Abstract
An improved selective deposition modeling method which produces a cold weld joint in an object formed by dispensing a single phase change material. The cold weld joint can be controlled so that a lower portion of the object can serve as a support structure for forming the upper portion of the object. Upon separation of the lower and upper portions along the cold weld joint, a downward facing surface is revealed on the upper portion exhibiting superior detail and quality compared to other downward facing surfaces created by conventional selective deposition modeling techniques. The method can readily be adapted for use by selective deposition modeling machines utilizing ink jet print heads dispensing a single phase change material.
