Abstract
An optically shaping apparatus includes a light modulation element having a plurality of pixels and configured to modulate light from a light source for each pixel, an optical system configured to irradiate modulation light from the light modulation element onto the photocurable resin through the light-transmissive portion, a controller configured to control the light modulation element based on each of a plurality of two-dimensional shape data corresponding to a plurality of sections in a three-dimensional object, and a moving member configured to move a cured portion cured by the modulation light among the photocurable resin in a direction separating from the light-transmissive portion. The controller controls an irradiation timing of the modulation light onto the photocurable resin for each pixel to form the cured portion corresponding to the same section in the three-dimensional object, in accordance with information on a shape of the light-transmissive portion.
