Abstract
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 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.
