Rock Hill, South Carolina, Jul. 3, 2007 - 3D Systems Corporation (NASDAQ: TDSC), a leading provider of 3-D Modeling, Rapid Prototyping and Manufacturing solutions announced today the immediate availability of Accura® 55 Plastic, a tough and versatile new stereolithography material that simulates the look and feel of molded ABS.

Accura® 55 Plastic has been praised by advanced users for its unique performance attributes, which include increased productivity as a result of its ultra low viscosity that deliver better uptime, increased capacity utilization and substantially reduced post-processing and finishing labor. This material also provides engineers and designers with strong, functional models featuring fine detail and smooth surface finish.

Accura® 55 Plastic is 3D Systems’ latest addition to its comprehensive family of versatile and dependable Accura® materials. Parts produced on Viper™ Pro SLA® systems from Accura® 55 Plastic exhibit the desired accuracy for the most demanding functional prototypes and master patterns, well within tolerance and completely faithful to the CAD data from which they are made, and have the durability required for functional assembly tests.

Accura® 55 Plastic produces white ABS-like parts without molding or machining and is ideal for Rapid Prototyping and Rapid Manufacturing of automotive interior components, short-run production parts, electronic components, functional testing, concept and marketing models, and master patterns for urethane casting.

“We are very pleased to announce another significant material launch consistent with our commitment to lead through technology and expand the utility of our solutions through highly functional materials,” said Abe Reichental, 3D Systems’ president and chief executive officer. “Accura® 55 Plastic is a high-performance material designed to improve our customers’ bottom line by increasing productivity and reducing costs. Engineers and designers who are constantly looking for engineered plastics’-like performance from their models and functional prototypes will be impressed by the quality and toughness of this revolutionary material.

“In fact, we are deeply gratified that some of our advanced users such as Harvest Technology are already benefiting from the successful development of this industry-changing material.”

Harvest Technologies uses Accura® 55 Plastic for its customers who need fast Rapid Prototyping solutions.

“Based on the strong growth in our business, we will be adding a Viper™ Pro SLA® System to our fleet this month,” said Jason Morgan, Harvest’s stereolithography production manager. “Demand for rigid and durable models built with Accura® 55 Plastic has led us to select this material as the primary one for use with this new system. These models are used by our customers for a variety of applications to simulate end-use, injection-molded ABS parts. This addition will enable us to build even larger Accura® 55 prototypes to meet our growing customer demand.”

Accura® 55 Plastic is already available through a number of service providers, including Harvest Technologies and Tangible Express in the United States and Ogle Models and Prototypes in the United Kingdom.
