The process worked out by VegOilGuy seems really good.

Foundry

I like the electric design. Since this is downstream of the basic 3D printer, we can print a set of molds to go inside when casting the cement. This will leave a precise spiral for the heating element.

Inductive

Requires a more complex driver but we can melt metal right in the crucible with very little insulation. More efficient because the energy goes right into the metal rather than heating a larger volume.
