The term rapid prototyping (RP) refers to a class of technologies that can automatically construct physical models fro Computer-Aided Design (CAD) data. These "three dimensional printers" allow quick production of physical prototypes from 3D computer models. Rapid Prototyping is an additive manufacturing process, which builds object layer by layer.
Rapid prototyping machine installed at IIT Delhi is based on Selective Laser Sintering (SLS) technology. The process uses polymer powder (polyamide) as a raw material to build artifacts irrespective of their complexity. Presently prototypes are made in Polyamide (Nylon). However the machine can be used to produce parts in other materials such as glass-filled polyamide, Alumide (Aluminium mixed polyamide), primecast (wax type of material) and Somos (rubber-like material).
The input to machine is 3D CAD model of part to be produced in stl format. The facility has a provision to create stl files from CAD models prepared in Pro/engineer and AutoCAD.
