Rapid prototyping services in India. Rapid prototyping is the fast physical fabrication of a part, model or assembly using 3D CAD design. This creation of the object is usually achieved using additive manufacturing, also known as 3D printing. Rapid prototyping uses various manufacturing technologies like layered additive manufacturing, high-speed machining, casting, moulding, and extruding. The different types of rapid prototyping are stereolithography or vat photopolymerization, selective laser sintering, fused deposition modeling or material jetting, selective laser melting or power bed fusion, laminated object manufacturing, digital light processing, and binder jetting. Rapid prototyping is used by product designers for manufacturing representative prototype parts in a rapid manner. Originally it was used to create parts and scale models in the automotive industry and is now used widely in medical and aerospace industries.
