System and method for magnetohydrodynamic (MHD) printhead/nozzle

A method for operating a printer, comprising:

• adding a first print material having a first melting point to a supply reservoir at a first rate;
• adding a second print material having a second melting point to a supply reservoir at a second rate;
• and
• allowing the first print material and the second print material to combine to form a diluted print material;
• and
• wherein the first print material and the second print materials comprise a metal or metal alloy.

A printing system, comprising:

• an ejector for jetting a print material, comprising:
• a supply reservoir;
• a first print material feed system configured to provide a first print material into the supply reservoir at a first controlled rate;
• a second print material feed system configured to provide a second print material into the supply reservoir at a second controlled rate;
• and
• a nozzle in connection with the supply reservoir and configured to eject one or more drops of liquid print material;
• wherein:
• the first print material and the second print material combine to form a diluted print material;
• and
• the first print material and the second print materials comprise a metal or metal alloy.
