Method for manufacturing high-precision ceramic-based circuit based on electric field driven spray deposition micro-nano 3D printing

The invention discloses a high-precision ceramic-based circuit manufacturing method based on electric field driven spray deposition micro-nano 3D printing, and the method comprises the steps: firstly, coating a layer of sacrificial layer material on a pretreated ceramic substrate, and solidifying a sacrificial layer; then, according to the designed circuit, conductive ink serves as a printing material, electric field driven spray deposition micro-nano 3D printing is adopted, and a conductive structure is printed on the ceramic base material coated with the sacrificial layer; then, a high-temperature sintering process is used, various organic solvents in the sacrificial layer and the conductive ink are removed, and the conductive circuit and the ceramic base material are combined into a whole through the conductive ink; and finally, post-processing the sintered ceramic circuit board, and drying the finished product. According to the method, three strategies of sacrificial layer coating, electric field driven s
