In summary, we have developed a new electrode fabrication method, termed print-and-plate, that combines the precise and tunable architectural control of direct ink writing with metal-like conductivity achieved by electroplating, which are guided by real-time electrochemical fluorescence imaging and computational design. By tracking the transient dynamics of the output current with stepwise changes in overpotential, we demonstrated excellent agreement between output current and fluorescence intensity along with the onset of mass-transport limitation at overpotentials with magnitude exceeding ~150 mV.
