Package contains: 1 x FIBREX PEI+GF30 MADE USING ULTEM PEI - Natural / 1.75mm - 3DXTech
We manufacture this high performance 30% glass fiber reinforced 3D printing filament using Sabic's genuine ULTEM PEI (polyether imide) resin. Filaments made from ULTEM resin offer the ability to create parts with excellent properties at high temperatures due to a high glass transition temperature (Tg) of 217°C.
PEI is a high performance amorphous polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy and good chemical resistance.
The advantages of PEI+GF30 include:
High thermal properties, with Tg of 217°C and HDT of 212°C
Inherently flame resistant
Long-term hydrolytic stability, facilitating steaming and autoclaving
Excellent dimensional stability, low sensitivity to thermal creep, and a very low and uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions
Exceptional strength and stiffness, even at elevated temperatures
Good resistance to a wide 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:
1.75 mm and 2.85 mm +/- 0.05 mm diameter
Recommended print settings:
Extruder: 370-390°C
Bed temperature: 120-160°C
Nozzle: we strongly recommend a hardened steel nozzle with a minimum diameter of 0.4 mm for abrasive materials such as this
Other: the ideal layer height is 60% of the nozzle diameter. We do not recommend printing layers smaller than 0.2 mm with abrasive filaments
Bed Prep: Nano Polymer Adhesive gives us the best results
Heated Chamber: recommended, a wrap helps reduce warpage and improves printing success.
Media: The ThermaX High Temperature Media? HTS is designed to work with complex, high-temperature materials just like this
Drying instructions: 120°C for 4 hours

Abrasive material
This material is particularly abrasive among 3D printing filaments. Users may find that standard brass nozzles are chewed up very quickly compared to standard wear. If worn, the nozzle diameter will expand inconsistently and the printer will encounter extrusion problems.
For this reason, we strongly recommend printing this material through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easy to install depending on the printer manufacturer's instructions.
