<p>The present invention relates to a DLP type 3D printer which comprises: a resin reservoir for storing a photocurable resin; a DLP projector disposed on a lower portion of the resin reservoir, for irradiating the resin reservoir with light corresponding to a cross-sectional image of an axial direction of an article to be molded; a molding stage configured to be capable of being lifted upward from the bottom of the reservoir, the lower portion of which accommodates an article being molded; a projector transfer unit for supporting the DLP projector such that the DLP projector moves in an X-axis direction and a Y-axis direction; an image processing unit for dividing one cross-sectional image of the article into a plurality of images to correspond to a plurality of molding regions to which the DLP projector is transferred by the projector transfer unit, and providing the divided images for the DLP projector; and a control unit for controlling the image processing unit, the projector transfer unit, and the molding stage to provide the divided images provided from the image processing unit for the molding regions to which the DLP projector is transferred, and to project the divided images provided for the DLP projector from each molding region to the resin reservoir.</p> |
