As a new innovation,rapid prototyping (RP) is a type of technologies that are used to produce physical objects layer-by-layer directly from computer aided design (CAD) data. This medthod are been used by dsigners to rpoduce tangible prototypes of their design very quickly, rather thasn just two dimentional pictures. The process may be applied to the production of metal, ceramic, and metal-ceramic composite parts. Rapid prototyping is often referred to as solid free-form fabrication or layered manufacturing. The advantages of this process is clear, development of physical models can be accomplished in significantly less time as compared to the machining process. The big user of 3D printing and rapid prototype system are the Aircraft manufacturer, Aerospace companies, Car manufacturer, Product designers, Shoe manufacturer, Metal, Plastic, medical, and dental industries.
