Lattice structures have been used in construction for hundreds of years. They're lightweight and low-density yet extremely strong and stiff, and 3D printing has proven itself to be capable of taking the typically large-scale structures down to a minuscule scale. Researchers at Lawrence Livermore National Laboratory (LLNL) have been working with 3D printed lattices a great deal, testing them for strength, creating super-strong microscopic structures, and even translating the structures into graphene aerogels. Now LLNL has published two new research papers that delve further into the miniaturization of lattice structures. Read more at 3DPrint.com: http://3dprint.com/170634/llnl-latti...es-3d-printed/
