| Abstract Scope |
Additive manufacturing (AM) is a transformative technology that enables customized production of parts with geometries that can be too costly, difficult, or in some cases, impossible to produce using traditional manufacturing processes. However, difficulties persist regarding throughput, reproducibility, reliability, and properties of the printed parts. Quantitative modeling is critical for mitigating these problems, but broad model validation requires community access to extensive benchmark test data. I will describe the Additive Manufacturing Benchmark Series (AM Bench) which provides rigorous measurement test data for validating AM simulations for a broad range of AM technologies and material systems. Through a collaboration encompassing nearly a hundred scientists from 11 NIST divisions and 19 external organizations, in 2022 AM Bench released nine large sets of metal and polymer AM benchmark data. Here, I will describe the AM Bench measurements and discuss how they fit into the context of qualification and certification of AM components. |
