To eliminate the conventional time-consuming and difficult work due to the indispensability of manual work for manufacturing a molding obtained through the overemphasization of distinctive features of a three- dimensional matter as a mascot.

This device consists of a three-dimensional shape inputting means 1 for outputting three-dimensional shape data through the scanning of the outward show of the three-dimensional matter, a feature emphasizing means 2 for converting the three-dimensional shape data so as to extract and emphasize the featured portions from the three-dimensional shape data outputted from the three-dimensional shape inputting means 1 in order to output an emphasized three-dimensional shape data and a stereo lithographing means 4 for producing the modeling on basis of the emphasized three-dimensional shape data outputted from the feature emphasizing means 2.
