Dip‐in direct‐laser‐writing (DLW) optical lithography allows fabricating complex three‐dimensional microstructures without the height restrictions of regular DLW. Bow‐tie elements assembled into mechanical metamaterials with positive/zero/negative Poisson's ratio and with sufficient overall size for direct mechanical characterization aim at demonstrating the new possibilities with respect to rationally designed effective materials.
