Abstract: A powder processing machine includes a work bed, a powder deposition device operable to deposit powder in the work bed, at least one energy beam device operable to emit an energy beam with a variable beam power and direct the energy beam onto the work bed with a variable beam scan rate to melt and fuse regions of the powder, and a controller operable to dynamically control at least one of the beam power or the beam scan rate to change how the powder melts and fuses. The controller is configured to determine whether an instant set of process parameters falls within a defect condition or a non-defect condition and adjust at least one of the beam power or the beam scan rate responsive to the defect condition such that the instant set of process parameters falls within the non-defect condition.

Abstract: A method of obtaining a sample of materials includes building a product through an additive manufacturing process. A capsule is formed with an internal chamber inside of the capsule. The capsule is formed during the building of the additive manufacturing product. A sample of powder is encapsulated inside the internal chamber as the capsule is built. The internal chamber is hermetically sealed from an exterior environment to retain the sample of powder in the internal chamber.

Abstract: A structure includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.

Abstract: A method for operating an additive manufacturing apparatus, the method comprises directing a first energy beam along a surface contour vector in a build plane. A second energy beam is directed along a plurality of substantially parallel hatch vectors disposed in the build plane inward of the surface contour vector. A sum of the surface contour vector and the plurality of hatch vectors define a processed powder region in the build plane. A third energy beam is directed along an offset contour vector in the build plane. The offset contour vector includes a plurality of unprocessed powder regions in the build plane between the surface contour vector and the plurality of hatch vectors.
