PURPOSE:To shape in a short time, highly-accurately and inexpensively a three- dimensional form without making an optical mask into a large size, by a method wherein the mask is scanned on cured resin in a monoaxial direction along with a light source and an optical transmission part of an optical mask is changed continuously by corresponding to horizontal sectional forms each. CONSTITUTION:An optical mask 3 such as a liquid crystal shutter plate whose optical transmission part is changed electrically by corresponding to a horizontal sectional form of a three-dimentional object 7 which is desirous to obtain is installed on this side of photosetting resin 2. Then moving scanning of the optical mask 3 is performed on the surface of liquid setting resin 2 integrally with a light source in a monoaxial or biaxial direction by an XY stage driver 11. The optical transmission part of the optical mask 3 is changed electrically in accordance with the scanning by corresponding to the horizontal sectional form by a driver 6 and a layer is thinned in order by size of an extent of the optical mask. |
