Fiberon™ PET-CF17: High-Performance Carbon Fiber Reinforced PET Filament
Engineered for Strength and Precision
Fiberon™ PET-CF17 is a carbon fiber reinforced PET (polyethylene terephthalate) filament, specifically designed for engineering-grade 3D printing. With 17% carbon fiber content, it delivers a high modulus for excellent stiffness and dimensional stability, making it ideal for functional prototypes and end-use parts.
Key Performance Features
- High Modulus & Strength: The carbon fiber reinforcement provides outstanding rigidity and mechanical strength, suitable for demanding engineering applications.
- Heat Resistance: Maintains structural integrity at elevated temperatures, making it suitable for parts exposed to heat or requiring thermal stability. Annealing is required for higher heat resistance.
- Moisture Insensitivity: Unlike many engineering filaments, Fiberon™ PET-CF17 is less sensitive to moisture, ensuring consistent print quality and reducing the need for pre-drying.
- Easy to Print: Offers smooth extrusion and reliable bed adhesion, making it accessible to users with standard high-temperature FDM/FFF 3D printers equipped with a hardened nozzle.
Ideal for Engineering Applications
Perfect for automotive, aerospace, robotics, and industrial parts where strength, durability, and precision are essential.
Choose Fiberon™ PET-CF17 for your engineering projects when you need a composite material that combines high strength, heat resistance, moisture insensitivity, and reliable, easy printing.

Technical Specifications
Everything you need before you hit print
- Use an all-metal hotend within 270-300°C and a wear-resistant nozzle because the carbon-fiber reinforcement is abrasive.
- Dry at 100°C for 10 hours and keep the filament dry during use.
- An enclosed printer is recommended; keep the chamber door closed during printing.
- For the annealed performance stated in the TDS, anneal at 120°C for 10 hours.
- Before annealing, allow the print to rest for more than 24 hours or place it at 80°C for 2 hours; do not apply load and keep the oven temperature uniform.
- Retain supports for bridges or overhangs and reinforce thin walls when deformation is a concern.

Customers praised this carbon fiber filament as "easy to print" with "exceptional strength" and a "smooth surface finish that hides layer lines." Many called it their favorite for functional parts. Some noted it requires drying and has weak Z-axis layer adhesion. A few mentioned brittleness and low impact resistance, with one reporting extreme bed adhesion issues.
PET-CF is a really great engineering filament, especially considering the price. It’s surprisingly easy to print and gives very consistent results. The mechanical properties and overall quality are excellent, making it a great choice for functional and technical parts.
Consistent and worry-free filament. Fiberon pet-cf17 is my new favorite CF filament.
Well packed, quick shipping, quality product resulting in quality functional prints.It's not cheap,but when it comes to printing parts you rely on,you gget what you pay for.
I was worried these large spools would be trouble, but I was wrong. They have worked out better than I thought they could! I print a lot of large files. Being able to print several parts back to back without having to change the spool has been a huge blessing! Will be ordering more very soon!
Great product. Worked as expected.
This filament prints like pla but is insanely strong. It comes off the printer perfectly when using their settings on my p1s. Ive printed with it all day at times and each print came out the same. Its by far my favorite CF filament!
I ordered this stuff because I wanted to print a new handle for our Big Green Egg. The original handle had seen better days, and of course I needed something that would have a lot of heat resistance, so I went for the PET-CF17. Both things printed here were done on a Bambu Lab A1 using a 0.4mm hardened hotend with a Darkmoon3D Satin build plate, and it pretty much runs at the limit of the hotend, printing at 300C. These prints were straight out of the package, no drying time. I did place the spool in a drybox that I'm printing from.I first printed a Benchy, which as you can see came out about as nicely as any I've seen. Zero stringing, bridging was perfect, no layer shifts, etc. All the good things you're looking for. Also shown is the new handle on the Egg, alongside the old one. The big handle warped a tiny bit, but once I screwed it in place, it straightened right out. I'm confident that if I was running an enclosed printer, or maybe went up to 75 or 80C on the bed that it would be perfect.
PET17CF is my favorite Fiberon filament. It prints perfectly and is very strong.
Livraison efficace, produit de très bonne qualité
used for a d class model rocket. performed great.
Produit top comme toujours avec Fiberon et Polymaker
Well packed.... Great products... Will order again
Love it!
Relatively poor layer adhesion due to the high carbon fiber content. Sticks extremely well to my PEI coated bed, so much so that I destroyed the coating trying to get the brim off of my latest print.
Fiberon PET-CF17 is one of my favorite materials. I made some brake levers for my moped out of this stuff and I have been extremely pleased with the results. Compared to nylon this is definitely stiffer, it has very minimal flex. It can be a little brittle though. If your part is prone to flexing, this is not the best choice of material. The moisture absorption is definitely much lower than nylon BUT it does require drying before use for a nice surface finish.
It very strong in xy axis. very weak in z axis. needs to be annealed if it's going to be exposed to temps over 90-100c. Impact resistance is verylow.
Got an amazing deal on this with Polymaker’s 35% off discount. Shipped fast anfd recieved in two days. Filament orints very smooth on my Bambu A1 with no enclosure.
Fiberon PET-CF17 is AWESOME!
3kg spools are great.
Easy to print. Very strong and has a nice finish that hides layer lines. Must be kept very dry.
This filament prints excellent on my Bambu A1 without an enclosure to create an exceptional strong print with a very smooth surface. Absolutely love it!!
Outstanding filament. Very wear resistant and good for mechanical prototyping.
Love this stuff, its my preferred filament for structural parts
By far my favorite high strength filament with a beautiful smooth finish. Rock solid. Prints with a challenge onna Bambu A1 without an enclosure. Make sure its dry and run the nozzle at 290 C, dont exceed speeds of 80 mm/s to ensure good layer adhesion.
Easy to print with and makes good looking parts. Be worn though you do not get high temp resistance unless you anneal the parts. When an annealing it can warp. Especially with larger parts.
Great high performance material for all around use. Rigid, Strong, Prints easily, High temperature resistance, great price. Pretty much my default for functional parts.
Can’t wait to try this filament. Polymaker is awesome.
Quality as always. Suggest a 0.6 nozzle to avoid clogs.
Prints like PLA
