Abstract: An additive manufacturing system includes a build platform, a plurality of particles positioned on the build platform defining a build layer, a first and second region within the build layer, and at least one consolidation device. The first region and the second region each including a portion of the plurality of particles. The at least one consolidation device is configured to consolidate the plurality of particles within the build layer into a solid, consolidated portion of said build layer. The consolidation device is further configured to consolidate at least one of the plurality of particles within the build layer and the solid, consolidated portion of the build layer into a molten volume of transfer material. The consolidation device is further configured to transfer a portion of the molten volume of transfer material within the first region from the first region to the second region.

Abstract: A manufactured article is comprised of an additively manufactured component having sequentially joined layers of metallic powder. A braze material is disposed on at least a portion of an outer surface of the component. The braze material is located in expected crack locations in the outer surface. At least one crack formed in the outer surface, during a heat treatment, is filled with the braze material. The additively manufactured component comprises a metallic material from a precipitation hardened nickel-based superalloy, which forms a γ′ phase.

Abstract: An additive manufacturing system includes a laser device, a build plate, and a scanning device. The laser device is configured to generate a laser beam with a variable intensity. The build plate is configured to support a powdered build material. The scanning device is configured to selectively direct the laser beam across the powdered build material to generate a melt pool on the build plate. The scanning device is configured to oscillate a spatial position of the laser beam while the laser device is configured to simultaneously modulate the intensity of the laser beam to thermally control the melt pool.

Abstract: Controlling microstructure in an object created by metal powder additive manufacturing is disclosed. During additive manufacturing of one or more objects using an irradiation beam source system, for each respective layer in a selected range of layers including a cross-sectional area of the one or more objects including the selected object, a duration controller controls actuation of each irradiation device to maintain constant a sum of: an irradiation device melting time, an irradiation device idle time, and a recoating time expended applying a new powder material layer, while otherwise maintaining all other operation parameters of each irradiation device constant.
