                   3D SYSTEMS ANNOUNCES SHARE BUY-BACK PLAN


     VALENCIA, Calif., May 6, 1997 - 3D Systems Corporation (Nasdaq - NMS:
TDSC) today announced that its board of directors has authorized the company to
buy up to 1.5 million of its shares in the open market and through private
transactions.

     The company has approximately 11.8 million shares of common stock
outstanding.

     "At its current trading levels, we believe the stock is an excellent value
and that the repurchase program will serve well our shareholders and the
company," according to Arthur B. Sims, the company's chairman and chief
executive officer.  "Additionally, the repurchased shares will be available for
issuance when outstanding stock options are exercised."

     "The actual number of shares repurchased, and the timing of the purchases,
will be based on 3D's stock price, general conditions and other factors," he
added.

     3D Systems Corporation develops, manufactures and markets solid-imaging
systems.  In manufacturing, 3D's products fabricate solid objects using input
from CAD/CAM 





systems, substantially reducing the time and cost of bringing new products to
market.  Major applications include rapid prototyping and tooling for products
in a variety of manufacturing industries worldwide, including automotive,
aerospace, medical, computer, electronic and consumer products.

     Except for the historical information contained in this news release, the
matters discussed are forward-looking statements that involve uncertainties
such as the timely development and acceptance of new products, the impact of
competitive products and pricing, industry-wide economic conditions, the
management of growth and other risks detailed from time to time in the
company's SEC reports, including its 1996 Form 10-K.
