Abstract
An optical shaping apparatus includes: an exposing unit for turning on/off irradiation of light to a hardening resin surface for each predetermined unit area to irradiate light collectively on multiple the unit areas with irradiation of light being on; and a scanning unit for irradiating an optical beam with a predetermined diameter to scan the optical beam on the hardening resin surface; with the exposing unit irradiating the light in an area offset by a predetermined number of unit areas toward the inner side than the unit areas overlapped with the profile line of the cross-sectional-shaped data on the hardening resin surface; and with the scanning unit scanning an optical beam having a first diameter along a center line offset from the profile line of the cross-sectional-shaped data, and scanning an optical beam having a second diameter shorter than the first diameter along the inner side of the profile line.
