     This Amendment No. 1 is filed in accordance with Rule 13d-2 of the
Securities Exchange Act of 1934, as amended, by G. Walter Loewenbaum II and
refers only to information which has materially changed since the filing of the
Schedule 13D by Mr. Loewenbaum on May 22, 1997. The items identified below, or
the particular paragraphs of such items which are identified below, are amended
to add the information as set forth below.


ITEM 2.  IDENTITY AND BACKGROUND.

     This statement is being filed by G. Walter Loewenbaum II. Mr. Loewenbaum is
Managing Director of LeCorgne Loewenbaum LLC, an investment banking firm whose
address is 1100 Poydras Street, Suite 1750, New Orleans, Louisiana 70163.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     The purchase reported in this statement was acquired with the personal
funds of Mr. Loewenbaum.

ITEM 4.  PURPOSE OF TRANSACTION.

     Mr. Loewenbaum acquired the shares for investment purposes. Mr. Loewenbaum
does not have any plans or proposals that relate to or that would result in any
of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D,
except that Mr. Loewenbaum may acquire additional shares of common stock, par
value $0.001 per share (the "COMMON Stock"), of 3D Systems Corporation (the
"ISSUER") in open market transactions or otherwise. Any decision of Mr.
Loewenbaum either to purchase additional shares of Common Stock or to dispose of
any shares will take into account various factors.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

     (a), (b) As of the date of the filing of this statement, Mr. Loewenbaum, in
the aggregate, beneficially owns 1,305,013 shares of the Common Stock, which is
approximately 8.5% of the shares of the Common Stock believed to be outstanding.
These shares are held by Mr. Loewenbaum with sole voting and dispositive power.

     (c) Effective as of May 5, 2003, Mr. Loewenbaum purchased from the Issuer
in a private placement transaction 208,334 shares of the Issuer's Series B
Convertible Preferred Stock, par value $0.001 per share (the "PREFERRED
SHARES"), at $6.00 per share, for an aggregate purchase price of $1,250,004
pursuant to a Securities Purchase Agreement (the "SECURITIES PURCHASE
AGREEMENT"). Each Preferred Share is convertible at any time after issuance into
the number of shares of Common Stock as is determined by dividing (i) the amount
of the liquidation preference of the Preferred Share on the date the certificate
representing the Preferred Share is surrendered for conversion by (ii) $6.00
(subject to adjustment as set forth in the Certificate of Designations). The
liquidation preference of each Preferred Share is equal to the sum of $6.00 and
an amount equal to all accrued or declared but unpaid dividends on the Preferred
Share. Each Preferred Share accrues cash dividends at the rate of 8% per share
per annum (subject to adjustment), which is cumulative to the extent it is not
declared and paid. Pursuant to the Securities Purchase Agreement, the Issuer
agreed to file a registration statement with the Securities and Exchange
Commission with respect to the shares of Common Stock issuable upon conversion
of the Preferred Shares.

     (d) Not applicable.

     (e) Not applicable.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
        SECURITIES OF THE ISSUER.

     Except for the Securities Purchase Agreement and except as set forth in Mr.
Loewenbaum's initial filing on Schedule 13D, Mr. Loewenbaum does not have any
contract, arrangement, understanding or relationship (legal or otherwise) with
any person with respect to any securities of the Issuer, including but not
limited to the transfer or voting of any of such securities, finder's fees,
joint ventures, loan or option agreements, puts or calls, guarantees of profits,
division of profits or losses, or the giving or withholding of proxies.
