Production of 3-D prototypes from computer generated models

摘要

A method and apparatus for forming a prototype or product article generated in the form of a three dimensional computer model includes splitting the model into a number of, preferably planar segments, and then sending the data for each segment to a means for applying or creating a build material such as a resin or thermoplastic material onto separate sheets of material to create article segment forms. This process is repeated to provide a series of sheets each incorporating a segment of the article, the sheets are stacked, in order, and the build material cured, before the sheet material with no build material applied thereto is removed to leave the article formed from the build material.
