VALENCIA, Calif., February 16, 1999 - 3D Systems Corp. (Nasdaq NMS: TDSC) announced today that it has granted another license for its proprietary tooling technology solution, 3D Keltool, to a subsidiary of St. Paul, Minn. based Rapid Design Technology (RDT). Terms of the transaction were not disclosed.

Along with the license, a newly created RDT subsidiary, Rapid Tooling Technology, will acquire 3D Systems' St. Paul, Minn. facility to offer tooling services and consultation. RDT's new venture extends an association with the company that dates back two years, when it became a reseller of 3D Systems' office concept modeler.

"We are delighted to deliver added value to RDT," said Charles Wilson, vice president of worldwide sales and marketing. "With the growth of our 3D Keltool program, we have followed our strategy to focus on research and development and offer more complete solutions to our customers. 3D Systems will act as a liaison between our Keltool partners and our installed systems base - to foster collaboration between the two, and expand the range of options available to our customers."

Wilson indicated that 3D Systems would continue to operate its 3D Keltool facility in Valencia, California. That location serves as the nerve center for 3D Keltool R&D and training, as well as producing benchmark inserts for prospective partners and for on-site customer visits.

"Interest in 3D Keltool is growing, and we intend to build our business worldwide," Wilson said. "The technology enhances the competitive position of moldmakers by bringing a fast, accurate, versatile, and cost-effective solution to tooling. And with respect to customers, 3D Keltool offers a revolutionary process to meet their ever-increasing time-to-market, competition, and productivity challenges."
