Abstract: A method for additively manufacturing a component includes generating, via imaging software, a plurality of slices of a support structure of the component based on component geometry. The method also includes melting or fusing, via the additive manufacturing system, layers of material to a build platform of the component so as to form the support structure according to the plurality of slices. The support structure includes a lattice configuration having of a plurality of support members arranged together to form a plurality of cells. Further, the method includes melting or fusing, via the additive manufacturing system, a component body to the support structure. After the component body solidifies, the method includes removing all of the support structure from the component body to form the component.

Abstract: A valve assembly and a method of additively manufacturing the same are provided. The valve assembly includes a valve housing defining first and second mounting features, such as recessed dimples or protruding bumps, positioned on opposite sides of a substantially cylindrical channel to define a hinge axis. One or more valve flaps are positioned within the cylindrical channel, each valve flap including a hinge member extending along the hinge axis and defining two or more complementary features or coupling members for engaging either the mounting features of the valve housing or an adjacent hinge member.

Abstract: A rotary actuator and a method of additively manufacturing the same are provided. The rotary actuator includes a valve housing defining a valve chamber and a shaft channel extending from the valve chamber. A valve body includes a valve shaft extending through the shaft channel and a valve head positioned within the valve chamber and defining a head width that is larger than the channel diameter to inseparably join the valve body and the valve housing. The valve head divides the valve chamber into a first chamber and a second chamber which are in fluid communication with a first port and a second port, respectively. The valve body is rotated by adjusting a fluid pressure within at least one of the first chamber and the second chamber.
