Abstract
Three-dimensional (3D) printing technology can be used to easily and rapidly produce complex shapes. In this study, an electrode tool used for electrochemical machining (ECM) was fabricated using a 3D fused deposition modeling (FDM) printer. The electrode tool was made from acrylonitrile butadiene styrene (ABS), a low-cost material commonly used in 3D printing. Since the electrode printed with ABS material is non-conductive, additional conductive coating was applied to the tool surface. Electrical conductivity characteristics and coating thicknesses were analyzed with respect to the number of coatings to identify optimal coating conditions. The ECM performance of the fabricated electrode was then compared with that of a conventional copper electrode tool. The effect on the shape of the 3D printing electrode during machining according to the type of coating was analyzed. The thermal effect of the current applying had to be considered, and a suitable coating type was selected based on the experimental results. The fabricated ECM electrode can achieve significant machining quality to the existing electrode performance, and through the results of this study, it was possible to increase sustainability in the manufacturing industry with advanced machining technology.
