PURPOSE:To minimize the volume shrinkage at the time of curing photopolymerized resin in molding a three-dimensional model formed by using photopolymerized resin and improve further the finished shape accuracy without distortion. CONSTITUTION:Photopolymerized resin 1 is fed onto a transparent plate 2, and laser beam is emitted from an emission head 9 through the transparent plate 2 and photopolymerization is carried out. Solidified layers are fixed on a base plate 5, and said solidified layers are laminated successively on the base plate 5 by raising the Z-axis of the head 6. Shape control is carried out by shape scanning the emission head 9 by means of an NC control device 13, and processing to the photo-emission shape is performed. A supersonic vibration plate 7 is operated and the supersonic vibration is emitted during said photopolymerization curing to minimize the volume shrinkage at the time of curing cnd carry out molding high fished shape accuracy with little distortion. |
