                3D SYSTEMS ANNOUNCES THIRD QUARTER RESULTS
                                     
          VALENCIA, Calif., October 22, 1997--3D Systems Corporation
(Nasdaq-NMS :TDSC) announced today that third quarter revenues increased 13
per cent to a record $22.3 million from $19.8 million a year ago.
          During the quarter, the company incurred one-time charges amounting
to $3.1 million. The write-offs included in-process R & D related to the
acquisition of assets from EOS GmbH of Germany, 3D's principal European
competitor, restructuring expenses, and inventory adjustments stemming
primarily from the transition to a new generation of products announced in
the quarter.
          After giving effect to these items, the company posted a net loss
for the quarter of $2.1 million, or 19 cents a share, compared with net
income of $1.0 million, or nine cents a share, in the prior year. The
comparable 1996 quarter included a charge of $430,000 from 3D's acquisition of
Keltool, Inc. 
          For the nine months, revenues rose 14 per cent to a record $65.6
million from $57.5 million in 1996. Including the third quarter nonrecurring
charges, the net loss for the period amounted to $2 million, or 18 cents a
share, compared with net income of $2.9 million, or 25 cents a share, a year
ago.



          According to Arthur B. Sims, chairman and chief executive officer,
"14 of the new high-performance SLA-5000 rapid prototyping systems were shipped
in the final weeks of the quarter and we are pleased with the market reaction
to the announcement of this new product generation."
          Commenting on the company's business internationally, he said: "In
Europe, the EOS acquisition has already enabled us to convert three former
EOS customers to 3D products and we are looking forward to adding additional
new accounts, including recurring sales of maintenance service and supplies
to the EOS customer base.
          "Our business in the Asia-Pacific market continues to expand
rapidly. Sales increased more than 200 per cent from the quarter a year ago,
putting us ahead 120 per cent year-to-date."
          Sims concluded: "In the United States, our largest market, the
orders flow increased sharply over last year's third quarter and, while U.S.
orders are not yet at a satisfactory level, we are pleased with the
improvement in the third quarter."
          3D Systems develops, manufactures and markets solid-imaging systems
that substantially reduce the time and costs of bringing new products to
market by quickly fabricating mechanical parts after they are designed by
engineers using CAD computer systems. Major applications include rapid
prototyping and tooling for products in a variety of manufacturing industries,
including automotive, aerospace, medical, computer, electronic and consumer
products.
