Rapid Prototype Machine Projects Image of Part

A new rapid-prototyping machine uses a digital projector to shine an image of a CAD “slice” of a part onto a liquid photopolymer. This differs from stereolithography, which traces a path over the photopolymer with a moving laser beam. The Vanquish FC (Flash Cure) DLP (Direct Light Process) from Germany’s Envisiontec GmbH is sold here by Envisiontec, Inc., Ferndale, Mich. The machine is priced at $159,000, and theoretically has the capability to run faster than the traditional RP technologies. The current limitation is that there is currently only one material available for it. Parts made with that material are said to be durable and to have good surface detail. Envisiontec is producing machines in the U.S. The company started out with an earlier RP machine, the Perfactory. That smaller machine also uses DLP technology but projects light from beneath the material rather than above. Tel: (248) 582-0038 • www.envisiontec.com
