Prusa - Prusament PEI 1010 Natural 500g (NFC)

This filament is not suitable for the Prusa MK, XL and MINI series printers as the temperature needed to print this material is not attainable.

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.

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).
