“WASHINGTON ― A U.S. Marine Corps pilot has successfully flown an F-35B Lightning II with a 3-D printed part. The Marine Fighter Attack Squadron 121
used 3-D printing to replace a worn bumper on the landing gear of the fighter jet.
As a commander,
my most important commodity is time,” according to Marine Corps Lt. Col. Richard Rusnok, the squadron’s commanding officer.
“Although our supply personnel and logisticians do an outstanding job getting us parts, being able to
rapidly make our own parts is a huge advantage.”
