Ultralight, Ultrastiff 3D-Printed Material Can Hold Over 150,000 Times Its Own Weight

Lawrence Livermore National Laboratory (LLNL) and MIT researchers have created a material with the same weight and density as aerogel - a material so light it's called 'frozen smoke' - but with 10,000 times more stiffness. This material, which they developed using additive micro-manufacturing processes, could have a huge impact on the aerospace and automotive industries. "These lightweight materials can withstand a load of at least 160,000 times their own weight," says LLNL engineer Xiaoyu Zheng. "The key to this ultrahigh stiffness is that all the micro-structural elements in this material are designed to be over constrained and do not bend under applied load."?%9D The additive micro-manufacturing process involves using a micro-mirror display chip to create high-fidelity 3D parts one layer at a time from photosensitive feedstock materials. It allows the team to rapidly generate materials with complex 3D micro-scale geometries that are otherwise challenging or in some cases, impossible to fabricate.

It looks most useful for frameworks. Perhaps anything from components to skyscrapers. Steel buildings are able to be so tall and strong because of their lattice structure. This goes well beyond because each beam can be 3D micro printed. That would somewhat similar to animal skeletal structure with micro pores allowing much more strength per unit of mass. More efficient use of raw material for the same purpose and stronger. Wings for airplanes and bodies. Car panels could be much lighter and stronger at the same time. Perhaps surround the panels to seal them and fill them with helium? Or even a vacuum for reduced weight? I would like to learn more about this technology.
