Abstract:
Provided is a 3-dimensional shaping device for manufacturing a 3-dimensional shaped object. The 3-dimensional shaping device comprises a beam emitting unit, a spatial optical modulator, separating optics, and a scan unit. The beam emitting unit emits a light beam. The spatial optical modulator spatially modulates the light beam emitted by the beam emitting unit in at least a first axis. The separating optics include at least one lens array having a plurality of lenses arranged along the first axis, and causes the light beam modulated by the spatial optical modulator to be separated by the lens array into a plurality of light beams.
