Abstract:
A method of forming a complex shaped part includes the steps of forming a polymer core by an additive manufacturing process. A metal is plated about surfaces of the polymer core, and the polymer core is removed, leaving hollows within a plate core. Metal powder is deposited within the hollows. An integral blade rotor is also disclosed.
Abstract:
An abradable seal for a gas turbine engine includes a seal body that has a seal side and a non-seal side. The seal body includes an abradability characteristic that varies by locality.
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:
The invention relates to an additive manufacturing apparatus and method. According to the invention, an additive manufacturing apparatus includes a material supply system. The material supply system delivers layers of partially sintered pulverant material to an additive manufacturing device.

Abstract:
A turbine engine component includes a surface to be cooled by a flow of cooling air and a plurality of pedestals projecting from the surface to be cooled. At least one of the pedestals includes a pedestal surface oriented such that a ray normal to the pedestal surface and directed away from the pedestal surface intersects a line defined by an intersection between the surface to be cooled and the pedestal.
Abstract:
A component includes a support structure made with an additive manufacturing process with a first end and a second end, and an object made with an additive manufacturing process with a first end and a second end, where the first end of the object is attached to the second end of the support structure. A cross-sectional area of the first end of the object is larger than a cross-sectional area of the second end of the support structure. A method of making an object, the method includes manufacturing a support structure with an additive manufacturing process. An object is manufactured on top of and connected to the support structure with an additive manufacturing process, wherein there is a witness mark created between the support structure and the object. The witness mark is identified. The object is separated from the support structure along the witness mark.
Abstract:
An additive manufacturing apparatus is disclosed which includes a movable platform. The movable platform has a plurality of fasteners and an upper surface, and at least one indexing feature. An upper surface of a movable platform is coupled with an indexing device such that movement of either one corresponds to movement of the other. The indexing device is capable of receiving a compatible indexing device from a manufacturing
