PURPOSE:To constitute the title method so that a vacant hole part is not generated in a target-shaped body by preventing scattering of irradiating light, by a method wherein after removal of bubbles between a base surface and light transmitting window by sticking a base on, or close to, the light transmission window, light irradiation and base shifting are performed by separating the base from the light transmission window. CONSTITUTION:A base 21 is stuck on, or close to, a light transmission window 13 prior to shaping. Bubbles which have been kept stuck to the bottom of the base 21 or the top of the light transmission window 13 are removed through a space between the base 21 and light transmission window 13. After removal of the bubbles, a cured layer 24 of the first layer is formed by applying light to the layer by separating the base 21 from the light transmission window 13 by a fixed distance. Then after separation of the base 21 by the fixed distance further from the light transmission window 13, the light is applied to the layer and the cured layer 24 of the second layer is formed. The irradiating light is applied to photosetting resin and the photosetting resin flows into a space between the base and light transmission window. The bubbles are not taken into a cured matter of the photosetting resin. |
