A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a chemical delivery system, and a paddle assembly. The paddle assembly includes a rotatable drive shaft and a first plurality of paddles and a second plurality of paddles that extend radially from the drive shaft. The spacing, cross-sections, and oblique angles of the paddles are such that orbiting of the paddles causes the first plurality of paddles and the second plurality of paddles to displace substantially equal volumes in opposite directions in the lower portion of the stationary vacuum chamber.

An additive manufacturing apparatus includes a platform, a dispenser configured to deliver a plurality of successive layers of feed material onto the platform, at least one energy source to selectively fuse feed material in a layer on the platform, and an air knife assembly. The air knife assembly includes an inlet unit to deliver gas over the platform and an exhaust unit to receive gas from over the platform. The inlet unit includes a multi-chamber plenum, a gas inlet, and a gas distribution module. The multi-chamber plenum has a plurality of vertically stacked chambers that are fluidically connected, with a first chamber of the plurality of vertically stacked chambers positioned at a higher elevation than a collection chamber of the plurality of vertically stacked chambers.

An additive manufacturing apparatus includes an environmentally sealed first chamber, a second chamber separated from the first chamber by a first valve, a platform positionable in the first chamber, a dispenser configured to deliver a plurality of successive layers of feed material onto the platform in the first chamber, at least one energy source to selectively fuse feed material in a layer on the platform in the first chamber, and an air knife assembly to direct a laminar flow of air across a layer of feed material on the platform in the first chamber. The air knife assembly includes an inlet module and an exhaust module that are movable through the first valve between the first chamber and the second chamber.
