Additional information

Recommended temperature for heated bed is ≥120°C. Adhesion is possible on different surfaces. PEI ULTEM™ 9085 can be used on desktop FDM or FFF technology 3D printers able to reach the high required temperatures. Dry the spool before printing: +4 hours at max. 110°C.


Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
