PURPOSE:To prevent the curing deformation of an obtained resin model by performing decimation scanning when light is scanned in a contour cross section to cure a photo-setting resin and successively performing scanning by procedure scanning between scanning lines subjected to decimation scanning. CONSTITUTION:An elevator cutting off light and having a cured resin placed thereon is provided in a photo-setting resin soln. tank. When the shaping region in one contour cross section is cured, at first, a scanning cured layer 54a is formed by performing first scanning and, next, a scanning line not adjacent to the scanning cured layer 54b subjected to scanning jut before is selected to perform second scanning to form a scanning cured layer 54b. Further, when a scanning cured layer 54c is formed by performing third scanning, a scanning line not adjacent to the scanning cured layers 54a, 54b during curing is selected by first and second scannings. Scanning is successively repeated by this procedure and a scanning line uncured and not adjacent is selected to perform scanning and, as a result, all of scanning lines are scanned. |
