Presently, a dominant technology for producing physical models for testing and evaluation purposes has been rapid prototyping (RP). CNC prototyping has its own limitations involving the geometric errors due to machine tool accuracy and inaccuracy of machining and thermal errors arise due to frictional forces between the tool and the job (Kosinar and Kuric 2011). Other disadvantages includes the loss of the raw material as the process is subtractive, the fixtures required in CNC machining have their different complicated designs for different types of parts, increased costing due to manufacturing of valves and fixtures themselves, tedious programming associated with the CNC’s and hiring skilled labor for overviewing the process that adds to its cost (Lennings, 2000). Also the CNC machines are unable to manufacture parts with non-linear geometry or parts having complicated interiors. That’s where RP comes, introduced in the late 1980’s, are now established method of reducing work done on product development and its cost and lead times. Considering mass production CNC prototype may be cheaper but for manufacturing a single intricate product, RP prototype would have an upper hand.
