Aluminum Oxide Filamet™

Create real aluminum oxide ceramic parts using any open-architecture FFF/FDM 3D printer—achieving complex insulating geometries, wear-resistant components, and high-temperature structures that are difficult to produce through conventional ceramic forming.

Available Formats:
Spools: 1.75mm and 2.85mm diameters in 0.25kg and 0.5kg weights
Pellets: 1kg jars

Filament Density:
1.50g/cc – 1.65g/cc

Ceramic Content:
59.0% – 63.0% Aluminum Oxide

High Compatibility:
Works with virtually any open-architecture 3D printer—no proprietary hardware or specialized equipment required. Also compatible with 3D printing pens.

Easy Printing Experience:

• Print with a 0.6mm hardened steel, standard flow nozzle

• A Filawarmer is required to print this filament

• 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% ceramic.

👉 We are unable to offer any debinding and sintering support for this filament.

Applications:

• Electrical insulators and substrate components

• Wear-resistant ceramic parts and bushings

• High-temperature kiln components and setters

• Electronic packaging and thermal management

• Functional ceramic prototyping

• University and R&D research programs

• One-off and short-run manufacturing

• Reducing or eliminating tooling and machining costs

FAQ:

❓ Can I print this on my printer?
✅ Filamet™ is compatible with nearly all FFF/FDM based 3D printers on the market. Note: a Filawarmer is required for Aluminum Oxide. Switch out the nozzle for a 0.6mm hardened steel nozzle and get printing! The list of printers that have been used and the ones that are not compatible can be found here: https://thevirtualfoundry.com/trusted-printers/

❓ How strong are parts right off the printer?
✅ They are quite a bit stronger than you may expect. You can throw them around a little and handle them just fine. Generally, they will not handle load nearly as well as the base PLA would on its own.
