Methods of three-dimensional electrophoretic deposition for ceramic and cermet applications and systems thereof

A method for forming a ceramic, metal, or cermet, the method comprising:

• providing an electrophoretic deposition (EPD) device comprising:
• an EPD chamber;
• a first electrode positioned at an end of the EPD chamber;
• and
• a second electrode positioned at an opposite end of the EPD chamber;
• providing a first solution to the EPD chamber using an automated injection system, the first solution comprising a first solvent and a first material;
• applying a voltage difference across the first electrode and the second electrode;
• electrophoretically depositing the first material above the first electrode to form a first layer, wherein the first layer has a first composition, a first microstructure, and a first density;
• introducing a second solution to the EPD chamber using the automated injection system, the second solution comprising a second solvent and a second material;
• applying a voltage difference across the first electrode and the second electrode;
• and
• electrophoretically depositing the second material above the first electrode to form a second layer, wherein the second layer has a second composition, a second microstructure, and a second density,
• wherein at least one of the following provisos are satisfied:
• the first and second composition are different;
• the first and second microstructures are different;
• and
• the first and second density are different.
