3 D Systems Inc

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.

3-D Systems Inc., a Canadian company whose primary unit is a Valencia operation with the same name, reported a second-quarter profit of $129,163, compared with a loss of $969,262 a year earlier. 3-D makes a machine that uses chemicals, a laser and a computer to rapidly build models of parts, consumer packages and other items that are used as prototypes by manufacturers. The company only recently began full-scale shipments of its machines, which has improved its sales and earnings.

3-D Systems Inc., the Canadian parent of a Valencia company with the same name, said it expects to report a profit of between $100,000 and $200,000 when its final figures for the second quarter that ended June 30 are released at the end of this month. 3-D Systems, which manufactures machines that make three-dimensional plastic models or prototypes of objects by using computer-aided designs and lasers, lost $984,736 in the second quarter of 1989. Sales in the latest period nearly doubled, to $7.

Ciba-Geigy reversed earlier plans and said it will retain its 37% ownership of 3-D Systems, the Canadian parent company of 3D Systems Inc. in Valencia. Ciba-Geigy, a Swiss conglomerate, announced in December that it planned to sell its 3-D holdings and Spectra-Physics, a San Jose company that is the biggest U.S. laser producer. 3-D Systems makes a machine that uses lasers, chemicals and a computer to rapidly make models of parts, consumer packages and other products for manufacturers.

3-D Systems Inc., a producer of machines that rapidly make models of industrial parts and other products, has claimed that Quadrax Corp. infringed certain existing and pending patents held by 3-D Systems. 3-D, a Canadian-based company whose sole production unit is based in Valencia, said it made its allegations in a letter to Quadrax, a Portsmouth, R.I., maker of plastic products. 3-D said it would "vigorously pursue all avenues to enforce its patents," including filing suit against Quadrax.

3-D Systems Inc., citing the economic recession, reported a fourth-quarter loss of $2.82 million compared with a year-earlier loss of $2.68 million. 3-D Systems is a Canadian company whose primary unit is Valencia-based 3D Systems, which makes equipment that combines a computer, laser and chemicals to rapidly make prototype models of industrial parts and other products.

3D Systems Inc. said it has settled patent litigation between the Valencia-based company and a Quadrax Corp. subsidiary. 3D produces machines that use a laser and chemicals to rapidly make prototype models of industrial parts and other products. The company had claimed in 1990 that Quadrax Laser Technologies Inc., a unit of Portsmouth, R. I.-based Quadrax Corp., had infringed certain existing and pending patents held by 3D.
