Method for three-dimensional printing of magnetic materials

A three-dimensional magnetic printer comprising:

• an induction head assembly including a vessel, an induction heater to heat magnetic material to form an alloy melt in the vessel and at least one nozzle with a nozzle control device operable to eject the alloy melt from the vessel;
• a coating apparatus comprising a sprayer;
• a base aligned with the at least one nozzle;
• and
• a 3D printer controller configured to at least one of adjust an opening defined by the nozzle control device, regulate flow of a pressurized gas into the vessel, control movement of the induction head assembly, and adjust current to induction heater,
• wherein the induction head assembly deposits at least one alloy melt layer and the coating apparatus forms at least one insulating layer onto the base in accordance with a predetermined pattern to form a three-dimensional article.

A three-dimensional magnetic printer comprising:

• a plurality of induction head assemblies, wherein each of the plurality of induction head assemblies comprises a vessel and an induction heater to heat magnetic material to form an alloy melt in the vessel and at least one nozzle with a nozzle control device operable to eject the alloy melt from the vessel;
• a coating apparatus comprising a sprayer;
• and
• a base aligned with the at least one of the nozzles,
• wherein the plurality of induction head assemblies deposit a plurality of alloy melt layers and the coating apparatus forms at least one insulating layer onto the base in accordance with a predetermined pattern to form a three-dimensional article,
• wherein the plurality of induction head assemblies deposit different alloy material layers onto the base.
