Abstract
An optical molding apparatus is used for an optical molding method including the steps of radiating light onto a photocurable resin so as to cure the irradiated portion and laminating the cured objects. The apparatus comprises: a container provided with an aperture on a bottom surface or a side surface thereof; a base which is movably away from a surface of the aperture; a light radiation apparatus for radiating light into the container through the aperture; and a cured object holding plate which is freely mounted and dismounted from above the base. A movable base device for the optical molding apparatus comprises the base and an elevator erected on a peripheral edge of the container so as to lift and lower the base. The base is provided with a frame, one end thereof constituting a slide portion vertically moved along the elevator, a model holding plate removably mounted on the frame, frame supporting members with the base end sides thereof rotatably supported by the slide portion. The frame supporting members assume both a supporting state for supporting the frame when they are connected to the frame and an evacuated state when the connection is released and the free end sides are rotated upward.
