Until recently, engineers had to design and build prototypes in offices, based on 2D drawings. This is a time-consuming and expensive process. With the advent of new layer manufacturing and CAD/CAM technologies, prototypes can now be quickly produced directly from 3D computer models. There are many different technologies for rapid prototyping.
