Abstract
A lamination molding apparatus including a chamber covering a molding region; a laser beam source to emit a laser beam for sintering a material powder supplied on the molding region to form a sintered layer; and a scan unit to scan the laser beam. The laser beam has one or more spot shapes including at least an elongated shape, and the scan unit is configured to scan the laser beam, of which the spot shape is an elongated shape, in a lateral direction of the elongated shape, is provided.
Claims8
A lamination molding apparatus, comprising:
- a chamber covering a molding region;
- a laser beam source to emit a laser beam for sintering a material powder layer supplied on the molding region to form a sintered layer;
- an optical processing unit;
- and
- a scan unit to scan the laser beam, wherein:
- the optical processing unit comprises:
