Title:
METHOD FOR PRODUCING THREE-DIMENSIONAL SHAPED MOLDING
Document Type and Number:
Japanese Patent JP2008240075
Kind Code:
A
Abstract:

To provide a method for producing a three-dimensional shaped molding by which a metal powder material layer can be formed thinly.

A process where the prescribed part in the layer of a metal powder material P is irradiated with a light beam L, and the powder in the part is sintered, so as to form a sintered layer m, the new layer of the powder material P is formed on the surface of the sintered layer m, the prescribed part in the new layer of the powder material P is irradiated with a light beam L, and the powder material P in the part is sintered, so as to form a new sintered layer m integrated with the sintered layer m as the lower layer is repeated, thus a molding M with a three-dimensional shape in which a plurality of the sintered layers m are stacked and integrated is produced. At this time, before the new layer of the powder material P is formed on the surface of the sintered layer m as the lower layer, an adhesive g is scattered over the surface of the sintered layer m as the lower layer, and thereafter, the new layer of the powder material P is stacked on the surface of the sintered layer m over which the adhesive g is scattered.
