Features

  • Excellent Stiffness & Strength - Featuring a tensile modulus up to 8.4 GPA on the XY axis and 3.7 GPA on the Z axis, Fiberon™ PA6-CF20 is well suited for high performance industrial and engineering applications. Fiberon™ PA6-CF20 combines extreme stiffness and best-in-class tensile strength. Fiberon™ PA6-CF20 is an excellent choice for dry applications[1] requiring stiffness and durability such as automotive brackets, jigs, ESD safe fixtures, aerospace, prosthetics and engineering.
  • Excellent Heat Resistance - Featuring a high heat resistance up to 215°C after annealing[2], Fiberon™ PA6-CF20 offers excellent heat resistance for demanding applications where heat and stress are critical design factors. This material lends itself perfectly to functioning automotive applications where a combination of heat resistance and mechanical properties are required. 
  • Outstanding Layer Adhesion - Most fiber reinforced materials show a decrease in z-axis layer adhesion when compared with their non-fiber reinforced Nylons, producing a part that is only stronger on the X-Y axis but detrimental to the Z axis. Polymakers new technology in Fiberon™ PA6-CF20 not only solves this problem but actually increases Z axis tensile strength creating more isotropic parts that are strong in every direction.
  • Warp-Free™ - Fiberon™ PA6-CF20 features Polymakers Warp-Free™ technology to deliver a reliable Nylon filament with excellent dimensional stability and near-zero warpage. This is achieved by the fine control of microstructure and crystallization behaviour of Nylon, which enables the material to fully release the internal stress before solidification. The Warp-Free™ technology in Fiberon™ PA6-CF20 is designed to work best with minimal bed temperatures.
  • Wear Resistant and Tough - Parts printed in Fiberon™ PA6-CF20 display excellent toughness and wear resistant properties.
  • Improved Printability – Unlike many other Nylon filaments, Fiberon™ PA6-CF20 is extremely easy to work with, exhibiting excellent dimensional stability. It is compatible with most filament-based 3D printers with no heated bed or chamber required!
  • Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.

[1] Most Nylon parts in the real world undergo a process called "Moisture conditioning" which improves toughness and flexibility of the Nylon while reducing tensile strength and stiffness. Unless protected with a moisture barrier, PA6-CF shows a greater change in mechanical properties when subjected to water / high humidity in comparison to long-chain nylon filaments like PA12-CF or PA612-CF. In simple terms PA6-CF will typically offer the best properties in a dry application, but for a wet or high humidity application a longer chain nylon such as PA612 or PA12 may be better. See "Specifications & FAQ" tab to learn more about what moisture conditioning is, how it works and if it's relevant to your application.
[2] Fiberon™ PA6-CF20 displays the best mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization during the printing process, an additional step is required: Annealing. Fiberon™ PA6-CF20 can be annealed in the oven at 100˚C for 16 hours right after the printing process.

Technical Data

All PA6-CF20 specimens were printed with 300°C nozzle temperature, 50°C bed temperature, cooling fan OFF. Samples were printed with 100% infil, 2 shells and 3 top & bottom layers.

All samples were annealed after printing at 100°C for 16h.

Nylon is a semi-crystalline material, it's crystalline regions offer many properties, but in particular their structure deliver the heat resistance that nylon is known for. Annealing after printing is a critical process to achieve consistent crystallinity and complete the production process of nylon parts.

Mechanicla Properties

Dry state represents when PA6-CF20 part is printed and annealed.
Wet state represents if the PA6-CF20 part were submerged in water for 48 hours.

If your part is exposed to reasonable humidity (70% RH) but isn't exposed to water, your part would become moisture conditioned. To enter the wet state would require very high humidity, steam or submersion.

Nylon 6 based materials are moisture sensitive and their mechanical properties change. As they absorb moisture the toughness and flexibility increase, while tensile strength and stiffness decrease. This process is not permanent, if the part were dried, it would regain strength and stiffness.

Well made, looks sharp.
Size: Large, Color: Blue, Size: Large, Color: Blue
I picked this up to have another nicer dress shirt. It's made of quality materials. I thought I should have it a little less big than I normally get so I sized down and that was a mistake. That's my fault though. Luckily it fits my wife so she's taking ownership. It fits true to size. The material feels good on your skin. It doesn't have that sheer look that a lot of of button up shirts do. It is is nice and thick. At twenty five dollars it's a good price.

fits well
Size: Large, Color: Blue
wanted a classic-looking western shirt to add to my wardrobe, and this embroidered button-down really caught my eye. The bright and bold white embroidery stands out beautifully against the dark blue fabric of the shirt. It gives off a very traditional cowboy vibe without feeling outdated or tacky. When I tried it on, I was glad to find that it fits comfortably across the shoulders and chest without feeling overly restrictive. The long sleeves are a great length, and the fabric feels durable enough for casual day-to-day wear. It works perfectly whether you want to tuck it in for a neater look or leave it untucked for something more relaxed. The buttons are secure, and the overall construction feels solid throughout. It is a striking shirt that strikes the right balance between style and everyday comfort.

Western Prop Top
Size: Small, Color: Blue
This is a nice western shirt, especially if you’re looking for something for a costume or themed event. It has that classic cowboy look with the embroidered details, which give it a bit of style without being too over the top. The fabric feels decent, it’s soft and comfortable while wearing it. It’s not premium-level, but it gets the job done for the price. The fit and design work well with jeans or boots, making it easy to pull together a full western outfit for a party, concert, or rodeo-type event. Overall, it’s a solid option if you want a good-looking western shirt without spending a lot, especially for occasional wear or costumes.

A very comfortable shirt at a good price!
Size: Large, Color: Blue
Comes out very soft once washed! I ordered this shirt when I saw it and was curious how stiff the material was. I was expecting something a bit more coarse since it was western wear, but was pleasantly surprised to find that once washed it became very soft. The shirt is also very light and airy, and allows the breeze through to cool you off. I was also impressed with the quality of the shirt. All the stitching is tight and neat, and there were no threads hanging loose to catch on anything. As far as sizing goes, it was exactly what they recommended based on measurements, and it fits great. The cut of the shirt is pretty nice also with a bit of a taper, and it looks really good on (according to my wife, anyway). The shirt is versatile enough to wear out to dinner at the steakhouse, or to work in the yard. Bottom line: The shirt is comfortable, fits well, is good for work or going out, and a great deal for the money!

Looked amazing… but not built for broader shoulders
Size: Small, Color: Blue, Size: Small, Color: Blue
I got this for my husband because he’s fully leaning into his cowboy era lately (new boots, new attitude, the whole thing), and I thought this shirt would seal the deal. First impression—honestly impressed. The color is really nice and the embroidery detail looks great in person. It doesn’t feel cheap at all and definitely looks more high-end than expected. For reference, he’s about 5’6”, 140 lbs with an athletic build. The shirt almost worked—it fit well through the body and could be fully buttoned, but the shoulders were just too tight. As soon as he moved his arms, it felt restrictive, like the seams were being pushed to their limit. Which is a shame… because wow, he looked GOOD in this. And that’s coming from someone who doesn’t usually love this style. I’d say this shirt runs better for slimmer or narrower builds. If you’ve got broader shoulders or any upper body muscle, you may want to size up or skip this one. Overall, great quality and style, just not the right fit for an athletic frame.
