Direct Performance Evaluation of Additive Manufacturing Process Plans

Additive manufacturing is steadily advancing towards fulfilling its promise of customized and on-demand production of functional parts. However, performance of as-manufactured parts can differ significantly from the as-designed parts because the as-manufactured geometry differs from the as-designed geometry and the asmanufactured material properties are not known. Attempts to predict performance of as-manufactured parts are hampered by the complexity of the as-planned geometry and the unknown as-manufactured material properties.Intact Solutions proposes to demonstrate the feasibility of performing accurate structural simulation directly from additive manufacturing plans. This will be achieved by extending Intact Solutions’ moment-based interoperable simulation technology to incorporate material properties through a combination of analytical, experimental, and data-driven methods. The approach will be driven by manufacturing plans and available material information from NIST’s AMMD. A significant component of the proposed research is to utilize and improve the data fromthe AMMD in the next generation simulation technology that will support validation, planning, and optimization for additive manufacturing processes.
