Rapid prototyping is a cost effective, quickly fabricated native model of an actual 3D dimensional part produced using CAD (Computer Aided Design) data. Popularly, it is getting done by two ways 3D printing & CNC Machining mostly. Apart from this FRP (Fiber Reinforcement Plastic) and Metal Casting are also the ways of producing prototype for small scale batch production.

Based on the application, product finishing, durability & budget etc. factors determine the choice of technology of rapid prototyping. Among the various technologies, 3D printing is very common and cost effective, also it takes very less time to develop prototype than any other technology.
