3-D Accuses Quadrax of Patent Infringement

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’s machines combine chemicals, a laser and a computer to rapidly produce plastic-like models of auto parts, consumer packaging and other items that manufacturers use as guides in developing new products.

Quadrax Chairman Richard A. Fisher declined comment on 3-D’s letter.
