Original Abstract Submitted
described herein are printheads for electrochemical-additive manufacturing (ecam) comprising extended electrode interconnects and other features for preventing electrolyte ingress and protecting the electrode-interface circuits of these printheads. for example, an electrode interconnect may comprise a metal trace extending in-plane between and interconnecting two vertical (out-of-plane) conductors such that the shortest/direct distance between these vertical conductors is substantially smaller than the length/path of this metal trace. as such, the metal trace substantially increases the electrolyte migration path between these vertical conductors. furthermore, multiple metal traces (at different levels) may be used with vertical conductors being offset from each other. finally, electrode edges may protrude into the insulator recesses thereby preventing these edges from peeling and increasing the contact interface between the electrodes and the insulator. electrode edges may be covered with a protective layer to ensure uniform current density through the exposed electrode surface.
