Ultimaker CPE+

Ultimaker CPE+ is an engineering copolyester material with high chemical and temperature resistance (100 °C). It also is very tough (will elongate >100% before breaking) and has high impact resistance (37 kJ/m² notched Charpy).

Key features

Excellent chemical resistance, temperature resistance, toughness, and dimensional stability. Allows printing of translucent parts with the transparent filament option.

Food contact and in vivo applications. Long term outdoor usage or applications where the printed part is exposed to temperatures higher than 100 °C.
