One of 200 3-D printed face shields created by the 374th Maintenance Squadron Fabrications Flight prior to being distributed to the 374th Security Forces Squadron and 374th Medical Group to serve as an added layer of personnel protective equipment rests on a table at Yokota Air Base, Japan, April 3, 2020. Amid what is a worldwide shortage of PPE, these 3-D printed shields will increase the lifespan of other vital protective equipment, bolstering Yokota’s ability to protect its personnel and provide a safe, quality level of care to those that require medical assistance.
