Excerpt: “And while nosing around on the larger topic of 3D printing, I found a story from this month in National Defense Magazine about the U.S. Army’s efforts to develop the world’s largest 3D printer that makes metal objects. The goal of the Jointless Hull Project is to create a printer large enough to produce the exterior of a combat vehicle in one piece. The machine will be able to print parts up to 30 feet long, 20 feet wide and 12 feet high. The lead contractor is ASTRO America, which says the technology will reduce costs, weight and production times for military vehicles while increasing “survivability.”
