The NIST Additive Manufacturing Metrology Testbed is a fully custom, open-platform laser powder bed fusion (LBPF) system to advance monitoring, controls, and metrology research. In addition to research specific to AM, the system employs a suite radiometric calibration and measurement instruments that enable the Temperature and Emittance of Melts, Powders, and Solids (TEMPS). The AMMT/TEMPS is a collaborative development between NIST Engineering Laboratory (EL) and Physical Measurement Laboratory (PML) with shared metrology goals of traceable, multi-spectral radiometric measurements of laser-heated materials.

Example Capabilities and Measurements
NIST is open to collaborations on projects that can make use of the special capabilities of the AMMT. Unofficial collaborations are preferred, with topics that fall under the research goals of the AMMT and the Measurement Science for Additive Manufacturing Program, and any results can be made public and co-published by NIST. Official collaborations can be conducted through a Cooperative Research and Development Agreement (CRADA).
Want to work with the AMMT? Various opportunities exist for guest researchers, post-doctoral researcher associates, or for Ph.D. students through the NIST Pathways internship program.
