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, medium, and system to receive an indication of an assembly including a plurality of different components to produce by additive manufacturing (AM), determine based on a forward search process that starts with individual components of the plurality of components and iteratively adds other components of the plurality of components thereto in combinations until an entirety of the assembly is accounted for, determine based on a reverse search process that starts with the entirety of the assembly and iteratively removes components of the plurality of components therefrom in combinations until a two-component set is reached, automatically select an optimal combination of the plurality of components from the combinations determined by the forward search and reverse search processes; and transmit the selection of the optimal combination of the plurality of components to an AM controller.

Abstract: A printing device receives modeling data that defines a three-dimensional solid model of a component body having a plurality of faces and a plurality of edges. Each of the faces meets another face of the component body at a respective edge of the component body. The printing device interrogates one or more faces of the component body to identify one or more looped geometries, and defines a lattice exclusion area having a boundary formed based at least in part on one or more faces of the component body that correspond to the looped geometries. The printing device generates a printer output of the component body and a lattice support structure for the component body. The printer output of the lattice support structure is outside of the lattice exclusion area.
