        (3D-SYSTEMS)(TDSC) 3D Systems Announces Cross-License with Sony
                           (Business Wire; 05/26/98)

VALENCIA, Calif.--(BUSINESS WIRE)--May 26, 1998--3D Systems Corp.
(Nasdaq/NMS:TDSC) Tuesday announced that it has signed a patent
cross-license agreement with Sony Corp.

Under the agreement, 3D Systems granted Sony a royalty-bearing license
under 3D Systems' patents to produce and sell stereolithography machines in
the Asia-Pacific area, while Sony granted to 3D Systems a royalty-free
license under Sony's patents to produce and sell both stereolithography
machines and 3D Systems' multi-jet modeling machine known as the "Actua"
throughout the world.

According to A. Sidney Alpert, 3D Systems' vice president and general
counsel, the cross-license agreement with Sony establishes the importance
of 3D Systems' patents to manufacturers of stereolithography machines in
the Asia- Pacific area. "Of the three principal manufacturers of
stereolithography machines utilizing 3D Systems' patents in Asia-Pacific,"
he said, "Sony has been the first to recognize the value of our patents
with the execution of this cross-license agreement, by agreeing to a
payment for past use of these patents as well as an ongoing royalty, while
granting royalty-free rights on a worldwide basis to 3D Systems."

He noted that 3D Systems presently has a patent infringement action in
Japan against a principal infringer, Teijin Seiki Corp. Alpert added, "We
intend to vigorously pursue infringers of our patents, not only in the
Asia- Pacific area, but on a worldwide basis. Our view is to limit the
granting of licenses to the Asia-Pacific area, while maintaining our right
to be the only practitioner of stereolithography in the rest of the world."

3D Systems manufactures rapid product development .....
