An extremely efficient 3D printing filament called GF-PEI uses 30% glass fiber reinforced PEI [Polyether Imide] resin. Excellent thermal performance, great dimensional stability, built-in flame resistance, and very high chemical resistance are all included in this material.

Benefits of GF-PEI Include:

• High thermal properties, with a Tg of 217°C and HDT of 212°C
• Inherently flame-resistant
• Long-term hydrolytic stability makes steaming and autoclaving simple.
• Highly consistent part-to-part dimensions are made possible by excellent dimensional stability, low heat creep sensitivity, and a very low, homogeneous coefficient of thermal expansion.
• Outstanding rigidity and strength even at high temperatures
• Automotive fluids, completely halogenated hydrocarbons, alcohols, and aqueous solutions are just a few of the chemicals that have good resistance to a wide range of substances.
• Dielectric constant and dissipation factor stability over a broad temperature and frequency range

We use actual PEI (polyether imide) resin to create this ultra-performance 30% glass fiber reinforced 3D printing filament. Due to their high glass transition temperature (Tg) of 217°C, ULTEM resin filaments enable the creation of parts with good characteristics at high temperatures.An amorphous, high-performance polymer called PEI combines remarkable chemical resistance, exceptional dimensional stability, excellent thermal characteristics, and inherent flame retardancy.
