Abstract: A system for use in additively manufacturing an object. The system includes a powder bed configured for containment within a build chamber, wherein the powder bed is formed from a mixture of a build material and a bonding agent. The system also includes a heat source configured to selectively heat the powder bed to a temperature such that the build material is at least partially sintered together by the bonding agent. The heat source also selectively heats the powder bed to the temperature that maintains the build material in a solid state.

Abstract: A method for fabricating a component of with an additive manufacturing system include entraining a first portion of first material particles in an airflow generated by a vacuum source and engaging the first portion of the first material particles against an air permeable screen. The first portion of the first material particles is deposited onto a build platform. The method also includes entraining a second portion of second material particles in the airflow and engaging the second portion of the second material particles against the air permeable screen. The second portion of the second material particles is deposited onto the build platform. An energy source transfers heat to at least a portion of at least one of the first portion of the first material particles or the second portion of the second material particles to facilitate consolidating material particles to fabricate the component.

Abstract: A method of forming a composite component includes laying up a plurality of composite plies around a mandrel assembly to form a composite ply core. The mandrel assembly includes a mandrel having an inner structural body and an outer release layer. The mandrel is configured to form a cavity in the composite ply core. The method also includes processing the composite ply core containing the mandrel assembly to compact the plurality of composite plies together. Further, the method includes removing the mandrel assembly from the composite ply core to form the cavity. Further, removing the mandrel assembly from the composite ply core includes melting out the inner structural body and removing the outer release layer after melting out the inner structural body.

Abstract: An apparatus and method for rapid screening of material properties in a plurality of additively manufactured test specimens. The apparatus includes a build plate having the plurality of additively manufactured test specimens disposed on a first substantially planar surface. The plurality of additively manufactured test specimens are coupled to at least one actuator to one of individually or simultaneously translationally displace each of the test specimens along an axis “z”, and perpendicular to the build plane of the build plate to test material properties of each of the plurality of additively manufactured test specimens. A sensor is coupled to each of the plurality of additively manufactured test specimens. Load vs. displacement data may be used to monitor the progression of monotonic and/or cyclic tests of the plurality of additively manufactured test specimens.
