In the prior art, the air tight door of the working cabin is required to be opened to replace a new wire winding disc, for the vacuum electron beam fuse equipment, the time for replacing is more than 6 hours, which comprises the procedures of cooling parts, deflating, wire supplementing, vacuumizing again and the like, and for the arc or laser fuse forming process, the time for replacing is about 20 hours, which comprises the procedures of releasing inert gas, supplementing wires, re-air washing, pressurizing and the like. Therefore, the existing metal 3D printing technology is extremely time-consuming for replacing a new wire winding disc for large parts, resulting in low efficiency; in addition, in the process of replacing the wire winding disc, the quality defect of the joint of parts before and after wire replacement is easy to occur due to the need of changing the atmosphere state and/or the temperature and/or the pressure and other environments in the working cabin.
