Claim One:
1. A three-dimensional model forming device comprising: re-constructing means for re-constructing tomographic image data of multiple cross sections based on a plurality of projection data items covering a three-dimensional area of an object; threshold value setting means for setting a threshold value to establish a solid level in a tomographic image; binary coding means for converting the tomographic image data of multiple cross sections into binary image data of multiple cross sections based on the set threshold value so as to extract image data for a specific region; constructing means for constructing a three-dimensional image data based on the binary image data of multiple cross sections; display means for displaying a three-dimensional images as an artist concept of a three-dimensional model; threshold value changing means for changing the set threshold value so that a desired region is extracted; and model forming means for forming a three-dimensional model of the desired resin by hardening liquid region based on the binary image data of multiple cross sections.
