Abstract: A method includes assembling a setter assembly onto a binder-jet printed part, wherein the setter assembly includes a base, a top setter, a bottom setter positioned between the base and the top setter, and a support pin extending between the base and the top setter having a terminus that abuts an inward facing surface of the top setter, such that at least portion of the binder-jet printed part is nested between the top setter and the bottom setter. The method includes heating the binder-jet printed part and the setter assembly to debind or sinter the binder-jet printed part, wherein a length of the support pin decreases in response to the heating to move the top setter toward the base.

Abstract: An airfoil for use in a turbomachine includes a pressure sidewall and a suction sidewall coupled to the pressure sidewall. The suction sidewall and the pressure sidewall define a leading edge and a trailing edge, the leading edge and the trailing edge define a chord distance. The airfoil includes a tip portion extending between the pressure sidewall and the suction sidewall. The tip portion includes a planar section and a recessed section. The recessed section extends adjacent to the planar section such that a thickness of the planar section is less than a thickness of the airfoil. The recessed section is offset a predetermined distance from the leading edge and the trailing edge along the chord distance.

Abstract: A method of generating a distortion-compensated geometry for a workpiece includes generating a green body part geometry for the workpiece, discretizing the green body part geometry into a green body part mesh and performing a first sintering analysis on the green body part mesh to generate a post-sintering mesh based on the green body part mesh, the post-sintering mesh including a plurality of post-sintering mesh nodes. The method also includes co-registering the post-sintering mesh and a model mesh having a geometry corresponding to the three-dimensional model, the model mesh including a plurality of model mesh nodes. For each of the plurality of post-sintering mesh nodes, a displacement between a post-sintering mesh node and a corresponding model mesh nodes is determined, and the green body mesh may be adjusted based on the displacement to generate the distortion-compensated geometry.

Abstract: A method and system to receive a specification defining a model of a part to be produced by an additive manufacturing (AM) process; define a design space to enclose the part and a support structure for the part, the support structure to support the part and printed with the part during the AM process; execute an iterative topology optimization(TO) based at least in part on the specification for the part and the defined design space, to generate a TO support structure that counteracts predicted gravity-based distortions during the AM process; save a record of the generated TO support structure; and transmit the record of the TO support structure to an AM controller, the AM controller to control an AM system to generate an instance of the part and the TO support structure based on the record.

Abstract: The present disclosure is directed to a shroud assembly for a gas turbine. The shroud assembly includes a casing and a shroud. The shroud includes a radially outer wall engaged with the casing. A radially inner wall integrally couples to the radially outer wall. The radially inner wall and the radially outer wall collectively define a pair of axially opposed cavities. The radially inner wall moves radially outward toward the casing when one or more gas turbine blades contact the radially inner wall.
