Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G01B 3/14

US Classification:

33552, 33 1 BB, 33562

Abstract:

A component inspection system comprises a sensor apparatus and a template having a component side and an opposing inspection side. The inspection side includes a plurality of inspection bosses projecting therefrom, each of the plurality of inspection bosses having a first coupling and a sensor aperture. Each aperture is disposed axially through each respective boss to the component side of the template. The sensor apparatus includes a receptacle for retaining a sensor. The receptacle has a second coupling configured to individually engage with each of the plurality of first couplings for removably securing the sensor apparatus to a respective at least one of the plurality of inspection bosses.

Abstract:

An additively manufactured assembly including an additively manufactured component with an edge oriented with respect to a recoater blade direction and an non-contact support that does not form a part of the additively manufactured component, the additively manufactured support located adjacent the edge. A method of additively manufacturing a component includes additively manufacturing an component with an edge oriented with respect to a recoater blade direction simultaneous with additively manufacturing an non-contact support that does not form a part of the component, the additively manufactured support located adjacent the edge.

Abstract:

A system includes a build plate, at least one component that is additively manufactured on the build plate from a powder material, and at least one capsule that is additively manufactured on the build plate from the same powder material. The capsule includes an additively manufactured core that is representative of one or more scaled build configuration layers of the at least one component and an arrangement of the layers on the build plate, a sample of unused powder material, and a shell that at least partially encloses the core and the sample.

Christopher F. O'Neill - Marlborough CT, US

International Classification:

B22F 3/105

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.

B33Y 10/00
B33Y 30/00
B33Y 50/02

Abstract:

An additive manufacturing machine includes an energy unit with two energy beam sources, each with a different power level of energy beam. In addition, a build unit receives the energy beams, and a reflecting unit is positioned between the energy unit and the build unit and directs the energy beams. There is also an energy beam detector positioned on or near the build unit.

International Classification:

B33Y 80/00
F04D 29/54
F16B 5/00

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.

Inventors:

- Hartford CT, US
Christopher F. O'Neill - Hebron CT, US

International Classification:

B29C 67/00

Abstract:

An additive manufacturing process includes simultaneously constructing a component and a non-contacting thermal support for the component. The non-contacting thermal support includes a three dimensional negative of the component. The non-contacting thermal support transfers heat from the component into a heat sink.
