Rapid Prototyping Process  ( Damvig ) “ A computer-controlled laser beam is scanned across the surface of a vat of liquid photopolymer, instantly solidifying the liquid at each point of contact. Using data generated from a CAD file, individual cross-sections of the three-dimensional geometry are solidified in turn to build up a solid part layer by layer. In this way even highly complex geometries can be built in a few hours without requiring any tools. “
