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.

Abstract: An additive manufacturing apparatus includes an annular powder bin to surround a build plate, a support structure to hold the build plate in an interior of the powder bin, and a kinematic mount assembly for the support structure. The kinematic mount assembly includes at least three independently vertically kinematic mounts that support the support structure, and one or more actuators to independently control vertical motion of the kinematic mounts to control a tilt angle of the support structure and build plate.
