VALENCIA, Calif.--(BUSINESS WIRE)--Oct. 14, 2002

3D Systems Corp. (Nasdaq: TDSC) today announced it plans to release four new SL materials for its stereolithography (SLA(R)) systems this quarter. By releasing the Accura(TM) SI 10, SI 20, SI 30 and SI 40, 3D Systems will provide a broad range of materials to provide customers with high temperature, durable and general-purpose properties for use across the SLA product line.

"This new range of materials exceeds what is currently available in the market. We are focusing on an ongoing effort to improve materials capabilities and are moving ahead with our development efforts to produce materials that meet the requirements of the rapid prototyping and Advanced Digital Manufacturing(SM) (ADM) markets," said Grant Flaharty, President and COO.

"Customers requiring a general purpose material are expected to find the Accura SI 10 material particularly useful. Already in use at customer sites, the SI 10 material experience to-date has shown it to be a far superior general purpose material to anything on the market today," said Senior Director Product Management, Mervyn Rudgley. "What makes this material superior is the combination of long vat life and accuracy in part building due to high green strength, humidity resistance and the advancements 3D Systems has made in material process to provide speed without compromising part quality. In combination with FinePoint(TM) supports, the SI 10 material can provide faster clean up time, reducing the labor cost associated with part finishing. The SI 10 material creates parts with a glossy top finish, excellent for thin wall parts and ideal for master patterns."

Next in the series of materials planned for introduction is the Accura SI 20 material. The SI 20 material (for the solid-state systems) is a durable white material offering high green strength, good throughput and humidity resistance. The Accura SI 20 material is ideal for snap-fit and RTV applications. "Process advancements from 3D Systems are incorporated into the build styles resulting in speed without compromising part quality. The Accura SI 20 material has an excellent combination of high green strength and recoatability, requiring no pre-dip delay and minimizing z-wait time, which results in a material that is up to 20% faster than competing materials on the SLA 7000 system," stated Rudgley.

Accura SI 30 material (for the solid-state systems) is a fast-durable material ideal for customers needing a high photo speed, low viscosity material for functional prototypes.

The fourth material in the Accura materials family is the SI 40 material. "Traditional SL materials have either provided high temperature capabilities, or toughness, but never both, until now. Accura SI 40 material is the first SL material on the market that combines high temperature with toughness. It is ideal for automotive applications including under the hood applications, wind tunnel testing, and flow analysis," continued Rudgley. "The Accura SI 40 material will produce parts with optical clarity, high flexural modulus and moderate elongation to break, with a high heat deflection temperature allowing it to be drilled, self-tapped and bolted on for true functional testing." With properties that mimic Nylon 6.6, SI 40 material will be available for limited release in mid-November 2002 with general availability by the end of the year on all SLA platforms.

"We are very excited about the developments and strides we have made in creating the range of materials that we are releasing. As we increase the versatility in offerings, our development efforts and partnerships are expected to expand as well. In providing customers with a `Total Solution' we have integrated expertise from around the world to develop and produce materials that provide customers with the end-use properties they have been requesting," concluded Flaharty.

About 3D Systems

Founded in 1986, 3D Systems, the solid imaging company(SM), provides solid imaging products and solutions to reduce the time and cost of designing products and facilitate direct and indirect manufacturing. Its systems utilize patented technologies to create physical objects from digital input used for design communication, prototyping and functional end-use parts.

3D Systems currently offers the ThermoJet(R) solid object printer, SLA(R) (stereolithography), SLS(R) (selective laser sintering) systems, and Accura(TM) materials (includes; photopolymers, metals, nylons, engineering plastics, and thermoplastics).

Product pricing in the U.S. ranges from $49,995, for the ThermoJet printer, to $799,000 for the high-end SLA 7000 system. 3D Systems multiple platform product line enables companies to choose the most appropriate systems for applications ranging from the creation of design communication models to prototypes to production parts.
