DOVER, Del. (AP) — Delaware's Dover Air Force Base is using 3D printers to make face shields to protect against the spread of the coronavirus. The U.S. Air Force said in a press release on Thursday that more than 70 face shields were printed by a team of airmen at its innovation lab.

The lab, known as BEDROCK, can produce up to 20 face shields each day. The shields are made of a plastic that's chemically resistant and reusable. The shields include a thin plastic visor as well as an elastic headband.

Master Sgt. Justin Pittman said that the team making the shields "functions like a well-oiled machine."
