Rapid Prototyping

Introduction:

Rapid prototyping is usually referred to as additive fabrication, because the process involves building up the object by the addition of successive layers. CAD drawing information is downloaded to the rapid prototyping machine, which uses that data to incrementally create the object.

Rapid Prototyping involves transforming virtual designs from CAD or 3D modeling software into virtual cross-sections. The rapid prototyping or 3D printing machine reads data from a CAD drawing and lays down successive layers of plastic, constructing the 3D-prototype from a series of cross-sections. These layers, which correspond to the virtual cross-section from the CAD model, are glued together or fused ( using a laser or UV light) automatically to create the final shape.
