Abstract
There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, a spatial light modulator that spatially modulates the light from the second light source and blanket-exposes a specified region of the resin, and an exposure position adjuster that moves, in at least one direction, the light from the spatial light modulator. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.
