Abstract

PURPOSE:To form a three dimensional product by a method in which a liquid tank is filled with photosensitive setting resin liquid, and the controlling data of the coordinates and the light intensity of a point light source is directly changed, while carrying the point light source to the objective point in the liquid. CONSTITUTION:A liquid tank 1 is filled with photosensitive setting resin liquid 2. The light setting the photosensitive setting resin liquid 2 is emitted from the tip of the point light source such as an optical fiber. The point light source 3 is kept at the coordinates X-Y-Z crossing mutually at right angle, and the transferring control of the point light source 3 is achieved by the command from a figure treating device, using a positioning means. Because the set volume at setting point is controlled by the light intensity and its moving speed at the locus part to which the point light source 3 is transferred, the objective figure may be formed. Accordingly the generated product may be also seen floatably in the liquid tank, and further may be taken out from the tank, while extracting the unset portion of the photosensitive setting resin liquid.
