Powder bin for additive manufacturing system

Abstract:

A powder bin for an additive manufacturing apparatus has a plurality of walls forming an annular body to surround a build plate. The plurality of walls include an annular outer wall and an annular inner wall that are separated by a cavity, and a gap between a top edge of the inner wall and a top edge of the outer wall is configured to receive powder between the top edges of the outer walls and the inner walls. The annular body has an aperture that extends laterally through the inner wall and outer wall. A base is connected to a bottom edge of the outer wall and a bottom edge of the inner wall, and the base includes one or more ports. A sloped barrier is positioned in the cavity configured to direct powder around the aperture to the one or more ports in the base.
