>The Rapid Prototyping Report in 1992 defined RP as

The Fabrication of a physical, three dimensional part of arbitrary shape
directly from a numerical description (typically a CAD model) by a quick,
highly automated and totally flexible process.

Does this definition define what you do with rapid prototyping? Should it
be expanded and if so how would you change it?<


I've been using the following to briefly define/describe RP:

Rapid prototyping (RP) is a relatively new class of technology used for
building physical models and prototype parts from 3D computer-aided design
(CAD) data. Unlike CNC machines tools, which are subtractive in nature, RP
systems join together liquid, powder and sheet materials to form complex
parts. Layer by layer, RP machines fabricate plastic, wood, ceramic, and
metal objects based on thin horizontal cross sections taken from a computer
