Its unique properties include high-temperature resistance, even up to 180ºC, resistance for natural and synthetic solvents, high dielectric strength and good thermal conductivity. PEI comparing to PEEK and PEKK shows slightly lower strength, stability and creep resistance.
Due to its properties material is widely used in railroad, aerospace and automotive industries. 3D printed ULTEM parts are used as metal parts replacements.
This material is also known as PEI (polyetherimide). Filament can be made from many different polymer grades, most common is AM9085F. 

ULTEM™ 9085 is a trademark of SABIC.

ULTEM™ AM1010F Filament is a high-performance thermoplastic material designed specifically for 3D printing applications. Known for its exceptional thermal and mechanical properties, ULTEM™ AM1010F offer excellent strength and durability.

This filament is ideal for producing parts that require high heat resistance, chemical stability, and dimensional stability. Its high melting point and flame-retardant characteristics (UL94-V0) make it suitable for demanding engineering and industrial applications, providing consistent performance in extreme conditions. Additionally, ULTEM™ AM1010F complies with Aerospace FAR25.853 standards, ensuring its suitability for use in aerospace applications.
