PURPOSE:To mold an accurate molding model on diagram data in a short time by lighting photosensitive resin liquid in various directions and curing sections not lighted only. CONSTITUTION:A machine is constituted of a computer having liquid crystal channels 2-4 forming a face (x), a face (y) and a face (z), fixed to the three faces not in parallel each other, out of a water tank 1 made of a transparent material such as glass or the like and its respective faces, light sources 5-7 fixed to the rear of respective liquid crystals and a computer 8 having three dimensional diagrams of a model to be molded and controlling the liquid crystal channels 2-4 and a monitor 9 for the computer 8. For the light sources 5-7, light of good directivity such as, for example, surface emission ultraviolet ray laser light or the like is used. Photosensitive resin liquid 10 is put in the water tank 1, and the diagrams developed on the faces (x), (y) and (z) are computed by the three-dimensional data of a molding model 11 and liquid crystal channels 2-4 of respective faces are controlled in a manner that light is transmitted through only the computed diagrams. Then, the amount of light in the light sources of respective faces is adjusted so that the photosensitive resin liquid 10 is cured only on the sites where light from the respective three faces (x), (y) and (z) is applied and emitted. The molding model 11 is formed by said arrangements. |
