Paper Abstract

In this research, we propose a new monitoring method of the temperature of the molten pool for stable layered fabrication in the metal wire supply type laser 3D printer. The metal wire to be supplied is melted by the laser during molding and flows into the molten pool of the base metal, so that an electric closed circuit is formed. At that time, since the temperature of the molten pool exceeds 1400 ° C., when the metal wire and the base metal components are different, the Seebeck effect produces an output voltage between the base metal and the molten pool and metal wire. From this output voltage, the temperature of the molten ground can be obtained. Furthermore, by applying this method, it is also possible to monitor the component ratio of the gradient material from the voltage generated between each metal wire and the base material when a plurality of different wires are supplied and a gradient material is produced .
