Fiberlogy PEI 9085 (made from ULTEM™ 9085 resin) is a high-temperature engineering filament used in the aerospace, rail, and automotive industries. It combines exceptional strength, abrasion resistance, and chemical resistance with certified flame retardancy (UL94 V0) and non-toxicity (FAR 25.853, EN45545). This makes it an ideal replacement for metal components in the most demanding applications.
Fiberlogy PEI 9085 is an industrial-grade 3D printing filament made from ULTEM™ 9085 resin. This material has been used for years in the most demanding industries, such as aerospace, automotive, rail transport, and space exploration. Its unique properties make it one of the most prestigious and advanced polymers for 3D printing available on the market.
PEI 9085 stands out for combining the strength of steel with the lightness of aluminum, allowing for the creation of functional replacements for metal components. It holds key safety certifications:
- UL94 V0 – flame retardancy,
- FAR 25.853 – approved for use in aviation,
- EN45545 – compliance with railway industry requirements.
As a result, Fiberlogy PEI 9085 is an approved material for the production of parts used in extreme conditions and in critical sectors of the economy.
The filament is characterized by:
- high-temperature resistance—up to 180°C,
- excellent resistance to abrasion, UV radiation, and solvents,
- high dielectric strength and good thermal conductivity,
- high dimensional stability and resistance to long-term loads.
PEI 9085 is used in projects where typical engineering filaments are insufficient. It is used for:
- structural components in the aerospace and automotive industries,
- components in rail transportation,
- functional replacements for metal parts,
- components exposed to extreme environmental and chemical conditions.
To fully utilize the potential of Fiberlogy PEI 9085, it is necessary to use 3D printers designed for high-temperature materials (PEEK, PEKK, PEI). A heated, enclosed chamber is also essential to ensure even heat distribution and minimize the risk of warping.
