The Exascale Additive Manufacturing (AM) project (ExaAM) is focused on metal AM process modeling at the fidelity of the microstructure. To date, ExaAM has instantiated exascale-ready continuum simulations of the AM build and melt-resolidification process during the laser scan. These continuum simulations are used to drive microstructure development simulations from which properties are calculated. Using the AMBench-01 problem as a test case, we generate an ensemble of microstructures and properties from which a continuum material model is determined. While potentially unique to the AMBench-01 build, this process-aware material model enables build simulations closer to AM conditions and part-scale qualification simulations in as-built material conditions. Comparison will be made to experiments of microstructure, properties and build. *Work performed under the auspices of the U.S. DOE by LLNL, LANL and ORNL under contracts DE-AC52-07NA27344, DE-AC52-06NA25396, DE-AC05-00OR22725, and supported by ECP (17-SC-20-SC), a collaborative effort of U.S. DOE Office of Science and NNSA.
