3-D Systems, a Valencia company that manufactures machines for rapidly making plastic models, said it won a new patent enlarging the scope of the technology to which the company has rights. With the new patent, 3-D said it believes that all "potentially competitive" devices by other companies would infringe on its patents. In April, 3-D accused Quadrax Corp. of Rhode Island of infringing on its patents and warned that it might file suit against the company. Quadrax had declined comment.

3D Systems Inc., a Valencia maker of machines that use a laser and chemicals to rapidly make prototype models for manufacturers, said it sued Quadrax Corp. and its Quadrax Laser Technologies unit for alleged patent infringement. Quadrax is a Portsmouth, R.I., company that has a laser modeling system called the Mark 1000. 3D Systems' suit was a cross-complaint to a suit filed last month by Quadrax in federal court in Providence, R.I.
