Additive manufacturing presents extreme potential and concern for component design. The ability to spatially tailor processing conditions opens the door to sophisticated designs with heterogeneous materials. Accounting for heterogeneity, before exploiting it, requires the ability to link local processing state to performance of local material. A concern with current geometry-based design approaches, like topology optimization, is not directly accounting for material property changes with geometry updates. An AFRL program is currently working to address this challenge by generating highly-pedigreed data sets including detailed process descriptions, post-build characterization and mechanical testing. These data sets will be made available to the AM community in process-structure and structure-property material modeling challenge problems. Finally, challenge results will be used to feed novel model aggregation akin to weather forecasting strategies. Upon building these predictive engines, a follow-on program will focus on incorporating them into topology optimization frameworks. This talk will overview the two programs.
