Abstract: A method for removing supports from a three-dimensional objected formed by selective deposition modeling. The three-dimensional object is formed from a curable phase change material and the supports are formed from a non-curable phase change material. The curable phase change material contains between about 5% to about 25% of a non-reactive wax in order to achieve the desired phase change characteristics of the material.

With the preferred build material having a freezing point of about 49.5° C., this is achieved by lowering the temperature between about 62° C. to about 52° C.
