Inside the Pentagon’s 3D Printing Revolution — and the Rising Geopolitical Storms It Must Navigate The U.S. Army is no longer just a warfighting machine — it’s becoming a mobile, self-sustaining, on-demand manufacturing force, powered by 3D printing, artificial intelligence, and next-gen drone delivery. But as military modernization accelerates, so too do the geopolitical threats […]

Scientists have created a robotic quad-copter that can extrude polyurethane foam while in flight. By targeting where that foam goes, it can build up simple structures, essentially becoming a flying 3D printer. The technology could have some very important applications.
