Reimbursement Bank").

                                    RECITALS

     WHEREAS, Company and Reimbursement Bank have entered into that certain
Reimbursement Agreement dated as of August 1, 1996, as amended from time to time
("Reimbursement Agreement") to provide for the reimbursement of a letter of
credit issued to support the issuance of Mesa County, Colorado, Industrial
Development Revenue Bonds in the principal sum of $4,900,000.00.

     WHEREAS, Company had been in default of at least one of the two financial
covenants under the Reimbursement Agreement and Reimbursement Bank had agreed to
waive compliance with such covenants until April 30, 2004 on the condition that
Company provided the Reimbursement Bank with evidence of a proposal from another
bank to replace the Letter of Credit and if not replaced, Company agreed to
retire $1,200,000 of the Bonds.

     WHEREAS, Company is no longer in default of the financial covenants, and
therefore Reimbursement Bank at this time will no longer require Company to
replace the Letter of Credit or retire $1,200,000 of the Bonds.

     WHEREAS, Reimbursement Bank and Company have agreed to certain changes in
the terms and conditions set forth in the Reimbursement Agreement and have
agreed to amend the Reimbursement Agreement to reflect said changes.

     NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties here to agree that the Reimbursement
Agreement shall be amended effective March 4, 2004, as follows:

     1.   Section 5.3, is hereby amended by adding the following to the end of
          the section:

          "Except as otherwise stated in this Agreement, all financial
          information provided to the Bank and all calculations for compliance
          with the financial covenants will be made using generally accepted
          accounting practices consistently applied ("GAAP")."

     2.   Section 8.2, is hereby amended as follows:

          Include "plus preferred stock" immediately following the words `Total
          Stockholders Equity'

          Add the following to the end of the section: "Net losses will not
          reduce the minimum tangible Net Worth requirement."

     3.   Section 8.6, is hereby amended to delete " both measured cumulative
          year-to-date and annualized" from the definition of the Fixed Charge
          Coverage Ratio and the definition of "EBITDA" and replace it with
          "measured quarterly to be calculated on a rolling four quarter basis"

     4.   Section 10.2, is hereby amended by adding the following to the end of
          the section:

          "Company acknowledges that upon the occurrence of an Event of Default,
          the Reimbursement Bank will not consider waiving the Event of Default
          unless and until Company complies with all requirements imposed by
          Bank which shall include but not be limited to the immediate
          retirement of $1.2MM of the Bonds. Funds for such repayment shall come
          first from the funds of the Company then held by the Reimbursement
          Bank, if any, and the balance from additional funds to be provided to
          the Trustee by the Company promptly upon notice from the Reimbursement
          Bank to the Company. In addition, any Event of Default will result in
          an increase to the letter of credit fee from 1 percent of the Stated
          Amount of the Letter of Credit to 1 1/2 percent of the Stated Amount
          of the Letter of Credit prorated from the occurrence of the Event of
          Default until the next August 1st, when the fee is due and continuing
          for the life of the Letter of Credit."

     5.   The Reimbursement Bank's agreement to modify the Reimbursement
          Agreement is contingent upon Company's compliance with the following
          conditions:
