Description
PEI 1010 (polyetherimide, branded as Ultem) is one of the most resistant 3D printing polymers, suitable for specialized and demanding industrial applications. The material has a great high-temperature and chemical resistance, and excellent mechanical properties. It is inherently flame-retardant and resistant to gamma radiation. As one of the most resistant materials, it can be used for industrial applications directly as functional parts - it can even be used as a replacement for aluminum alloys. The unique combination of material properties makes it usable for various medicinal or aerospace applications.
Due to very high printing temperatures, this material can be printed only with the Prusa Pro HT90 or a similar printer with a heated chamber (minimum 90 °C). Also, this material is extremely prone to moisture absorption and it is necessary to dry it before every print and keep it in a dry box during the printing.
