U.S. Air Force Airman 1st Class Cyrus Bartony, 18th Equipment Maintenance Squadron aircraft metals technology journeyman, prepares a 3D printed face shield to be printed through modeling software April 9, 2020, at Kadena Air Base, Japan. The 18th EMS modified the original design so the mask could be assembled with supplies that are commonly found. The intention is to make a how-to guide for hospitals to print their own supply of personal protective equipment. (U.S. Air Force photo by Airman 1st Class Mandy Foster)
