Provided is an electromagnetic induction type rapid metal melting spray head for a 3D metal printer. The spray head is composed of a spray nozzle (R), a crucible (C), a heat insulating layer (A), a medium-high frequency inverter power supply (P), an electromagnetic coil (B), a cooling device (D), a to-be-melted metal (M) and a feeding device (S). The electromagnetic coil (B) passes through the heat insulating layer (A) and surrounds the crucible (C), the cooling device (D) supplies cooling to the electromagnetic coil (B) and the medium-high frequency inverter power supply (P), the medium-high frequency inverter power supply (P) drives the electromagnetic coil (B), the to-be-melted metal (M) in the crucible (C) is rapidly melted due to electromagnetic induction so as to form metal fluid or liquid (L), and the metal fluid or liquid (L) is sprayed out through the spray nozzle (R). High-cost-performance 3D metal printing can be achieved, the energy conversion efficiency is high, the high deposition rate, a small
