Innovation in Marine Corps: 3D printing in aviation
U.S. Marine Corps Sgt. Peter Jacobson, an aviation ordnance technician with Marine Fighter Attack Squadron (VMFA) 121, holds a 3-D printed infrared countermeasure (IRCM) bucket housing cover at Marine Corps Air Station Iwakuni, Japan, Aug. 13, 2018. Jacobson printed the cover to prevent corrosion in the IRCM bucket housing, a device designed to protect aircraft from infrared heat seeking missiles, in order to increase efficiency in the deployment of flares.
