Sub $400 3D prints electric sensing temporary tattoos for soldiers

Scientists at the University of Minnesota (UMN) have 3D printed an electronic circuit on to the back of a human hand for the first time. Though temporary, like lick n stick tattoos, this technology presents great potential for helping to heal wounds, gather advanced intelligence on the battlefield, and promote response in remote locations. “It would […]

GE completes testing of 3D printed Black Hawk Turboshaft engine

Emerging from six months in the U.S. Army’s Improved Turbine Engine Program (ITEP), GE Aviation’s T901 Turboshaft engine has successfully completed prototype testing. The engine has been made using a range of additively manufactured parts, and is now ready to enter the next phase of development. Ron Hutter, executive director of the T901 program, comments, “We’re thrilled […]

Royal Navy unveils 3D printed “Nautilus 100” mothership concept

Earlier this year, the Royal Navy ran the Nautilus 100 challenge together with UK Nest, a not-for-profit Technology forum that “promotes the Engineering, Science and Technology interests of UK Naval Defense”. Scientists, designers, and engineers from across defense and aerospace sectors were tasked with envisioning the future of underwater warfare. 20 participants, aged between 16 […]

U.S. Army seeks commercialization of 3D printed cement barracks

Ordered, concrete, and spanning 512 square-feet, the Construction Engineering Research Laboratory (CERL) in Champaign, Illinois, has revealed the successful construction of its first 3D printed barracks hut. The B-Hut is a product of the lab’s Automated Construction of Expeditionary Structures (ACES) project, that is now seeking commercialization with a North American industrial corporation. Expeditionary structures on-demand The semipermanent […]

Army Looks Beyond 3D Printing, Explores 4D Technology

(Gizmodo) The military has begun employing 3D printing to make spare parts and components and now the Army is exploring 4D printing, the next generation. 4D printing adds transformation dimension to 3D printing. The idea is that a 3D printed component’s properties could be altered when exposed to environmental factors such as water or extreme temperatures. Body armor is one possible future application of 4D printing. The Army has struggled over the past decade with the need for field armor that is both protective and light enough not to burden the soldier or restrict movement. Using 4D printing, scientists could one day develop lightweight, compact body armor that is easy to store and carry, but can expand and offer full coverage. That kind of technology, however, is still years down the road. The Army is currently focusing on developing materials for 4D printing and it will have to study how best to manufacture components.
