Abstract:
1. An optical shaping apparatus, comprising: a light transmissive member that 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; a shaping base that includes a first end portion, and a second end portion, the shaping base including a first member and a second member that includes a support surface and is rotatably coupled with a hinge member to the first member on the first end portion side, the support surface being opposed to the regulation surface and being operable to support 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, said shaping base including an elastic member to couple the first member and the second member on the second end portion side; and a movement mechanism to move 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.
