Additive Manufacturing Benchmarks 2018 (AM-Bench 2018) is the first in a series of events focused on validating and improving the accuracy of model predictions and developing universally accepted quantitative measurement approaches for all additive manufacturing (AM) materials and methods. By addressing a critical barrier to widespread adoption of AM solutions, the AM-Bench measurements and associated conference series will make a significant impact on the global additive manufacturing community. AM researchers, practitioners, end-users, modelers, and vendors are invited to contribute to the outcomes of AM-Bench 2018 by presenting their latest work as part of the AM-Bench 2018 Benchmark Measurement and Modeling Symposium, participating in the AM-Bench 2018 benchmark challenges, or attending AM-Bench 2018 to learn about the current state-of-the-art measurements and models, provide input into future benchmark tests, and network with customers and AM experts. AM-Bench 2018 is sponsore
