Formlabs Alumina 4N Resin
This product requires a complex, multi-day workflow and extra equipment, including kilns, to achieve a sintered alumina part.
Embrace the future of ceramic engineering with the most affordable ceramic 3D printing ecosystem in the world. Introduce the power of 3D printing to manufacture your advanced ceramic components without expensive tooling, and reduce production costs and lead times while increasing design freedom.
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.
A stainless steel build platform is required when printing with Alumina 4N Resin (use either Form 3 Build Platform 2 or Form 3 Stainless Steel Build Platform).
Alumina 4N Resin has a total shelf life of 3 months at room temperature. Refrigerating your resin (at -10–4 °C) can add up to 12 months of additional shelf life. We recommend refrigerating Alumina 4N Resin.
Why Choose Alumina 4N Resin?
Alumina 4N Resin is a 99.99% pure alumina technical ceramic with 98.6% relative density, and exceptional thermal, mechanical, and conductive properties — comparable to traditionally manufactured alumina (Al2O3).
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.
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.
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.
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.
Consider Alumina 4N Resin for:
High voltage components: enclosures, connector housings and covers, terminal blocks
Thermal protection: spark plug insulators, electrical mounting, insulating housings or tubes
Chemical resistance: manifold pipes, mixing blades and pipes
Foundry tools for metal casting: cores, crucibles, gating, sprues, mixing tools, thermocouple sheaths, metal filters
