Fiberon™ PA12-CF10

Professional-Grade Mechanical Strength and Dimensional Stability Fiberon™ PA12-CF10 is a carbon fiber reinforced long-chain copolyamide (PA12) filament engineered for demanding industrial and engineering applications. With 10% carbon fiber content, it delivers outstanding mechanical strength, rigidity, and thermal resistance, making it ideal for parts that require durability, precision, and minimal warping.

Low Moisture Sensitivity Thanks to its advanced chemical structure, Fiberon™ PA12-CF10 absorbs significantly less moisture than PA6/66 and PA6-based materials. This ensures consistent dimensional accuracy and mechanical properties, even in humid environments.

Enhanced Properties Over Standard PA12Fiberon™ PA12-CF10 outperforms standard PA12-based filaments in both strength and heat resistance, providing a reliable solution for functional prototypes, end-use parts, and manufacturing tools.

Warp-free™ Technology This filament incorporates Warp-free™ technology for excellent dimensional stability and minimized warping, even on large or complex prints.

Consistent Quality Fiberon™ PA12-CF10 uses the same trusted formula as PolyMide™ PA12-CF, though prints may appear in a slightly darker black shade.

Choose Fiberon™ PA12-CF10 when you need a filament that combines high strength, low moisture sensitivity, and excellent dimensional stability for advanced engineering and industrial 3D printing.

Printing Tips

This material has a requirement that you print with an all metal hotend that can reach 280˚C or higher as well as the need for a hardened nozzle.

• Do not set your build plate above 50˚C and keep any chamber doors open. If you let the build plate or ambient air get above 50˚C, you run the risk of warping or ugly prints.

• Use a glue stick or Magigoo PA if experiencing any issues with bed adhesion.

• PA-CF is very hygroscopic and therefore should only be printed while kept in a heated filament dryer the entire time you print.

• If you hear "popping" or "cracking" noises, then the filament needs to be dried.

• This needs to be annealed after printing at 100˚C for 16 hours.

• After annealing - the part will be dried out and therefore need to be moisture conditioned.

• Moisture conditioning will happen even if you do nothing as the material absorbs moisture from the air. To speed up moisture conditioning, keep in a humid environment for 48 hours.

FAQ

What is annealing?

You can find out more about annealing HERE.

What is moisture conditioning?

Moisture conditioning refers to allowing the print to absorb moisture. This is inevitble since nylons are hygroscopic, but you can expedite the process by keeping the print in a high humidity climate, or submerging them in water, for 48 hours. All of our test specimens were annealed at 100˚C for 16 hours, and then immerged in water at 60˚C for 48 hours. The average moisture content of specimens is 2.57%.

Should I anneal before or after moisture conditioning?

IWhen you anneal in a convection oven, you will dry the part out. So if you moisture condition before annealing - you will need to moisture condition again after. So we would suggest to moisture condition after annealing.

Why do you use such a low build plate temperature with your nylons?

Our nylons come with our Warp-Free™ Technology. In order for this Warp-Free™ technology to work as it should - we want to make sure the build plate and the ambient air temperatures are both below 50˚C. We then anneal the print after to get it's full strength.

Will the spools work in an AMS?

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

That said - you will need to be careful when using any abrasive materials in the AMS.

Do I need a filament dryer?

Yes, you will need a filament dryer when printing with nylons due to them being hygroscopic.

Can you make Fiberon spools in 1KG?

Unfortunately we are not offering 1KG Fiberon™ options and this has to do with the increased chance of carbon fiber and glass fiber filament snapping on the spool.

Since carbon fiber and glass fiber filament is more brittle, we spool these with a larger core. This larger core means that 1KG of filament will not fit on a 1KG spool. 3KG options of all Fiberon™ spools are available though.

Printing Requirements

• All-metal hotend 280˚C+
