An apparatus and method for electrochemically depositing a unitary layer structure using a reactor configured to contain an electrolyte solution with an anode array containing a plurality of independently electrically controllable anodes arranged in a two-dimensional array, a cathode, an addressing circuit configured to receive a signal containing anode address data and configured to output a signal causing an anode array pattern; and, a first controller being a current controller configured to control a flow of current to the anode array; a second controller in communication with the addressing circuit, the current controller and the anode array, the second controller operable to communicate with the current controller to command the flow of current to each anode in the anode array causing an electrochemical reaction at the cathode to deposit a layer corresponding to the anode array pattern signal received from the addressing circuit; and a third controller configured to clear bubbles which have formed on the anode after a length of time of steady state deposition by controlling the flow of the electrolyte solution across the anode array surface.
