Abstract
An optical shaping apparatus includes a light transmissive member, a shaping base, and a movement mechanism. The light transmissive member includes a regulation surface to regulate a liquid level of a photo-curable resin, and causes light used for curing the photo-curable resin to pass therethrough. The shaping base includes a support surface, a first end portion, and a second end portion, the support surface being opposed to the regulation surface and supporting a three-dimensionally shaped object that is formed by laminating the photo-curable resins cured by the light in a stepwise manner, the second end portion being on an opposite side of the first end portion. The movement mechanism moves the shaping base in a direction away from the light transmissive member so that the support surface is gradually moved away from the regulation surface from the first end portion side to the second end portion side.
