Described herein are electrochemical-additive manufacturing (ECAM) systems comprising electrophoretically-deposited masks selectively covering a set of individually-addressable electrodes (pixels) in the electrode arrays (printheads). For example, an electrophoretically-deposited mask, comprising one or more patches, can be used to block the electric current through certain array portions thereby preventing electrolytic deposition on the corresponding portions of the deposition electrode during ECAM processes. In some examples, electrode array portions can be masked to cover damaged portions (e.g., stuck-on control circuits, electrically and/or ionically conductive passages in the electrode array) and/or to form special patterns of inactive array portions (that no longer need to be controlled using deposition control circuits). Such electrophoretically-deposited masks can be formed in an ECAM system or an external system. The mask forming can be a single-stage process or a multi-stage process. Furthermore, the mask position can be self-defining, e.g., based on defect location and/or severity of defects.
