Paper Abstract

Additive manufacturing (AM) of metals is a rapidly growing advanced manufacturing paradigm that promises unparalleled flexibility in the production of parts with complex geometries. However, the extreme processing conditions create position-dependent microstructures, residual stresses, and properties that complicate certification. Quantitative modeling of these characteristics is critical, but model validation requires rigorous measurements including comprehensive in situ monitoring of the melt pool behavior, along with microstructure, residual stress, and property characterizations. Ideally, such benchmark measurements must be accepted broadly by the international AM community so that meaningful comparisons can be made. I will describe our establishment of the Additive Manufacturing Benchmark Test Series (AM-Bench), a continuing series of highly controlled benchmark measurements for additive manufacturing that modelers around the world are now using to test their simulations.
