NIST Director, Dr. Willie E. May, welcomed students from Poolesville High School in Poolesville, MD, James Hubert Blake High School in Silver Spring, MD and Montgomery College, after which Dr. Joannie Chin led the students in an interactive manufacturing-related trivia game. Students then broke into groups to tour the NIST robots for manufacturing testbed, million pound deadweight machine, 3-D printing lab and the newly opened digital thread testbed. Shown here are photos taken during the opening activities as well as at the 3-D printing lab and digital thread testbed.
