Abstract
Official abstract text for this publication.
A lamination molding apparatus, including a chamber covering a molding region; a powder layer forming apparatus to form a material powder layer by discharging the material powder onto the molding region and planarizing the material powder on the molding region; a laser beam emitter to emit a laser beam for sintering the material powder to form a sintered body; a cutting machine to cut the sintered body; a horizontal drive device to move both the cutting machine and the powder layer forming apparatus in a horizontal direction parallel to the molding region; a first vertical drive device to reciprocate the cutting machine in a vertical direction orthogonal to the horizontal direction; and a second vertical drive device to reciprocate the powder layer forming apparatus in the vertical direction, is provided.
First claim
Opening claim text (preview).
What is claimed is: 1 . A lamination molding apparatus, comprising: a chamber covering a molding region; a powder layer forming apparatus to form a material powder layer by discharging the material powder onto the molding region and planarizing the material powder on the molding region; a laser beam emitter to emit a laser beam for sintering the material powder to form a sintered body; a cutting machine to cut the sintered body; a horizontal drive device to move both the cutting machine and the powder layer forming apparatus in a horizontal direction parallel to the molding region; a first vertical drive device to reciprocate the cutting machine in a vertical direction orthogonal to the horizontal direction; and a second vertical drive device to reciprocate the powder layer forming apparatus in the vertical direction. 2 . The apparatus of claim 1 , wherein when cutting the sintered body, the cutting machine is moved vertically downward and the powder layer forming apparatus is moved vertically upward to a position not interfering with the cutting. 3 . The apparatus of claim 1 , wherein the powder layer forming apparatus is configured to be capable of switching start and stop of discharge of the material powder. 4 . The apparatus of claim 3 , wherein the powder layer forming apparatus includes a material discharge unit for discharging the material powder into the molding region, a shutter for opening and closing the material discharge unit, and a shutter through-hole accommodating the shutter therein slidably. 5 . The apparatus of claim 1 , wherein the apparatus is configured to execute a molding cycle in which the material powder layer is formed and sintered with the laser beam, the molding cycle being executed for a plurality of local regions which are different each other in the molding region, adjacent two of the local regions in a same layer being partially overlapped each other.
