Boeing Microlattice: World's lightest metal is 99.99% hollow and the future of aeronautic design (James Billington, October 12, 2015, IB Times)
Aerospace manufacturer Boeing has created the world's lightest metal structure, which it claims is 99.99% hollow. The structure is so light that a sample can sit atop a dandelion. The revolutionary breakthrough claims to be 100 times lighter than Styrofoam and could be the future for aeronautical design.The material, called Microlattice, is a 3D open-cellular polymer structure and is inspired by bones where the outside is solid but on the inside you find a mostly hollow, yet extremely strong and light structure.
