U.S. Air Force Staff Sgt. David Astleford, a 509th Maintenance Group research and engineering computer-aided drafting manager, showcases a 3D printed medical face shield prototype, made by the RE shop at Whiteman Air Force Base, Missouri, April 13, 2020. The RE shop utilized the National Institute of Health’s approved face mask as a model to create their own version of a face shield, featuring an added foam piece on the forehead to provide more comfort and using an adjustable band verses an elastic rubber one. Once approved, they plan on producing more than 300 shields to give to aid in Johnson County, Missouri’s COVID-19 medical efforts. (U.S. Air Force photo by Staff Sgt. Sadie Colbert)
