Sintered metal objects from a standard FDM 3D printer

Filamet(TM) metal-infused filament with Bronze, Copper (soon Brass, Nickel-Silver?) for producing high-density metal objects, sintered in a kiln, after being printed on a
cheap, run-of-the-mill FDM printer. Wondering about shrinkage/deformation from heating, but this sounds promising for non-m/billionaires.

Now that is very interesting. Thanks for posting that.

At scales to be at all relevant, say, 12" cube width and above, plain old machining is practical and cheap. Porous, sintered messes based on plastics will be dimensionally unstable and a horror show under vacuum.

How does this compare to lost-PLA metal casting? I'm guessing not nearly as good.

What would happen if we printed with YBCO infused PLA on a spherical table? Maybe we could print a proper, superconducting bowed cube-octahedral Polywell in one go. If we switch between plain PLA for the running surface, copper infused for the case, and YBCO infused for the windings…

Looking at the list of "Customers who trust", it's all universities and government agencies. Perhaps this is telling...

“ In the case of copper, the highest density achievable would be about 97 density with 15 percent shrinkage, but shrinkage can be kept to under 7 percent with 10 to 12 percent porosity.”
So, definitely not vacuum tight. And I don’t see anything about printing superconductors.

Nitrogen (LN2) doesn’t diffuse much.
Has anyone ever even suggested YBCO to them?
