Abstract

We present a device and method for additive manufacturing of multi-metal microstructures. Our device integrates hydrodynamic flow confinement of an electrolyte with micro anode based localized electrochemical deposition. The flow confinement enables on demand switching of the electrolyte composition surrounding the micro anode, facilitating real-time control of the deposited metal. Furthermore, the hydrodynamic flow confinements ensure a constant stream of electrolyte to the reaction site, eliminating the effects of ion depletion. We here detail the principles of our approach and present a working prototype along with preliminary results of printed multi-metal microstructures.
