VALENCIA, Calif., February 5, 1999 - 3D Systems Corp. (Nasdaq NMS: TDSC) announced today that its founder, Vice Chairman and Chief Technology Officer Charles W. Hull, will retire from the company on Feb. 28. He will continue to serve as a consultant to the company and on its board of directors.

Mr. Hull founded 3D Systems with other partners 13 years ago and quickly brought to market an unprecedented product that could transform digital data into physical solid objects, based on imaging technology he invented.

Today, 3D Systems is a global company with more than 450 employees and is recognized as the worldwide market and technology leader in solid imaging. Its systems are used by a variety of industries--including automotive, aerospace, consumer products, consumer electronics, toys, entertainment, and medical--to rapidly produce prototype parts, tooling masters and other objects designed with computer software.

"In addition to breathing life into 3D, Chuck has guided the company from its early start-up days to today," said Arthur B. Sims, chairman and chief executive officer. "We are pleased that going forward we will continue to have the benefit of his insights, support and friendship."

Mr. Hull is a named inventor on 47 United States patents, plus numerous foreign patents, in the fields of ion optics and solid imaging. He is listed in the Who's Who Registry of Business Leaders.

In 1995 he received the prestigious Rank Prize, presented by The Rank Foundation at the Royal Society of Medicine in London, in recognition for his development and commercialization of stereolithography. In 1996 he received the William T. Ennor Manufacturing Technology Award by the American Society of Mechanical Engineers, and was also named Entrepreneur of the Year by Ernst & Young and Inc. magazine. In 1997 he received the Albert M. Sargent Progress Award by the Society of Manufacturing Engineers. Earlier he received the Jaquard Award, bestowed by the Numerical Controls Society.

Mr. Hull served as president of 3D Systems from 1986 to 1997.

Prior to founding 3D Systems, Mr. Hull served six years as vice president of engineering at UVP, Inc. in San Gabriel, Calif., a systems manufacturing company. It was at UVP that he first developed and patented the stereolithography solid imaging processes that led to the founding of 3D Systems. Before that, he spent 10 years as engineering manager at DuPont's Photo Products Division in Monrovia, Calif., concentrating on development and production of analytical equipment, including mass spectrometer systems. Prior to DuPont, he was a senior engineer at Bell & Howell.

Mr. Hull was born in Grand Junction, Colo. and received his bachelor of science degree in engineering physics from the University of Colorado. He resides in Southern California with his wife, Anntoinette. They have two children and two grandchildren.
