ISO Aluminum Filament for Ultimaker S5


Recommended Posts

They have also the 17-4 stainless steel filament. As far as I know these filaments adopt techniques and processes that are commonly used in metal injection moulding and aluminium can’t be (easily) injection moulded due to oxidation and temperature issues. So I guess there are no aluminium-filaments out there.

I’m no expert in that area, I was just curious about the same thing some time ago because I thought it could probably be easier to process because of its significantly lower melting point, but there seem to be other problems that can’t be easily solved.

There are people on the forum here who use PLA or dedicated mould-making materials to print a model, and then encapsulate that in sand (or whatever special mould-material), then burn the plastic model out, and cast metal into the cavity. I have seen videos of it, but I don't know the exact methods and materials. There are jewelmakers who do this with silver and gold, and also general hobbyists who do it with aluminum. Maybe you can find tutorials on Youtube?
