Stressed? Relax with some two-photon lithography. 💥 This widely used 3D nanoprinting technique uses intense laser beams to harden a liquid into precise shapes. It is expected to be a game changer in manufacturing, but in order to become more widespread, the process has to become more reliable. LLNL researchers and collaborators are turning to machine learning to make two-photon lithography more controlled and feasible for wide use. New findings posted in the journal “Additive Manufacturing” sho
