We manufacture this ultra-performance 30% glass fiber reinforced 3D printing filament using real ULTEM PEI (polyether imide) resin from Sabic. Filaments made from ULTEM resin offer the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 217°C.
PEI is an amorphous, high-performance polymer which combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance.


High thermal properties, with a Tg of 217C and HDT of 212C
Inherently flame-resistant
Long-term hydrolytic stability, making it easy to steam and autoclave
Excellent dimensional stability, low heat creep sensitivity, and a very low, uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions
Exceptional strength and stiffness, even at elevated temperatures
Good resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Packed with your favorite products, detailed information, and essential technical data. Whether your brand new to 3-D printing or need to find a specific filament that best fits your project, our catalog has everything you need in one easy-to-navigate place!

Explore key attributes like tensile strength, flexural strength, glass transition, and fire testing performance. Whether you're prototyping, creating functional parts, or printing detailed models, these property graphs will help you find the perfect filament for your project.
