FIBREX PEI+GF30 MADE USING ULTEM PEI

FibreX™ PEI+GF30 Glass Fiber Reinforced Filament, Made Using ULTEM™ 1010 PEI

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.

Benefits of PEI+GF30 Include:

• High thermal properties, with a Tg of 217°C and HDT of 212°C
• 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, including automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
• Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Filament Specifications:

1.75mm in diameter. 3DXTECH currently offers 250g, 500g and 1kg spools in Natural.

Recommended Print Settings:

• Extruder: 370-390°C
• Bed Temp: 120-160°C
• Nozzle: We highly recommend a hardened steel nozzle with a minimum diameter of 0.4mm for abrasive materials such as this
• Layer Height: 0.25mm or higher
• Bed Prep: Nano Polymer Adhesive gives us the best results
• Heated Chamber: Recommended, an enclosure helps reduce warping and improves print success.
• Supports: ThermaX™ HTS2 High-Temp Support is designed to work with complex, high-temp materials just like this
• Drying Instructions: 120°C for 4 hours

Abrasive Material

This material is particularly abrasive among 3D printing filaments. Standard brass nozzles can be chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter widens inconsistently and the printer will experience extrusion issues. Use hardened steel nozzles with this filament to maximize toolhead life and quality of your prints!
