Rapid prototyping techniques shorten the time required for product development. The ability to translate a 3D computer model into a physical model in a very short time enables you to evaluate your products to ensure a basic fit, form and function. 

Stereolithography is the most widely used type of rapid prototyping.  Stereolithography produces 3D parts by curing successive layers of UV-curable resin.  The parts of the resin that the laser cures in each layer is defined by a CAD model of the part.
