Rapid prototyping is automated construction of the physical object by using preservative layer manufacturing methods. At present world, it is available in different kinds of formats such as selective laser sintering, stereolithography, huge range of the 3d printing methods and fused deposition modeling. It is widely used in the numbers of applications such as engineering, medical and industrial discipline. Rapid prototyping could be defined as the modeling technique that may speed up and improve development of the new products. It is the amazing process which is used computer aided techniques and tool like 3d printing in order to make physical product models for the production analysis and tooling.
