Why Choose Alumina 4N Resin?
Alumina 4N Resin is a high-density and high-purity technical ceramic 3D printing material with exceptional performance in extreme environments: thermally resistant, hard, abrasion resistant, mechanically strong, and chemically inert.
Ceramic 3D Printing Made Accessible
The most affordable and easiest-to-use ceramic 3D printer in the world. Over 10x lower starting price compared to the leading alternatives.
Extreme Performance
Reliable in extreme applications with a max working temperature of 1500°C, maintaining an impressive flexural strength of over 400 MPa in addition to resisting compression and deflection with a modulus of 380 GPa.
Unprecedented Design Freedom
Fabricate ceramic components with intricate internal channels, latticed structures, and complex geometries that are impossible with traditionally manufactured alumina. Optimize parts without sacrificing quality or performance.
Shortened Turnaround Time and Reduced Costs
Ditch expensive tooling and molds for reduced production costs and a quicker end-to-end process for a faster development cycle overall.
Applications
Alumina 4N Resin is a cost and time-effective solution for fabricating high-performance parts for extreme environments. Parts printed in Alumina 4N Resin serve as good heat and electrical insulators, heavy-duty tools, as well as chemically resistant and wear-resistant components.
They are used in industries such as defense, manufacturing, chemicals, and automotive.

Post-Processing
Wash Process
- Wash the printed parts for 2 minutes in Ceramic Wash Solution
- se a separate wash bucket to prevent loose ceramic particles from adhering to non-Alumina 4N parts
- Do not allow Alumina 4N Resin parts to come into contact with water or IPA, as this will cause cracking
- Only wash Alumina 4N Resin in the Ceramic Wash Solution
Firing Alumina 4N Resin
- Dry parts for 24 hours prior to firing
- Fire parts on setter plates rated for a minimum of 1700 °C
- Formlabs recommends the two furnace schedule below, but several options for firing exist
