VALENCIA, Calif., July 12, 1999 - 3D Systems Corp. (Nasdaq NMS: TDSC) today announced that the company will begin a search for a chief executive officer to succeed Arthur B. Sims, who will continue to serve as chairman of the board. Mr. Sims will remain as chief executive until his successor has been chosen.

Mr. Sims, age 61, will serve on the board's selection committee, which has retained the executive recruiting firm of McCray, Shriver, Eckdahl & Associates of Los Angeles to conduct the search.

"During the 1990's, 3D Systems firmly established its position as the worldwide leader in solid imaging," Mr. Sims said. "In line with the company's management transition plan, we have initiated a search for a dynamic and highly qualified top executive to lead 3D Systems into the next decade, and oversee what we are confident will be an era of growth and opportunity for the company."

Mr. Sims joined 3D Systems in 1991 as chief executive officer, and has served as chairman since 1993.
