Abstract: A method of making a part includes creating a computer file defining the part in layers and a model of a body blank to represent a space defined by a cavity in the part. The part is built using an additive manufacturing process. A layer of powdered material is deposited into a powder bed. The powder bed is preheated by applying a first beam current with a first energy. A second beam current with a second energy level greater than the first energy level is applied to a first region of the layer of the powder bed not including a portion of the cavity. A second region of the powdered material is selectively melted. The partially built part and layer of the powdered material are lowered. Steps are repeated for additional layers in accordance with the computer file to create the part.

Abstract: A method of forming a metal component with two and three dimensional internal functionally graded alloy composition gradients includes forming the component by a powder based layer-by-layer additive manufacturing process. The areal composition distribution of each powder layer is determined by simultaneously depositing different powders and powder mixtures through a mixing valve attached to a single nozzle during powder deposition. The layers are then sintered with a directed energy source to form a forging preform. The preform is then forged to form a component.

Abstract: An assembly for use in an attritable engine includes a hub and a blade. The hub is configured to rotate about a centerline axis passing through a center of the hub and is formed with a first type of layer-by-layer additive manufacturing process. The blade is connected to and extends radially outward from the hub. The blade is formed with a second type of layer-by-layer additive manufacturing process that is different than the first layer-by-layer additive manufacturing process. The hub and the blade are integrally formed together as a single piece of material with a layer-by-layer additive manufacturing process. The blade includes a root of a first material, a platform connected to the root, an airfoil connected to and extending from the platform, and a tip connected on a distal end of the airfoil opposite from the root. The platform includes a material that is different from the first.
