METHOD FOR FORMING THREE-DIMENSIONAL CONFIGURATION

摘要

PURPOSE:To prevent the undulation generated on the surface of a photo-setting resin solution by irradiating the photo-setting resin solution with light in such a state that the surface of said resin solution is pressurized to form a photo-set layer and stacking said photo-set layer over a plurality of layers. CONSTITUTION:Piping for supplying inert gas and pressurizing a photo-setting resin solution is connected to the side wall adjacent to the hermetically closed space 7 of a resin solution tank 1 and also connected to the supply source of the inert gas such as nitrogen or argon and a pressure device such as a compressor. The inert gas pressurized to definite pressure is supplied to the hermetically closed space 7 to be brought into contact with the surface of the photo-setting resin solution 2. In this state, the photosetting resin solution 2 is irradiated with laser beam 3 corresponding to a three-dimensional configuration to be formed to form a photo-set layer 40. Next, a molding stand 50 is allowed to fall to cover the photo-set layer 40 with the new resin solution and the laser beam 3 is again applied to said photo-set layer. This cycle is repeated.
