NIST AM Bench Additive Manufacturing BenchmarkNew

Background

Metal powder-bed fusion is sold on "print it right the first time", yet simulation models of melt pools, residual stress and microstructure are rarely validated against measurements with known uncertainty. AM Bench closes that gap with standardized artifacts, controlled machines, and rigorous metrology.

What it provides

• Test artifacts spanning AMB2018-xx through AMB2022-xx and later challenge series
• Gold-standard measurements: in-situ melt pool imaging, X-ray CT, synchrotron diffraction, EBSD microstructure maps
• Blind prediction challenges: models run first, measurements released after

Where physics-AI enters

• Surrogates for melt-pool geometry and temperature history
• Learned microstructure-property linkages trained on EBSD maps
• Uncertainty quantification for residual-stress fields

Use cases

• Model developers: prove accuracy on a neutral, public benchmark
• Machine vendors: regression testing of process-parameter recommendations
• Researchers: training data for ML models of AM process physics
