Abstract: PROBLEM TO BE SOLVED: To automatically form a structure for supporting a matter and a structure for fixing the matter to a stand in a stereo-lithography method for forming a three-dimensional matter. SOLUTION: A first means for prescribing a matter support structure especially formed in relation to a three-dimensional matter to be formed and a second means for automatically forming the three-dimensional matter in response to especially formed data are provided. The especially formed data prescribes a web sufficiently thin to facilitate the detachment from the matter after formed or a web sufficiently long to reach the cross section of the matter or a support fixing the edge of a layer to a proper place until a crosshatch vector is drawn or a support preventing the deformation of a cantilever or a support attaching the part of a layer becoming a drifted layer.
