PHOTOFABRICATION APPARATUS AND PHOTOFABRICATION METHOD

摘要

PROBLEM TO BE SOLVED: To shorten a shaping time to enhance productivity.;SOLUTION: After the surface of a shaping surface 5 is irradiated with light through a planar drawing mask 3 having a predetermined pattern to form a photocured layer 9 of one layer, a new shaping surface 5 is formed on the surface of the photocured layer 9 and irradiated with light through the planer drawing mask 3 to laminate and form a new photocured layer 9. In this optical shaping apparatus 100 for forming a three-dimensional shaped product by repeating this photofabrication process, a first process for forming the photocured layer 9 of one layer for irradiating an exposure surface with light while reciprocally moving the same on the surface of the shaping surface 5 to form the photocured layer 9 of one layer and a second process for irradiating the exposure surface with light while moving the same along the pattern 8 to be formed on the shaping surface 5 to form the photocured layer 9 of one layer are changed over corresponding to the pattern 8 to be formed on the shaping surface 5.;COPYRIGHT: (C)2006,JPO&NCIPI
