Required Resources for 3D Printing with Alumina 4N


This product requires a complex, multi-day workflow and extra equipment, including kilns, to achieve a sintered alumina part. If it is your first time using a Formlabs 3D printer, the manufacturer strongly recommends using a general-purpose resin such as Clear before 3D printing with Alumina 4N.

Alumina 4N resin has unique printing and post-processing requirements compared to other Formlabs resins. At room temperature, Alumina 4N Resin has a shelf life of three months. Refrigeration at -10–4°C can add up to twelve months of additional shelf life. Formlabs recommends refrigerating Alumina 4N Resin.
