How do they plan to extrude metal? Especially iron or ferrous metals? Even aluminum would take an impressive heating element and then would result in a puddle of metal rather than a controlled plastic flow of material.

Or is the plan just to deposit controlled amounts of material in a small area and build up layer thickness based on the thickness of metal flake? Essentially making a thin layer metal laminate? I'm curious as to their solution for this, and am interested in how you are testing results.
