                 3D SYSTEMS ANNOUNCES IMPROVED THIRD QUARTER RESULTS

         VALENCIA,  Calif., Oct. 15, 1998 -- 3D Systems Corporation (Nasdaq NMS:
TDSC) today  reported  third quarter net income of $477,000,  equal to 4 cents a
share, up significantly from a net loss of $2.1 million, or 19 cents a share, in
the year-ago period.
         Last  year's  third  quarter  included  approximately  $2.6  million in
non-recurring  expenses for restructuring  and write-off of in-process  research
and  development  associated  with the company's  acquisition of assets from EOS
GmbH of Germany.  Without those  charges,  the company would have reported a net
loss in last year's third quarter of approximately $500,000, or 4 cents a share.
         Revenues  for the three  months  ended  Sept.  25, 1998  totaled  $23.3
million, up from $22.3 million in the third quarter last year.
        For the current nine month period, the company posted net income of $1.4
million,  equal to 12 cents a share, on record  revenues of $70.9 million.  This
compares with a net loss of approximately $2.0 million,  or 18 cents a share, on
revenues of $65.6 million in the year-earlier period.

         "Our quarterly  revenue growth rate was dampened somewhat by the timing
of  product  shipments,"  said  Arthur B.  Sims,  chairman  and chief  executive
officer.  "A number of customers  placing orders in the third quarter  requested
delivery in the fourth.  Consequently,  backlog climbed substantially,  reaching
its highest level in six quarters."
         Sims  reported that the company  continues to experience  strength from
the  automotive  sector,  with one Big Three  manufacturer  placing an order for
three SLA-5000s during the third quarter. Two additional sales of SLA-5000 units
to Hitachi and Toyota in Japan were directly  influenced by the  performance  in
field trials of a new high temperature resin, he stated.
         "This new high temperature resin, currently undergoing market trials in
the United States and Japan,  substantially  exceeds the thermal capabilities of
any material we currently offer," Sims disclosed. "We expect this material to be
commercially available by year-end.
         "We enter the  fourth  quarter  with a  strengthened  backlog,  a solid
balance sheet and a sense of cautious optimism." he concluded.
         3D Systems  manufactures rapid product  development systems that enable
users to move from concept models to finished  parts faster,  at lower cost, and
at higher quality than traditional  methods.  3D Systems'  equipment  fabricates
solid  objects  using  digital   input  from   CAD/CAM/CAE   computer   systems,
substantially  reducing  the time and costs of bringing  new products to market.
Major applications include concept modeling, rapid prototyping and rapid tooling
for  products  in a wide range of  industries  worldwide  including  automotive,
aerospace, medical, electronic and consumer products.
       Except for the historical information contained in this news release, the
matters  discussed  include  forward-looking  statements  that involve risks and
uncertainties  including the  availability  and acceptance of new products,  the
impact of  competitive  products  and  pricing,  the  ability of the  company to
continue  to  contain  expenses,  dependence  on  key  personnel,  industry-wide
domestic and international economic conditions,  and other risks detailed in the
company's SEC report on Form 10-K for the year ended December 31, 1997.
