Abstract:
1. An optical shaping apparatus configured to irradiate light according to cross-sectional shape data of a three-dimensional model on a surface of a light hardening resin to form a hardening layer, and hardening layers to shape said three-dimensional model, comprising: one-shot exposing means for turning on/off irradiation of light onto the surface of said light hardening resin for each predetermined unit area, and irradiating light collectively on a plurality of said unit areas for which irradiation of light is on; scanning exposing means configured to irradiate an optical beam with a predetermined diameter, and scan said optical beam on the surface of said light hardening resin; a polarizing beam splitter configured to synthesize light from the one-shot exposing means and the optical beam from the scanning exposing means; and an objective lens to receive light from the one-shot exposing means and the optical beam from the polarizing beam splitter, the objective lens being configured to (a) image-form light from the one-shot exposing means on the surface of said light hardening resin and (b) condense the optical beam from the scanning exposing means, said objective lens receiving light from the one-shot exposing means before receiving the optical beam from the scanning exposing means, wherein,
