Military-focused drone manufacturer Firestorm says its xCell microfactory kept several HP MJF 3D printers busy aboard the USS Essex, producing more than 1,000 parts, including components for 12 Squall FPV drones, in waves reaching 12 feet on the way to RIMPAC, the multinational military exercise in Hawaii. Service members assembled the drones en route and later flew them in a counter-UAS exercise.
