Rapid Prototyping Guide
Rapid Prototyping uses a standard data interface, implemented as the STL file format, to translate from the CAD software to the 3D prototyping machine. The STL file approximates the shape of a part or assembly using triangular facets. Typically, Rapid Prototyping systems can produce 3D models within a few hours.
Rapid prototyping elevates initial ideas to low-risk concept explorations that look like real products in no time. It allows designers to go beyond virtual visualization, making it easier to understand the look and feel of the design and compare concepts side by side.
