Device for forming solid shape

Abstract

Abstract PURPOSE:To form a solid shaped body having sufficient hardness by enlarging the degree of polymerization by a method wherein a plurality of times of light irradiation are performed at the predetermined time intervals to the same position of liquid photo-setting resin. CONSTITUTION:A plurality of laser beams 3a-3c, which are optically modulated by on-off action in accordance with the exposure pattern 2 in response to a shape to be set, are irradiated over liquid photo-setting resin 1 to selected positions. Three laser beams 3a-3c scan on the liquid photo-setting resin 1 along main scanning direction A, B and C so as to constitute 3 parallel scanning lines 3A-3C. The interval in the direction of auxiliary scanning direction of the three laser beams 3a-3c is L. After the end of irradiation in main scanning direction, the three laser beams 3a-3c are shifted in the auxiliary scanning direction by the distance of L so as to scan again in the main scanning direction. A plurality of times of exposure can be performed intermittently by exposing along a plurality of scanning lines in the main scanning direction with a plurality of laser beams and, after the shifting of the laser beams in the auxiliary scanning direction, scanning in the main scanning direction again.
