    Abstract: A modification of a topology optimization formulation for part-level generation is provided such that it includes additional constraints that ensure that the inertial quantities (e.g., COM, Mol, and mass) of an automatically generated part are equivalent to specified targets. These targets are the inertial values used in an initial assembly-level simulation. The reaction and external forces acting on the part of interest resulting from assembly-level simulation provide the boundary conditions used for part-level generation. By constraining the inertial properties in this way, there is no need to evaluate the assembly-level dynamics each time a part is generated.

    Abstract: The present disclosure provides techniques for analyzing trapped unused materials during AM. For example, given a geometry or shape to be manufactured using one or more AM materials, a tool path for solidifying the one or more AM materials is generated to turn the geometry into a physical object based on one or more manufacturing parameters related to AM resolutions. A processing device may compute a simulated manufactured geometry (e.g., a realistic representation of the actual shape of the corresponding physical object to be produced) based on the tool path and the one or more manufacturing parameters. The processing device analyzes the simulated manufactured geometry for a portion of removable AM materials trapped inside the simulated manufactured geometry. The processing device then generates a report regarding the portion of the removable AM materials trapped inside the simulated manufactured geometry.

    Abstract: The present disclosure provides techniques for automatically generating shapes (e.g., geometric representations) of two or more interacting objects based on arbitrary motions specified for the two or more interacting objects. In an example system. the system receives specifications of motions or movements of two or more objects and the associated design spaces and generates collision-free shapes for the two or more objects while the two or more objects undergo the specified motions. As such, the system solves for unknown or undefined shapes based on desired motion profiles. For example, given respective movement or motion characterizations of two or more objects, such as at least one of a function translation or a function rotation over time in at least one of the three axes in a Euclidean space, topology optimizations may be performed to generate the respective shapes or geometric representations of the two or more objects.

    Abstract: One embodiment of the present disclosure provides a system for determining a hybrid-manufacturing plan for manufacturing an object. During operation, the system can obtain a set of hybrid-manufacturing constraints for manufacturing the object. The set of hybrid-manufacturing constraints can include a set of primitives, a set of atoms, and an atom end-state vector. An atom can correspond to a unit of spatial volume of the object. A primitive can represent an additive or a subtractive manufacturing process corresponding to one or more atoms of the object. Next, the system can determine a plurality of feasible hybrid-manufacturing plans based on the set of hybrid-manufacturing constraints. Each feasible hybrid-manufacturing plan can represent an ordering of the set of primitives that satisfies the atom end-state vector. The system can then determine costs for manufacturing the object using the plurality feasible hybrid-manufacturing plans. The system can determine, based on the costs, an optimized hybrid-manufacturing plan for manufacturing the object.
