Color: 314 - 1.75mm Fiberon Pa6-gf25 Grey 3kg (Hex Code: #75787b)


Size: NYLON


Features

  • Strong Nylon for Load-Bearing Parts: PA6-GF25 combines 25% glass fiber reinforcement with Nylon 6 to provide high strength, stiffness, impact durability, and layer adhesion for brackets, housings, jigs, fixtures, automotive components, and mechanical parts.
  • Engineered Heat Performance: After annealing at 100C for 16 hours, test specimens reach an HDT of 191C at 0.45 MPa and 157C at 1.8 MPa. These results are not continuous-use temperature ratings; actual performance depends on load, geometry, moisture, print orientation, and processing conditions.
  • Use an All-Metal Hotend and Hardened Nozzle: Print at 280300C with a 4050C build plate and the cooling fan off. Do not exceed the recommended bed temperature, as excessive heat may increase warping. A heated chamber is not required. Speeds up to 300mm/s are possible after calibration.
  • Important Post-Printing Guidance: Anneal printed parts at 100C for 16 hours when maximum thermal and mechanical performance is required. Remove same-material supports before the part absorbs excessive moisture, as the supports may become difficult to separate. Validate dimensions after annealing.

  • My new favorite filament
Color: 314 - 1.75mm Fiberon Pa6-gf25 Grey 3kg (... Size: NYLON
This review is for the PA6-GF My settings: Neptune 4 plus with enclosure, Microswiss hotend and upgraded fan shroud. Nozzle 290, bed 50 (yes, only 50). And you definitely need a hardened nozzle AND hardened gears. I was blown away by how easy this is to use. I have more consistent success with this filament than even PLA. The parts are incredibly strong, I was able to thin the walls of some of my prop designs from 12mm in PLA Plus to 4mm with this. It also had a slight flex to it which helps with impact resistance (so it won't just shatter). They also look great! Layer lines are hardly noticeable even at 0.2mm layer heights. It comes out with a rough texture that can be sanded. And so far I have had no adhesion issues. Supports usually snap off, although sometimes I need to use a razor blade on the tiny supports where they meet the print. Still, no worse than PLA. That said, there are some things to keep in mind: You have to print from and actively heated filament dryer. I splurged and got the EIBOS Polyphemus dryer, which was $150ish. I wanted it anyway but a good dryer that can consistenly keep the temperature at 70 is a must (70C is what I use for all prints with this filament). I also print with an enclosure. I'm not sure if you need it for the filament itself, but it gives off toxic particles. I have an activated carbon filter running at all times in the enclosure, you should too. Lastly, this is fiberglass. Working with fiberglass is dangerous, ESPCIALLY inhaling any particles. I recommend handling the prints with gloves (they have a rough texture and there's a risk of tiny glass splinters). And ALWAYS use a respirator when sanding these parts. At $120 for 3kg it's not a bad deal. I've stocked up on some rolls in case of coming tariffs, but I'll definitely be using this for a long time. ... show more

  • Constantly jams.

These rolls jam and have spool failures vastly more than any other filament we’ve ever used.
