The University of Maine has printed a 25-foot, 5,000-pound, fully seaworthy boat using the world’s largest 3D printer. The 70 feet long printer uses plastic polymer pellets to form the “ink” for printing. It consumes up to 500 pounds of it per hour. The boat was printed in one solid piece resulting from non-stop printing […]
