Abstract
An electromagnetic induction fast metal melting nozzle for 3D metal printers, which consists of nozzle (R), crucible (C), heat insulation layer (A), medium and high frequency inverter power supply (P), electromagnetic induction coil (B), The cooling device (D), the metal to be melted (M) and the feeding device (S) are composed. The electromagnetic induction coil (B) surrounds the crucible (C) through the heat insulating layer (A), and the cooling device (D) provides cooling for the electromagnetic induction coil (B) and the medium and high frequency inverter power supply (P), and the medium and high frequency inverter power supply (P) Drive the electromagnetic induction coil (B), so that the metal to be melted (M) in the crucible (C) is rapidly melted by electromagnetic induction to form a metal fluid or liquid (L), and the metal fluid or liquid (L) is sprayed through the nozzle (R) out. It can realize cost-effective 3D metal printing, has high energy conversion efficiency, can provide higher deposition rate, smaller oxide layer, higher safety, can print quickly, and can manufacture large-scale metal components.
