About ePA-GF

1. ePA-GF is a beige translucent filament;

2. As a intermediate loading glass fiber reinforced nylon, it's much improved in mechanical strength, rigidity, modulus, etc comparing to pure nylon filament;

3. Improved creep 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 leakage of glass fiber, which avoid the harm of touch;

5. The glass fiber decreases the shrinking percentage compared to pure nylon, so big prints are less likely to shrink and deform.

Printing parameters

  1. Best print temperature: 240-260℃
  2. Bed temperature: 60-90℃
  3. Feed rate: 30-90mm/s
  4. 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 aluminum nozzles;

2. Works with different print surface like 3M tape, Kapton tape, glass, etc;

3. Keep an optimum distance between nozzle and plate. The best distance is 0.2-0.3mm; ePA-GF may 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. Putting flapper around printer helps to keep constant temperature environment;

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. You can reserve in ziplock bag with desiccant or dry 3-4 hours in 80℃ oven to ensure the best print effect.
