This disclosure pertains to a system, methods, and apparatus configured for generating singulated metal droplets and collecting powder metal. The system comprises crucible apparatus each including a crucible housing, a gas inlet, and an alloy nozzle. The crucible housing is operatively coupled to an induction heating element and power supply to provide induction heating of the crucible housing and electromagnetically levitate a mass of molten metal. The gas inlet is operatively coupled to a gas supply and configured to receive a pressurized gas pulse via the gas supply, the pressurized gas pulse being directed at the mass of molten metal. The alloy nozzle is configured to release a metal droplet singulated from the mass of molten level due to the pressurized gas pulse. The system includes a powder collection unit configured to collect powder from one or more dispensing channel configured to catch the falling singulated liquid metal droplet.
