Abstract
We review our recent progress on laser-based 3D micro- and nanoprinting, including application examples, on (i) multi-material, and (ii) faster/scalable 3D printing. Regarding (i), we report on combining self-organization and 3D printing for light-scattering devices, stimuli-responsive liquid-crystal elastomer photoresists, and 3D polymer-metal architectures. Concerning (ii), we present a novel 3D chiral mechanical metamaterial with tailored characteristic length, composed of nearly 120 thousand complex unit cells, enabled by rapid multi-focus multi-photon 3D printing. We discuss more sensitive multi-photon photoresists for lower required laser powers. Furthermore, we outline the status of parallelized two-color 3D light-sheet laser microprinting using inexpensive continuous-wave lasers.
