eSUN ePA-GF glass fiber reinforced nylon filament
Abstract: Nylonis a generic designation for a family of synthetic polymers, and the first commercially successful synthetic thermoplastic polymer.
Nylon polymers have found significant commercial applications infabricand fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).
To meet the needs of commercial manufacture, nylon is much improved in strength, heat resistance and cold endurance. Years ago eSUN has developed two nylon filaments— ePA and ePA-CF. Compared to normal filaments, ePA is highly fire-resistant; and to keep this feature we upgraded ePA to be ePA-CF, a green carbon fiber reinforced nylonfilament with 20% of carbon fiber.
This time we adopt short glass fiber and create a new nylon filament—ePA-GF—glassfiberreinforcednylon filament
About ePA-GF
1. ePA-GFis a beigetranslucentfilament;
2. As a intermediate loadingglassfiberreinforcednylon, it’s much improved in mechanical strength, rigidity, modulus, etc comparing to pure nylon filament;
3. Improvedcreep resistance, fatigue resistance, heat resistance and the distortion temperature can be 120℃. It has excellent print performance, which print smoothly with no edge warping;
4. Smooth, fine surface and no outside leakageof glass fiber, which avoid the harm of touch;
5. Theglass fiber decreases the shrinking percentage compared to pure nylon, so big prints are less likely to shrinkanddeform.

Printing parameters
- Bestprint temperature: 240-260℃
- Bed temperature: 60-90℃
- Feed rate: 30-90mm/s
- Idling speed: 90-150mm/s
Printing notices
1. Suitable for all kinds of FDM 3D printer. It’s suggested to print with hardened steel nozzle because ePA-GF will wear down brass and aluminumnozzles;
2. Works with different print surface like 3M tape, Kapton tape, glass, etc;
3. Keep anoptimumdistancebetween nozzle and plate. The best distance is 0.2-0.3mm; ePA-GFmay unable to print smoothly with distance less than 0.2mm;
4. A lower filling rate can remit shrinkage crack during printing process;
5.Better keep cooling fan off when printing and print in a closed area. Puttingflapperaround printer helps to keepconstant temperatureenvironment;
6. It’s suggested to polish the print after to remove a few outside leakage of fiber on surface.
PS: The filament is fully dried before vacuum packaging. Youcan reserve in ziplockbagwith desiccantor dry 3-4 hours in 80℃ oven to ensure the best print effect.
Applicationarea
ePA-GFis perfect to produce gear, bearings, air wing, pump, bicycle parts, automobile parts, fishing gearand other heat-resistant structural plasticparts for aerospace, automobile, mechanical engineering, chemical engineering.
