Abstract
A method and system for making a three dimensional product wherein the size and shape of a plurality of cross-sectional segments of the three dimensional object are determined which when assembled together in a particular sequence form the desired three dimensional shape. Thin layers of material in the shape of each of the cross-sectional segments are applied in the particular sequence in which they form the three dimensional object. The application of each of the layers is much like a lithographic printing process in that a resin may be applied by a roller in the shape of the cross-sectional segments.
