U.S. Air Force Airman 1st Class Trevor Zucker, 1st Combat Communications Squadron radio frequency transmissions technician, prepares a 3D printer system by routing poly lactic acid filament through a filament feeder Nov. 19, 2020, on Ramstein Air Base, Germany. He demonstrated the 3D printer’s ability to produce some components that could be used as replacement parts in military systems. Zucker used the printer to create a mounting bracket for the quad-band large aperture antenna system because of the challenges in obtaining replacement brackets, preventing the satellite communications system from becoming non-mission capable.
