A research group at Lawrence Livermore National Laboratory has produced ultrastiff ultralowdensity metamaterials by 3D printing of microarchitected microlattices. This is very cool – they do additive 3D printing using microstereolithography with nanocoating and postprocessing and can make self-similar lattices with densities varying by several orders of magnitude in bulk density but near constant stiffness.…
