PURPOSE:To control to supply liquid photo-setting resin material uniformly with a predetermined thickness even though the viscosity of the liquid photo-setting type resin material is different by a method wherein a means to supply the resin material uniformly on the surface of the photo-setting type resin from a resin material supplying unit, in which a plurality of openings are arranged in one row in a predetermined direction. CONSTITUTION:Predetermined amount of liquid photo-setting type resin material 31 is supplied from the auxiliary scanning of a resin accommodating vessel 30 and the plurality of openings 34 of the resin material supplying unit 33, arranged with a distance (l) from the main scanning position of laser beams 22 whereby the supply of the liquid photo-setting resin material 31 from the plurality of openings 34 and exposure setting by the main scanning of the laser beams 22 are effected simultaneously in parallel substantially. Subsequently, the resin accommodating vessel 30 is descended by an auxiliary scanning table 32 by the size of the layer of resin material in which the supply and exposure setting of the liquid photo-setting type resin material 31 are effected and the resin accommodating vessel 30 is returned to a predetermined initial position, further, a level is adjusted so that the surface of next layer comes to the focus of ftheta lense 28 through a scan reflecting mirror 29. |
