Title: THREE-DIMENSIONAL PRINTING APPARATUS AND METHOD FOR PRODUCING THREE-DIMENSIONAL PRINTED OBJECT
Abstract:
A three-dimensional printing apparatus is provided with: a powder layer-forming unit (120) for forming a powder layer made of a powder material on a printing stage (110); a laser-irradiating unit (130) for irradiating a laser on the printing region of the powder layer to sinter or melt-solidify the printing region and form a printed layer; a heat-dissipating material-supplying unit (123) for supplying heat-dissipating material on the printing stage (110); and a control unit (150) for controlling the powder layer-forming unit (120), the heat-dissipating material-supplying unit (123) and the laser-irradiating unit (130) to repeat the processes of disposing the heat-dissipating material while forming powder layers and printed layers and laminate multiple printed layers so that at least a portion has the heat-dissipating material disposed therearound.
