Abstract
An optical shaping apparatus includes a first optical unit including a light modulation element that has a plurality of pixels and modulates light from a first light source for each pixel and irradiating modulation light from the light modulation element onto the photocurable resin through the light-transmissive portion, a second optical unit including a scanning member configured to deflect light from a second light source, the second optical unit being configured to irradiate scanning light from the scanning member onto the photocurable resin through the light-transmissive portion, the first and second optical units not including a common optical member, and a controller that controls the light modulation element and the scanning member so as to irradiate the modulation light onto a first resin area, and to irradiate the scanning light onto a second resin area in the photocurable resin.
