PURPOSE:To make the layer thickness of photosetting layers uniform and enhance appearance quality by forming a light reflecting layer on the surface of the photosetting layer, supplying photosetting resin of said light reflecting layer, and then irradiating said photosetting resin with light and forming a photosetting layer for a following layer. CONSTITUTION:A light beam 3 for setting having a focus in the vicinity of liquid surface provided with given radiant energy and transmission depth is irradiated between a molding bed 5 sunk in a resin liquid tank and the liquid surface by means of a beam condensing lens 30. Resin liquid 2 irradiated with the light beam 3 for setting is fed to form a photosetting layer 40 of given pattern. Then, a beam reflection material 70 is moved from the side of a resin liquid tank upward to the center of the same, and a beam reflection material 60 is sprayed from a spraying nozzle 71 or to the surface of the formed photosetting layer 40 to form a beam reflection layer 6. Then, a molding bed 5 is lowered to sink the formed photosetting layer 40 into the resin liquid 2, and then new resin liquid 2 is fed onto the photosetting layer 40, and then the light beam 3 is again irradiated to form another photosetting layer 40, and thus the new photosetting layer 40 is laminated on the previously formed photosetting layer 40. |
