The influence of the working cell geometric parameters on electrochemical 3D printing accuracy

The main technological parameters of electrochemical 3D printing are the rate of metal deposition and resolution. Electrochemical 3D printing resolution can be characterized by the ratio between the estimated metal deposition area width and the working electrode-anode diameter. In this work, the influences of the diameter of the working electrode-anode and the inter-electrode distance on electrochemical 3D printing accuracy have been investigated. The purpose of the study was to establish the influence of electrochemical cell geometric parameters' ratio on electrochemical 3D printing resolution. The author used the sources of Ukrainian scientists such as R. Babchuk, V. Vorobyova, O. Linyucheva, M. Kotyk, G. Vasyliev and foreign researchers such as K. Bouzek, K. Borve, O. Lorentsen, K. Osmundsen, I. Rousar, J. Thonstad, M. Rafiee, R. Farahani, D. Therriault and others. It was shown that the smaller the diameter of the anode (dielectric capillary) and the greater the distance from the anode dielectric housing edge to the surface of the cathode (interelectrode distance), the wider the metal deposition area. It was found that the larger the working electrode diameter, the larger the inter-electrode distance can be used to ensure the required electrochemical 3D printing resolution.
