Engineered Porous Metal Structures via Electroplating in Two-Photon Polymerized Molds

Proceedings
We report the realization of metallic 3D microstructures, electroplated in two-photon polymerized molds. These molds are typically 150 × 150 × 30 µm3 in size and the smallest feature size is about 1 µm.
