| Abstract Scope |
This talk describes the planning and execution of the IN718 three-dimensional builds of bridge-structure parts conducted on the Additive Manufacturing Metrology Testbed (AMMT) at NIST for the AMB2022-01 and -02 challenge sets. The AMMT is first introduced, including background on the fully custom laser-galvo control capabilities, and newly upgraded high-speed in-situ thermographic melt pool measurement system. The machine parameters and scan strategies for fabricated bridge structures are then detailed, including custom-designed laser scan strategies. The analysis and results from in-situ thermographic measurements are then detailed, including thermal calibration procedures, and derivation of ‘time above melt’ and ‘cooling rate’ data features from the high-speed thermal video. Finally, details are provided on the compilation, access, and use of the voluminous scan strategy and in-situ measurement datasets are provided. |
