Abstract
The dimensional boundaries of a part are determined in a computer CAD/CAM system, including x, y, and z dimensions. A reference surface is provided and a first incremental layer of mold material is formed on the reference surface. The first incremental layer of mold material is selectively interrupted to define at least one dimensional boundary of the object. A first incremental layer of object material is formed upon at least the reference surface and assumes the dimensions defined by the interruption in the layer of mold material. The steps of forming incremental layers of mold and object material are repeated until the object or part is fully fabricated and all dimensional boundaries are defined.
