Traditional planar litography districtres structures to essentially 2.5D (thin films with vertical etching). In contrast, two-photon polimization and self-assembly can create true 3D geometries - overhangs, hollow channels, curved surfaces, and hierrachchical structures. These are game-changing for photonic crystals, micro-lattics wigh negative Poisson 's ratio, and micro-fluidic mixers.
