Throughout the process, the 3D printed component is submersed in a fluid electrolyte solution. The component operates as the adversely billed cathode, while a steel bar operates as the positively charged anode. An electric current is related to the option, creating steel ions to migrate from the metal bar to the surface of the 3D printed component, developing a new metal layer. In cool welding, the surface areas to be signed up with are very first prepared by eliminating any type of surface area impurities, such as oxides
