PURPOSE:To enable the shortening of molding time of a solid model by laminating multi-tomographic slice images in which a subject part is divided in a plurality of blocks to mold cubic model pieces individually. CONSTITUTION:A three-dimensional data of a subject organ inputted is converted into multi-tomographic slice data at a lamination pitch of a modeling device 3 with a pre-processing section of a model data generator. The slice data thus obtained are divided into a plurality of blocks with a blocking device 4 grouping a plurality of continuous slice data as one block. Four slice data picked up one at a time from the respective blocks are arranged with a configuration device 5 being separated as one frame to form one layer of model data. With the modeling device 3, the lowest layer and the subsequent layer of the blocks are used sequentially to mold solid models of the blocks in a simultaneous process being laminated on one layer upon another already hardened. When the solid models of the blocks are completed, the model pieces are put together to finish a solid model of the subject organ thereby enabling the generation of the solid model in a short time.
