Create real metal parts using any open-architecture FFF/FDM 3D printer—or even a 3D printing pen.
Available Formats:
Spools: 1.75mm and 2.85mm diameters in 0.25kg and 0.5kg weights
Pellets: 1kg jars
Filament Density:
1.20g/cc – 1.50g/cc
Metal Content:
60.0% – 69.0% 6061 aluminum
High Compatibility:
Works with virtually any open-architecture 3D printer—no proprietary hardware or specialized equipment required. Also compatible with 3D printing pens.
Is Aluminum 6061 Right for Your Project?
Aluminum 6061 is a specialized material designed for lightweight aerospace and automotive prototyping. Due to its high reactivity, it requires an Expert-Level sintering environment (typically a vacuum furnace or high-purity inert gas).
If you are looking for a "Plug-and-Play" metal printing experience using a standard kiln, we recommend our High-Success Materials:

Why Consider Copper or Bronze?
While Aluminum is attractive for its weight, our Copper and Bronze filaments offer a much higher success rate for users using standard equipment:
Bronze Filamet™: Our most popular entry-level metal. It is extremely forgiving in the kiln and polishes to a beautiful, mirror-like gold finish.
Copper Filamet™: Ideal for functional parts requiring thermal or electrical conductivity. It is significantly easier to sinter than Aluminum.

Easy Printing Experience:
Print with a 0.6mm hardened steel, standard flow nozzle
Prints similar to PLA
Minimal to no warping
Ensure the filament feeds straight into the extruder
Less hygroscopic than PLA
Do not dry this filament—drying will degrade the binder

Fully Sinterable:
After printing, your part can be fired in a furnace to become 100% metal.
👉 We are unable to offer any debinding and sintering support for this filament.
👉 Sintering development is being conducted by one of our users. Current information and updates can be found here, as well as in our Discord server here.
