BACKGROUND OF THE INVENTION
By definition “rapid prototyping” is a group of techniques that can be used to quickly fabricate a scale model of a physical part or assembly using 3-dimensional computer aided design (CAD) data. In rapid prototyping, construction of the part or assembly is usually done in an additive, layer-by-layer fashion. Those...
