Aluminum 6061 Filamet™ prints lightweight aluminum parts on an open-architecture FFF/FDM printer, for lightweighting and geometries that normally need CNC machining or casting. It is the most demanding metal in the range to sinter, so read the sintering note before you buy.

Specifications

Metal content: 60.0%–69.0% 6061 aluminum
Filament density: 1.20–1.50 g/cc
Formats: 1.75mm and 2.85mm spools, and pellets (pick in the variant selector)
Nozzle: 0.6mm hardened steel, standard flow

Printing

Prints similar to PLA with minimal to no warping
Feed the filament straight into the extruder
Do not dry it: drying degrades the binder

Sintering: expert level

Aluminum is highly reactive, so sintering needs an expert-level environment, typically a vacuum furnace or high-purity inert gas. It is not a plug-and-play kiln material. Sintering development is being done by the user community, and The Virtual Foundry does not offer debinding or sintering support for this filament.

If you want a standard-kiln workflow, start with Copper or Bronze Filamet™ instead.

Applications

Aerospace component prototyping and lightweighting
Drone frames, brackets and structural parts
Lightweight automotive components
University and R&D research

About this product

Will it print on my printer?

Filamet works on nearly all open-architecture FFF/FDM printers. Swap in a hardened steel nozzle (the size is in the specifications above) and print it like PLA. Not sure about your model? Email us the printer name and we'll check before you buy.

Why is aluminum sintering rated expert level?

Aluminum is highly reactive and melts low relative to its sintering temperature, so it needs a tightly controlled vacuum or high-purity inert atmosphere. A standard air kiln will not work. Community sintering research is ongoing.

Does The Virtual Foundry support sintering this filament?

No. They do not offer debinding or sintering support for this filament, so treat sintering as experimental and expect to work out the process yourself.

Should I dry it before printing?

No. Filamet is less hygroscopic than PLA, and drying degrades its binder, so keep it out of filament dryers. Feed it straight into the extruder.
