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.
