Abstract: A system of manufacturing a component comprises forming a component on a conductive build plate. The component defines at least one access port and includes an inner surface that defines at least one internal passage. The system further includes forming at least one electrode within the at least one internal passage, wherein the at least one electrode is electrically isolated from the component. An electromotive force is applied to the at least one electrode to facilitate smoothing the inner surface.

Abstract: A method of fabricating a component is provided. The method includes depositing particles onto a build platform. The method also includes distributing the particles to form a build layer. The method further includes operating a consolidation device to consolidate a first plurality of particles along a scan path to form a component. The component includes a top surface spaced apart from the build platform and an outer surface. The outer surface extends between the build platform and the top surface, and at least a portion of the outer surface faces a substantially particle-free region of the build platform.

Abstract: An additive manufacturing system includes a laser device, a first scanning device, and an optical system. The laser device is configured to generate a laser beam, and the first scanning device is configured to selectively direct the laser beam across a powder bed. The laser beam generates a melt pool in the powder bed. The optical system includes an optical detector configured to detect electromagnetic radiation generated by the melt pool, and a second scanning device configured to direct electromagnetic radiation generated by the melt pool to the optical detector.

Abstract: In one aspect, an additive manufacturing system is provided. The additive manufacturing system includes a build platform, a first plurality of particles positioned on the build platform, and a particle containment system positioned on the build platform. The particle containment system includes a particle containment wall. The particle containment wall at least partially surrounds the first plurality of particles and includes a second plurality of particles consolidated together. The particle containment wall includes a top end spaced apart from the build platform, an inner face positioned against the first plurality of particles and extending between the build platform and the top end, and an outer face that faces a substantially particle-free region, the outer face positioned opposite the inner face and extending between the build platform and the top end.

Abstract: A method that includes additively manufacturing with an additive manufacturing (AM) system a sub-component that has a locator element. Using a control system of the AM system for positioning a first location of the locator element. Selectively placing a portion of another sub-component adjacent to the locator element, based on the positioning. Then attaching the second sub-component to the first sub-component in a region, wherein the region is based on the positioning knowledge from the control system so as to make a component. A component that comprises a first sub-component that has an AM locator element; and a second sub-component attached to the first sub-component, wherein the locator element is attached to the second sub-component within the same additive manufacturing build chamber as the first sub-component.
