                 3D SYSTEMS ANNOUNCES NEW MATERIAL THAT ENHANCES
                   PRODUCTIVITY OF ITS SOLID IMAGING SYSTEMS

VALENCIA, Calif.--(BUSINESS WIRE)--Nov. 1, 1999--3D Systems Corp. (Nasdaq:TDSC -
NEWS) today announced the availability of Cibatool(R) SL 7510, a multipurpose
resin that greatly expands the productivity and range of applications for its
SLA(TM) 3500 and SLA 5000 systems.

SL 7510 was initially announced last February for use exclusively with the
company's high-end system, the SLA 7000.

Speed improvements, combined with a .002 inch layer resolution, make this resin
ideal for tooling buildstyles requiring smooth surfaces. Using the EXACT(TM)
buildstyle, SL 7510 builds parts up to one-and-a-half times faster than the
current multipurpose resin offerings for both the SLA 3500 and SLA 5000 systems,
and up to two times faster using the FAST(TM) buildstyle.

The resin is well-suited for foundry work using the QuickCast(TM) application,
where the 3D Systems Technology Center has found that build times for SL 7510
are approximately twice as fast as SL 5510.

"Our experience with SL 7510 has been excellent," stated Todd Mueller, senior
prototyping engineer at 3D Systems' Technology Center. "Good photo sensitivity
with minimal Zwait and Predip allows us to build parts very quickly, and provide
rapid turnaround to our customers. In addition, parts built with SL 7510 exhibit
smooth sidewalls, resulting in improved part quality."

The resin is also ideal for functional prototypes, as it offers excellent
durability and impact resistance properties combined with part clarity. As a
result, SL 7510 is well suited for functional and limited snap-fit testing, as
well as molding applications.

"Our favorite characteristic of SL 7510 on the SLA 3500 machine is the 10%
elongation at break," continued Mueller. "As a result, it provides the
flexibility for snap-fit applications, while remaining robust."

According to Diana Kalisz, senior director of SLA programs, "While this material
performs very well on the SLA 7000, it exhibits substantially greater elongation
at break properties when utilized with the SLA 3500 and SLA 5000, expanding the
applications for which these stereolithography parts can be used."

SL 7510 for the SLA 3500 and SLA 5000 machines is available for purchase
effective immediately.

SL 7510 is the latest development in an ongoing relationship between 3D Systems
and Ciba Specialty Chemicals to develop advanced photopolymers for
stereolithography. 3D Systems is the exclusive worldwide distributor of Ciba's
photopolymer products produced under this development partnership.
