Abstract: A system may include a substrate stage, configured to support a substrate, where a main surface of the substrate defines a substrate plane. The system may include an ion source, including an extraction assembly that is oriented to direct an ion beam to the substrate along a trajectory defining a non-zero angle of incidence with respect to a perpendicular to the substrate plane. The system may include a radical source oriented to direct a radical beam to the substrate along a trajectory defining the non-zero angle of incidence with respect to a perpendicular to the substrate plane. The substrate stage may be further configured to scan the substrate along a first direction, lying with the substrate plane, while the main surface of the substrate is oriented within the substrate plane.

Abstract: An additive manufacturing system includes a platen to support an object to be fabricated, a dispenser assembly positioned above the platen, and an energy source configured to selectively fuse a layer of powder. The dispenser assembly includes a first dispenser, a second dispenser, and a drive system. The first dispenser delivers a first powder in a first linear region that extends along a first axis, and the second dispenser delivers a second powder in a second linear region that extends parallel to the first linear region and is offset from the first linear region along a second axis perpendicular to the first axis. The drive system a drive system moves the support with the first dispenser and second dispenser together along the second axis.

Abstract: Provided herein are approaches for increasing efficiency of ion sources. In some embodiments, an apparatus, such as an ion source, may include a chamber housing having a first end wall and a second end wall, and an extraction plate coupled to at least one of the first end wall and the second end wall. The extraction plate may include an extraction aperture. The apparatus may further include a tubular cathode extending between the first end wall and the second end wall.

Abstract: An additive manufacturing system that includes a platen, a feed material delivery system configured to deliver feed material to a location on the platen specified by a computer aided design program and a heat source configured to raise a temperature of the feed material simultaneously across all of the layer or across a region that extends across a width of the platen and scans the region across a length of the platen. The heat source can be an array of heat lamps, or a plasma source.
