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: Additive manufactured components including portions having distinct porosities, and systems/methods of forming components including portions having distinct porosities are disclosed. The components may include a first portion having a first porosity. The first portion may include a first exposure pattern of a plurality of scan vectors extending over the first portion. The first exposure pattern may define the first porosity of the first portion. The component may also include a second portion positioned adjacent the first portion. The second portion may include a second porosity greater than the first porosity of the first portion. Additionally, the second portion may include a second exposure pattern of a plurality of scan vectors extending over the second portion. The second exposure pattern may be distinct from the first exposure pattern of the first portion, and may define the second porosity of the second portion.

Abstract: Additive manufactured components including sacrificial caps, and methods of forming components including sacrificial caps are disclosed. The additive manufactured components may include a body portion including a first surface, and a feature formed in the body portion. The feature may include an aperture formed through the first surface of the body portion. Additionally, the components may include a sacrificial cap formed integral with at least a portion of the first surface of the body portion. The sacrificial cap may include a conduit in fluid communication with the feature. The sacrificial cap including the conduit may be removed from the body portion to expose the first surface and the aperture of the feature, respectively, after performing one or more post-build processes, such as shot peening, on the component and the sacrificial cap.

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.

Abstract: In some cases, an additive manufacturing (AM) system includes: a process chamber for additively manufacturing a component, the process chamber having: a build platform; at least one melting beam scanner configured to emit a melting beam for melting powder on the build platform; an applicator for applying layers of powder to the build platform; and a reservoir for storing powder; and a control system coupled with the set of melting beam scanners, the control system configured to: apply the melting beam to a layer of powder on the build platform along a primary melting path; and apply the melting beam to the layer of powder on the build platform along a re-melting path after applying the melting beam along the primary melting path, the re-melting path overlapping a portion of the primary melting path and applied only in an area proximate a perimeter of the component.

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.
