Abstract: A gas manifold for single-nozzle deposition chambers comprising a base having a top surface and bottom surface defining a thickness; a primary nozzle having an inlet and outlet extending through the thickness of the base; and a secondary nozzle having an inlet extending partially through the top surface of the base and at least one channel extending a distance from a sidewall of the base having an outlet, the channel in fluid communication with the inlet of the secondary nozzle. The inlet of the primary nozzle has a hollow protrusion extending from the top surface of the base into the gas feed. The channel of the secondary nozzle includes a bend between the sidewall of the base and the outlet configured to pass between a first direct energy source and second direct energy source, the first energy source and second energy source disposed on a top wall of a chamber.

Abstract: An additive manufacturing (AM) system includes a build chamber, a base adjustably coupled to the build chamber, and a build material applicator for depositing a build material above a build platform for creating the object. The build platform includes a fixed region fixedly and rigidly coupled to the base and a flex region configured to flex relative to the base in response to a force applied to the build platform by an object. The partial flexibility allows deformation caused by thermal distortion of the build platform during use to reduce final object stress. The AM system can produce larger additively manufactured objects out of crack-prone material. In addition, the partial flexibility may prevent damage to the build platform and/or base without an overly complicated arrangement.

Abstract: An additive manufacturing system includes an additive manufacturing unit that includes a housing for additively processing a powder material along a build direction into a build assembly. The additive manufacturing system further includes a rotator assembly for rotating the build assembly within the housing. The rotator assembly includes a frame including a first frame arm and a second frame arm and a carriage rotatably coupled to the first frame arm and to the second frame arm. The carriage includes at least one coupling mechanism for removably coupling the carriage to the build assembly. The rotator assembly further includes a drive assembly coupled to the carriage for selectively rotating the carriage about a rotational axis that is generally perpendicular to the build direction.
