The National Institute of Standards and Technology's (NIST) Material Measurement Laboratory's (MML) Additive Manufacturing Program (AM) studies the fundamental behaviors of materials under various conditions to produce reference standards that support U.S. commerce. These reference standards benefit U.S. manufacturing and competitiveness. The following are MML AM projects dedicated to the metrology of AM materials and several material types (metals, polymers, ceramics, & biomaterials). Feel free to contact us with questions or opportunities to collaborate.
