Abstract
An optical molding apparatus molds a three-dimensional model by stacking cured layers. Each cured layer is formed by emitting light according to cross-sectional-shape data of the three-dimensional model onto a surface of photo-curable resin. The optical molding apparatus includes a container that contains the photo-curable resin, a movable stage that is movable in a direction orthogonal to the surface of the photo-curable resin, an optical system that emits the light onto the surface of the photo-curable resin contained in the container so as to form each cured layer on the movable stage, and a discharging mechanism that performs a discharging operation for discharging new photo-curable resin onto a surface of each cured layer formed on the movable stage before stacking a subsequent cured layer.
