Abstract
A three-dimensional powder bed fusion additive manufacturing (PBF-AM) apparatus includes a movement mechanism, a stage, a plurality of support columns, a base plate, and a shielding member. The base plate is supported by the plurality of support columns, and a powder material for forming a product is laminated on the base plate. The shielding member surrounds the plurality of support columns between the stage and the base plate.
Claims17
A three-dimensional powder bed fusion additive manufacturing (PBF-AM) apparatus comprising:
- a movement mechanism;
- a stage that is movably supported by the movement mechanism;
- a build box with a cylinder hole in which the stage is arranged so as to be slidable;
- a plurality of support columns that are arranged on the stage;
- a base plate supported by the plurality of support columns, on which a powder material for forming a product is laminated;
- and
- a shielding member that surrounds the plurality of support columns between the stage and the base plate, and that forms a first space between the stage and the base plate,
- wherein a second space between the shielding member and an inner wall surface of the cylinder hole of the build box is filled with the powder material, and
- wherein the powder material is blocked by the shielding member, and the powder material is not present in the first space.
