NIST Researches Metal Additive Manufacturing Standards
The National Institute of Standards and Technology (NIST) is conducting important research to develop metrology tools and measurement standards for metal additive manufacturing (AM). Their goal is to enable confident use of metal AM in critical applications through methods focusing on materials science, measurement science, and data science.
Key Projects:
1. Fatigue and Fracture Critical Applications: NIST is researching methods to enable confident use of metal AM in fatigue and fracture critical applications through specialized R&D methods led by Nik Hrabe.
2. Additive Manufacturing of Metals (AMOM): This project enables new pathways for innovative materials design of additively manufactured metal alloys through a foundation of materials science, measurement science, and data science, led by Carelyn Campbell.
3. High Temperature Co-based Superalloys: NIST is researching the development of high temperature Co-based superalloys, new AM-optimized materials, and the optimization of currently used AM materials, also led by Carelyn Campbell.
4. Additive Manufacturing Benchmark Test Series (AM Bench): This provides a continuing series of AM benchmark measurements, challenge problems, and conferences to enable modelers to test their simulations against rigorous, highly controlled additive manufacturing benchmark measurement data, led by Lyle Levine.
NIST researchers are exploring new developments in metal AM, including understanding metal processes like metal 3D printing and distortion artifacts in printed parts. They collaborate with other research institutions to develop advanced measurement techniques and materials.
