In November 2016, when the Department of Defense (DOD) released its first Additive Manufacturing Roadmap, the document began with a sentence that has proven to be something of an understatement: “Additive manufacturing (AM), which includes the commonly used term ‘3D printing,’ is a rapidly growing and changing discipline.”
It’s been less than three years since then. While much of the world continues to think of AM technology as a convenient way to make sturdy plastic objects from 3D printers, military personnel at all levels have been pushing its limits far beyond what most imagined possible. Within that interval, these are just a few of the solutions produced by the military and its partners:
At the Oak Ridge National Laboratory, the Disruptive Technologies Laboratory of the Naval Surface Warfare Center produced the military’s first 3D-printed submarine hull, a 30-foot submersible hull inspired by the SEAL Delivery Vehicle. Compared to a traditional SEAL submarine hull, which costs up to $800,000 and takes three to five months to manufacture, the six carbon-fiber sections of the new prototype were built in four weeks and assembled at a cost of $60,000.
