Abstract: A computer program product comprising a non-transitory computer-readable medium storing instructions, that when executed by a computer processor, cause the computer processor to discretize distinct surfaces of a 3D model defining nominal geometry of a component to be manufactured using an additive manufacturing machine; define a build orientation of the 3D model, the build orientation comprises an initial build plane and a build direction; apply one or more in-plane offsets to at least one of the discretized distinct surfaces of the 3D model; and generate an offset 3D model for use by the additive manufacturing machine to manufacture the component such that a manufactured component comprises the nominal geometry defined by the 3D model, where the offset 3D model defines the nominal geometry of the component offset by the one or more in-plane offsets applied to the at least one of the discretized distinct surfaces of the 3D model.

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 method for additively manufacturing a component includes receiving, via an additive manufacturing system, a geometry of the component and melting and fusing, via an energy beam of the additive manufacturing system, material layer by layer atop a build platform according to the geometry so as to build up a plurality of layers that form the component. The method also includes determining a surface area change from one of the plurality of layers to the next based on the geometry. Further, the method includes temporarily discontinuing melting and fusing of the material by the energy beam between building of one or more of the plurality of layers so as to provide a delay after building one or more of the plurality of layers when the surface area change is above a predetermined threshold. As such, the delay allows for one or more previously built layers to at least partially cool so as to eliminate and/or reduce build failures from occurring in the final component.
