Size: NYLON
Features
- Stiff, Strong & Heat Resistant Nylon Filament: Polymaker PolyMide PA6-GF nylon filament is a glass fiber reinforced Nylon 6 that offers excellent thermal and mechanical properties without compromising layer adhesion.
- Wide Application: PolyMide PA6-GF is strong, durable, and has excellent heat resistance. It is ideal for applications requiring torsional, tensile, and impact strength, including bicycle pedals, brackets, jigs, drone frames, prosthetics, and handles.
- Tangle-Free & Resealable Bag - Our glass fiber filled nylon filament is carefully wound to prevent tangling, dried, and vacuum sealed in a resealable ziplock bag with desiccant. Always hold the filament tip to avoid nodes, and use the holes on the spool to help prevent this issue.
- Printing Settings - Nozzle: 280-300C; Bed Temperature: 25-50C (Do NOT exceed 50C); Speed: 30-60 mm/s; Annealing: 80C for 6 hours (Recommended for improved heat resistance of printed parts). Bed Surface: Compatible with almost any surface using a thin coat of PVA glue or Magigoo PA.
- Note: An abrasion-resistant nozzle is essential due to the 25% glass fiber in this nylon filament. PolyMide PA6-GF is very stiff, so a proper setup is necessary to ensure smooth feeding and avoid excessive bending in the filament guide system. It's crucial to keep the filament enclosed in a desiccant box while printing and to clean the nozzles after every 8 prints or so.

Size: NYLON
I printed the above image with a stock Kobra Max (260° max nozzle temperature. Although some people suggest it runs hot), 0.8mm nozzle(not a nozzle suggested for small gears)... I have been printing for a well over 5 years and it's not just a side hobby. It's not work but it's an obsession. I've had many printers, I've tried innumerable brands and types of filaments. This is my first favorite. I'm going to write a simple list of why you should buy this filament. By far the strongest filament I have ever used. It's a different kind of strength though. PC FG/cf, peek etc might be stronger in certain ways, But having the same volume as a regular kilogram, yet half the weight, it's just something special. Just a note, the way this filament works is a lot like say porcelain. It's an incredibly strong substance, but if you kind of chip away at it with say a pair of bolt cutters, it'll break easier with scary pieces flying at you.. Kinda like that. Dimensional accuracy is off the charts. You make a hole, the whole will be the size you make it. I only have one printer that prints perfect every time. A toybox printer.. If you know what that is, you'll understand. Anyway, this filament in my Kobra Max, is officially my new most consistent and reliable print. I use Cura to do the "print one at a time" (instead of all at once), and I can have 19 different prints I want done all in that one platform, and it'll just go through one after the other and print them all completely accurate. No more checking every 30 minutes or hour. No need for a camera mounted on it or special failed print sensor... Keep the support material as low density as you can, but when it comes to the support interface and removing this support, it's amazing. The support interface ACTUALLY works...... Really. And once you break off the support which CAN require a lot of strength (ice pick or smaller nozzle size suggested) You're left with a manufacturer quality part. No post-processing necessary. A real quick note, I tried doing the flow reduction for the support material and it ended up failing. I'm sure it's because this material is very thick/.8 nozzle/and printed well below the suggested print temp, But that did fail me. Anyway, I'm sure if you actually have the appropriate setup/settings you'll be fine. Print your support flow to give you ~0.2 mm support line width. Then it should break off super easy, clean and without any excessive strength. Guess that's really all I have to say. Aside from the fact that it also has a really nice texture. Oh, and make sure you use "alternate wall printing direction" or something like that. I'm sure even if you use a smaller nozzle size, there will be a little pull like with metal field or glass filled filaments. You want to make sure it changes direction each layer to avoid that warp and shit. If you use Cura, the newest update has that option in experimental or somewhere at the bottom. This is my summary. I'm using a stock printer, oversized nozzle, and very little is done to try and accommodate this filament suggested print settings. I'm honestly not even sure how it works. But regardless, I'm getting manufacture quality parts. Truly functional. I have every other filament. And although some might have higher strength in certain areas(and usually some disadvantages), but they all require some specialty equipment, tons of work to get it to stick or print clean. High build plate temperatures that waste electricity and often result in warping. And so on and on. And maybe ridiculous for me to say, but I think this is the best filament ever produced...(Aside from basic PLA for prototyping). I just want to know if it comes in 5 kg.

Printed a benchy within a few hours of receiving my spool. I printed directly from my dryer, but didn't wait for it to dry out after loading - call it a factory packaging check. The little boat came out nearly perfect. The only thing I've noticed is that the open-air extrusion is kind of wavy, like the fibers aren't happy about going through my 0.4mm nozzle. I bet a 0.6mm would alleviate this completely. As it stands with the 0.4mm, there is some light waving that makes it into the print but not much. I saw no stringing at all, and the overhangs look fantastic. Surface finish has a unique sheen to it and is *extremely* rough due to the carbon fibers sticking out of it, if I was printing something that will be handled a lot I'd want to put a few coats of clear paint over it first. Flicking the benchy with my fingernail it sounds kind of glassy, suggesting that the part is as stiff as it feels. I like to break the chimney off of benchys to check layer adhesion and this stuff hurt my thumb and took a couple of tries. I bet with annealing and conditioning it would have hurt my thumb even more. Great filament, will reorder when I need it again.

Very nice filament. Comes decently dry out of the box and prints very well. I use the bambu preset for it and I haven't had to do any tinkering with the settings, the surface is beautiful and the print is very solid. Its a little expensive but its tempting to switch over to this for everything. Using glue on the bed i have never had problems with adhesion like I have with abs or asa

Fiberon PA6-CF prints cleanly on a Bambu Lab P1S using Polymaker's own default profile. No custom tuning, no drama, good layer adhesion out of the gate. I dried it minimally and it performed well. After annealing at 210°F for several hours alongside a PA6-GF print, there was no warping or noticeable dimensional change. That's the carbon fiber doing its job, keeping the part dimensionally stable through heat treatment. The surface finish is a flat matte black. It looks intentional and industrial, which works for functional parts. In the hand, it's rough. The carbon fiber gives it an almost sandpaper-like texture that you'll feel immediately. That texture is where the limitations start. Carbon fiber is abrasive. Any part that interfaces with metal, where surfaces slide or wear against each other, is going to chew up the metal side over time. That rules this material out for a meaningful category of functional prints. Polymaker's own PA6-GF avoids this problem entirely. Glass fiber is softer, causes far less wear on mating surfaces, and prints just as reliably on the same default profiles. PA6-CF is stiffer than GF, which matters for parts that need rigidity without flexibility. Brackets, housings, rigid mounts. If your part sits still and holds shape, CF is the better pick. If it touches metal or takes impact, GF wins. It does what it's supposed to. It just occupies a narrow lane, and for most functional printing, the PA6-GF sitting next to it on the shelf is the more versatile choice. I have no doubt this filament will handle the heat. Price seems slightly inflated for what you get. For a specialty filament with a specific use case, that adds up quickly.

This filament prints really well. No bed adhesion issues (inside enclosure) when only heated to 50c on glacier plate or Bambu engineering plate. There's not a lot of information on their website for recommended settings. They do have profiles available for download for many printers. My printer wasn't one of them so, I opened a profile in notepad and transferred the settings to my slicer. It'll print at high speed (300+) but the quality suffers greatly. Printing slow delivers great results. Strong parts with nice finish. It won't feed through my AMS or AMS HT. The gears just grind the filament. It's very stiff. I found success using the AMS HT bypass port and the TPU feed assist. This combination works great!

I'm printing a cold air intake system for my car from this stuff. 4mm think walls on 2 1/2" tubes are as strong as I could buy in anything below aluminum. And the temp resistance is high enough that it's only ever going to be an issue if my car catches fire. Good stuff, highly recommended.
