Abstract: A method of partitioning a model to facilitate printing of the model on a 3D printer includes identifying partition sensitive locations on the model and creating a binary tree with a root note representative of the model. An iterative partitioning process is applied to divide the model into objects by selecting a node of the binary tree without any children nodes, identifying a portion of the model corresponding to the node, and determining candidate cutting planes on the portion of the model based on the partition sensitive locations. During the process, analytic hierarchical processing (AHP) is applied to select an optimal cutting plane from the candidate cutting planes based on partitioning criteria. The optimal cutting plane is used to segment the portion of the model into sub-portions, and two children nodes representative of these sub-portions are created on the node of the binary tree.

Abstract: Methods for automatic creation of workflows for design or simulation of a product to be manufactured and corresponding systems and computer-readable mediums. A method includes tracking a current workflow, by a data processing system, to produce current workflow data. The method includes converting the current workflow data into current workflow knowledge. The method includes predicting next actions for the current workflow, based on the current workflow knowledge and a contextual knowledge graph, to produce an automatically created workflow. The method includes implementing the automatically created workflow.

Abstract: Methods for hybrid manufacturing and planning and corresponding systems and computer-readable mediums. A method includes receiving, by a data processing system, a computer-aided-design (CAD) model of a part to be manufactured and tools definitions of tools available for a manufacturing process. The method includes instantiating a virtual workpiece. The method includes instantiating the tools definitions against a manufacturing ontology to produce virtual tools. The method includes receiving operations for the virtual tools. The method includes searching for combinations of the operations to be performed on the virtual workpiece to make the virtual workpiece correspond to the CAD model. The method includes identifying possible manufacturing solutions according to the search. The method includes selecting a manufacturing plan from the possible manufacturing solutions.

Abstract: A system and method is provided for modeling characteristics of a melt pool that forms during an additive manufacturing process. The system may include at least one processor configured to generate a data-driven model capable of predicting melt pool temperature and melt pool area for target deposit location points along at least one tool path for a three dimensional (3D) printer at which a laser of the 3D printer melts new deposits of material to buildup a product. The generation of the data-driven model may be based at least in part on melt pool temperatures and melt pool areas for a selected nearest subset of a plurality of previous deposit location points along the at least one tool path. The nearest subset may be selected based on determined spatio-temporal distance between a respective target deposit location point and each of the plurality of previous deposit location points along the at least one tool path.
