Researchers report the fabrication of materials consisting of nanoscale carbon beam lattices, using a combination of 3D printing and high-temperature pyrolysis; the process yielded narrower beams than the resolution limits of conventional 3D printing, and the resulting materials were lighter than water, could be made virtually insensitive to fabrication-induced defects, and were stronger relative to their density than any existing microarchitected or nanoarchitected materials, with strengths approaching the theoretical limit.
