Additive manufacturing of parts comprising electrophoretic and electrolytic deposits

A method for additive manufacturing of a part comprising an electrolytic deposit and an electrophoretic deposit, the method comprising:

• providing an additive manufacturing system comprising deposition control circuits, an electrode array comprising individually-addressable electrodes each electrically coupled to one of the deposition control circuits, and a deposition electrode;
• providing an electrolyte solution between the electrode array and the deposition electrode, wherein the electrolyte solution comprises cations;
• applying a first voltage between a first set of the individually-addressable electrodes and the deposition electrode thereby driving the cations to the deposition electrode and reducing the cations into the electrolytic deposit of the part on the deposition electrode;
• replacing the electrolyte solution with an electrophoretic suspension between the electrode array and the deposition electrode, wherein the electrophoretic suspension comprises solid charged structures;
• and
• applying a second voltage between a second set of the individually-addressable electrodes and the deposition electrode thereby driving the solid charged structures to the deposition electrode and depositing the solid charged structures as the electrophoretic deposit of the part on the deposition electrode.
