1. An electrochemical-additive manufacturing method comprising:
providing an electrochemical additive manufacturing system comprising a system controller, a deposition power supply, deposition control circuits, an electrode array, a deposition electrode, and an electrolyte solution, wherein:
the deposition control circuits are communicatively coupled to the system controller and electrically coupled to the deposition power supply,
the electrode array comprises individually-addressable electrodes, each electrically coupled to one of the deposition control circuits, and
the system controller comprises a target map comprising individual target currents, one for each of the individually-addressable electrodes; and
depositing a material onto the deposition electrode from the electrolyte solution by flowing a current between a first subset of the individually-addressable electrodes and the deposition electrode while the individually-addressable electrodes and the deposition electrode are in an initial position relative to each other, wherein the current is independently controlled by each of the deposition control circuits based on a corresponding one of the individual target currents for the first subset in the target map;
moving the electrode array and the deposition electrode relative to each other using at least one of a linear translation or rotation from the initial position to a shifted position;
using the system controller, based on a relative position of the electrode array and the deposition electrode, creating an updated target map using the individual target currents shifted based on a spatial reference between the initial position and the shifted position; and
depositing an additional material onto the deposition electrode from the electrolyte solution by flowing an additional current between a second subset of the individually-addressable electrodes and the deposition electrode using the updated target map while the individually-addressable electrodes and the deposition electrode are in the shifted position.
