Formlabs | Alumina 4N Resin

Step into the future of ceramic engineering with the world’s most accessible ceramic 3D printing ecosystem. Harness 3D printing to produce advanced ceramic components without costly tooling—cutting lead times and expenses while unlocking greater design freedom.

Alumina 4N is a Form X material built for expert users, offering a high-density, high-purity technical ceramic. It delivers exceptional performance in extreme environments—thermally resistant, mechanically strong, chemically inert, hard, and abrasion-resistant.

Alumina 4N Resin has a shelf life of 3 months at room temperature, which can be extended by up to 12 additional months when refrigerated (-10–4 °C). Refrigeration is strongly recommended.

Please read the Alumina 4N Quick Start Guide before proceeding. If this is your first time using a Formlabs 3D printer, we strongly recommend using a general purpose resin, such as Clear Resin, before printing with Alumina 4N resin.
