DefenceTalkDefenceTalkTiny, 3D printed cubes of plastic, with intricate fractal voids built into them, have proven to be effective at dissipating shockwaves, potentially leading to new types of lightweight armor and structural materials effective against explosions and impacts. “The goal of the work is to manipulate the wave interactions resulting from a shockwave,” said Dana Dattelbaum, […]https://www.defencetalk.com/shock-dissipating-fractal-cubes-could-forge-high-tech-armor-75888/

DefenceTalkArmy scientists are on the brink of a pioneering additive-manufacturing technology to help Soldiers quickly swap out broken plastic components with durable 3D printed replacements, says a top Army researcher. In the past, troops have either lugged replacement parts around or ordered them from warehouses thousands of miles away, only to wait weeks for them […]https://www.defencetalk.com/us-army-scientists-develop-cutting-edge-durable-3d-printing-technology-74154/
