Two-photon lithography has advantages for precise additive manufacturing at the nanoscale, but its printing speed is currently too slow for large-scale practical applications. A sensitive photoresist based on zirconium oxide hybrid nanoparticles is shown to increase the linear printing speed of two-­photon lithography up to the order of metres per second.
