The first rapid prototyping machine that can converts virtual concepts into physical objects was introduced in 1987. With the passage of time up-gradation and new techniques enables to complete these processes more quickly and accurately. Today’s rapid prototyping technology is completely different then used years ago, as the concepts are same to the earlier machines, that’s why today it is also called rapid prototyping. The best description of rapid prototyping is the manufacturing of objects through thin horizontal layers or through free-from-fabrication processes. This technology enables us to make big and complex designs in several hours (depending upon machine quality) to presents concepts physically. Rapid prototyping is used in almost every field of life like medical, automotive aerospace and construction etc.

There are many different processes involved in designing rapid prototypes, the major processes are

· Stereo lithography

· Selective Laser Sintering

· Fused Deposition Modeling

· Solid Ground Curing

· Laminated Object Manufacturing

Along with these processes many other processes are also introduced in the market such as Ballistic Particles manufacturing and 3D printing.

All above mentioned processes bases on latest techniques and technology start with nothing and ends up with a complete physical object and it is completely different process then older machines that make design with cutting and trimming a complete solid bloc of substances.

world’s fastest rapid prototyping processes fetch instructions from computer where we make a 3d Design by using different software’s. Therefore, CAD (computer aided designs) is essential to complete the processes of rapid prototyping.
