Optical molding apparatus and movable base device therefor.

摘要

An optical molding apparatus 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 comprising: a container for accommodating the photocurable resin provided with an aperture on the bottom surface or a side surface thereof; a light radiation apparatus for radiating light into the container through the aperture; and a base provided in the container in such a manner as to be movable away from the aperture; wherein the surface of the base on the side of the aperture has a better adhesion with a cured object than the surface of the aperture on the inner wall side of the container. An optical molding apparatus 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 comprising: a container provided with an aperture on the bottom surface or a side surface thereof; a base which is movable away from the surface of the aperture on the inner wall side 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 an optical molding apparatus 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 device comprising: a base provided in such a manner as to face an aperture provided on the bottom surface of a container for accommodating the photocurable resin; and an elevator erected on the peripheral edge of the container so as to lift and lower the base. The base is supported by the elevator in a cantilever state. The base is provided with a frame one end thereof constitutes 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 and the free end sides thereof being vertically rotatable. The supporting members fall down on the frame. 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.
