Abstract
Disclosed is an additive manufacturing apparatus. The apparatus includes a residual powder chamber with a receiving opening to receive excess powdered material. A region between the construction area and the receiving opening has at least one flow restricting device. A region between a construction area of the apparatus and the residual powder chamber and/or at least a part of the residual powder chamber is preferably covered by at least one cover element leaving the receiving opening free. The surface of the cover element least one flow restricting device for the powdered construction material.
Claims17
An apparatus for the additive manufacture of manufacturing products by consecutive selective consolidation of layers of a powdered construction material which can be consolidated at positions which correspond to a cross section of the manufacturing product, having:
- at least one construction container comprising at least one height-adjustable construction platform,
- at least one consolidation device for consolidating construction material to be consolidated in a construction area above the construction platform,
- at least one coater, wherein the coater is configured to apply layers of the construction material to the construction platform and/or to a previously applied layer,
- and
- at least one residual powder chamber with a receiving opening for receiving surplus powdered material displaced by the coater,
- wherein a region between the construction area and the receiving opening has at least one flow inhibiting device for the powdered material.
A method for the additive manufacture of manufacturing products by consecutive selective consolidation of layers of a powdered construction material which can be consolidated at positions which correspond to a cross section of the manufacturing product, in an apparatus having:
- at least one construction container comprising at least one height-adjustable construction platform,
- at least one consolidation device for consolidating construction material to be consolidated on the construction platform,
- at least one coater, wherein the coater is configured to apply layers of the construction material to the construction platform or to a previously applied layer,
- and
- at least one residual powder chamber with a receiving opening for receiving surplus powdered material displaced by the coater,
- wherein a flow of the powdered material is inhibited in a region between the construction platform and the receiving opening.
