PEI (Polyetherimide) filaments are advanced 3D printing materials designed for the most demanding users. They are characterized by exceptional mechanical strength as well as thermal and chemical resistance. Thanks to these properties, they are widely used in industries where reliability and safety are critical - such as aerospace, automotive, railway, and medical sectors.

PEI filament, produced from ULTEM™ 9085 resin, stands out for its flame retardancy (UL94 V0), low smoke and toxic fume emissions, and compliance with strict industrial standards (including FAR 25.853 and EN45545). Prints made from PEI maintain dimensional stability even at temperatures reaching 180-190°C, making this material ideal for parts that operate under extreme conditions.

With its high strength-to-weight ratio, PEI filament serves as an excellent alternative to metal, allowing for the production of lighter yet highly durable components.

Printing with PEI requires 3D printers designed for high-temperature materials, equipped with a heated chamber and a high-temperature-resistant extruder. It is a material of choice for professionals who demand unmatched quality, durability, and precision.
