EXHIBIT 99.1 PRESS RELEASE EOS COMPLAINT AGAINST 3D SYSTEMS IN GERMANY DISMISSED AS WITHOUT MERIT: EOS TO PAY LITIGATION COSTS VALENCIA, Calif.--(BUSINESS WIRE)--Oct. 20, 2003--3D Systems Corp. (Nasdaq: TDSC - - News) today announced that on September 29, the Regional Court of Frankfurt-Main, Germany rejected in its entirety the complaint filed in May 2002 by EOS GmbH Electro Optical Systems against 3D Systems. EOS's complaint sought damages arising from 3D Systems' acquisition of DTM Corporation in August 2001, and alleged that the DTM purchase was not permitted under non-competition provisions in a 1997 contract between EOS and 3D Systems. Rejecting EOS's complaint, the Court's order states that the complaint was "not justified," that EOS has "no claim" against 3D Systems for breach of contract and that EOS's interpretation of the contract "makes no sense." EOS was ordered to pay the costs of litigation. "We are very pleased that the Court in Frankfurt decided to dismiss the complaint filed by EOS. We have maintained all along that EOS's suit was without merit," said Abe Reichental, 3D Systems CEO and president.
