THREE DIMENSION PRINTING APPRATUS USING MASK FOR POSSIBLE ADJUSTING LIGHT TRANSMISSION REGIONS

摘要

The present invention relates to a three-dimensional printing apparatus using a mask which is allowed to control an optical transmittance area to be printed quickly by controlling the optical transmittance area on the mask on a real-time basis to be matched with a stored three-dimensional structure. In the present invention, a three-dimensional printing apparatus is allowed to print a predetermined three-dimensional structure by stacking a plurality of pattern layers on a supporting part, comprising: a raw material supplying part which supplies raw materials to the supporting part or on the pattern layers formed on the supporting part; an optical curable part which receives the supporting part with the raw material and selectively cures the raw material to be matched with the predetermined three-dimensional structure; a transferring part which transfers the supporting part between the raw material supplying part and the optical curable part; and a control part which controls the optical transmittance area of the optical curable part and accordingly sections the predetermined three dimensional structures into a plurality of layers to be matched with layers, thereby selectively curing the raw materials.
