MIT just dropped a game-changer: a 3D-printed aluminum alloy that’s FIVE times stronger than regular aluminum and can handle extreme heat. Imagine lighter, tougher airplane engines, eco-friendly cars, and more energy-efficient tech—all thanks to this wild new metal. The secret? Super tiny patterns inside the alloy, made possible by rapid 3D printing. Could this be the future of sustainable manufacturing? Would you trust a 3D-printed home in a disaster? #Science #MIT #3DPrinting
