FAQs
What makes alumina ideal for high-temperature applications?
Alumina maintains excellent mechanical properties at extreme temperatures (up to 1550°C), offers outstanding thermal stability, and is chemically inert—making it perfect for furnace components, thermal processing, and high-temperature tooling.
How does alumina compare to zirconia for high-temperature use?
Alumina offers superior temperature resistance (1550°C vs 1475°C for zirconia) and better electrical insulation, while zirconia provides higher mechanical strength. Choose alumina for extreme temperatures and electrical applications.
What applications is alumina best suited for?
High-temperature furnace components, electrical insulators, thermocouple protection tubes, laboratory equipment, wear-resistant liners, chemical processing parts, and any application requiring thermal stability with electrical insulation.
Can alumina parts be used in electrical applications?
Yes! Alumina is an excellent electrical insulator with a dielectric constant of 9 and low loss tangent, making it ideal for high-voltage insulation, circuit components, and electrical feedthroughs.
How chemically resistant is sintered alumina?
Alumina is highly chemically inert, resisting most acids, alkalis, and corrosive environments. This makes it suitable for chemical processing equipment, laboratory ware, and corrosive fluid handling.
What design limitations should I consider?
Maximum printed size determined by furnace dimensions, minimum wall: 1mm, minimum feature: 0.6mm. Account for anisotropic shrinkage (different in X/Y vs Z directions).
How long does the complete process take?
Printing varies by model. Chemical debinding takes 6h + 2h drying, thermal debinding ≈60h (or 23h accelerated), and sintering ≈30h including ramp times and holding.
What safety precautions are necessary?
Use in well-ventilated areas, wear FFP2 masks during printing and handling. The sintered alumina is biologically inert and safe for handling.
What’s the shelf life of the filament?
Six months when stored in original vacuum-sealed packaging in cool, dry conditions.
Can I create complex geometries with internal channels?
Yes! This is a key advantage over traditional ceramic manufacturing. Create intricate internal cooling channels, complex fluid paths, and geometries impossible with conventional methods.
See Zetamix in action
Watch how Zetamix ceramic and metal filaments go from spool to dense, sintered part — the same FFF print → debind → sinter workflow we run in-house.
Choose your Zetamix material
Every Zetamix filament prints on a standard FFF 3D printer — we print and validate them in-house on our 3DCeram M.A.T. system — then debind and sinter to a dense ceramic or metal part. The highlighted row is the material on this page; compare the range below:

From process engineers running Zetamix Alumina Filament 1,75mm
Unedited feedback from customers who reorder Zetamix Alumina Filament 1,75mm.
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.
COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
