Zusammenfassung:	An improved stereolithographic process for forming three-dimensional objects using an improved support structure and the improved support structure is described. The support structure is formed by using differential curing of the liquid media material to form solid supports with weak points at selected locations to facilitate support removal from a three-dimensional object and minimize post-processing.
