MULTICHANNEL HEAD ASSEMBLY FOR THREE-DIMENSIONAL MODELING APPARATUS, HAVING POLYGON MIRROR ROTATING IN SINGLE DIRECTION, AND THREE-DIMENSIONAL MODELING APPARATUS USING SAME

摘要

The present invention relates to a multichannel head assembly for a three-dimensional modeling apparatus which can improve productivity by simultaneously or synchronously modeling a plurality of three-dimensional shaped objects having the same shape or different shapes, and a three-dimensional modeling apparatus using the same. The present invention provides a multichannel head assembly for a three-dimensional modeling apparatus, comprising: a modeling light source unit for allowing N modeling beams to be incident to a light guide unit; the light guide unit for receiving the N incident modeling beams and having a function of guiding each of the N modeling beams along a predetermined path so as to allow the N modeling beams to be incident to N modeling planes in one-to-one correspondence with each other; and a control unit for controlling driving of the modeling light source unit and driving of the light guide unit to be linked with each other, wherein a three-dimensional shaped object is modeled by scanning each of the N modeling beams with respect to one of the N modeling planes in a predetermined scanning pattern across the entire surface thereof.
