Abstract
A photo-setting resin is shaped into a three-dimensional resin model by scanning successive resin solution layers of a photo-setting resin solution with a radiation beam to form a stack of scanned set layers of photo-setting resin, each of the successive resin solution layers having a shaped region of an isometric section. The radiation beam is scanned along a contour line of the shaped region to set the shaped region along the contour line, and scanned in a raster scanning mode to set the shaped region inwardly of the contour line. Specifically, the radiation beam is scanned along a first line which is spaced a first distance inwardly from the contour line thereby to set the shaped region along the first line, and the radiation beam is scanned inwardly of a second line which is spaced a second distance inwardly from the contour line thereby to set the shaped region inwardly of the second line. The first distance is smaller than the second distance.
