Zusammenfassung:	PURPOSE:To form a three-dimensional shape having a smooth surface at high velocity by performing irradiation of beams by a beam scanning part equipped with a first and second galvanomirrors and also performing it by both a vector scanning system and a raster scanning system and performing the scanning of an outline at every time when cured resin layers are formed by face scanning of one or a plurality of times. CONSTITUTION:Irradiation of beams 18 for the liquid surface 4a of a liquid photocuring type resin material 4 is performed by a beam scanning part 11 equipped with a beam oscillating means 17, an acoustic optical modulating means 21, a first galvanomirror 16 for deflecting beams in one rectilinear direction on a decomposition plane and a second galvanomirror 16' for deflecting beams in the direction orthogonal to the rectilinear direction. Further irradiation of beams is performed by two kinds of scanning which consists of both the outline scanning for scanning the lines of the outline of the decomposition plane by a vector scanning system and the face scanning for scanning the whole surface of the decomposition plane by a raster scanning system. The outline scanning is performed every time when the face scanning of one or a plurality of times is performed. Thereby the surface of the formed three-dimensional shape is made smooth and can be formed at high velocity.
