Prusament PA11 Carbon Fiber Black 800g (NFC) – Multipack 10 pcs

About PA11 Carbon Fiber Black

Prusament PA11 (Nylon) Carbon Fiber is an ideal filament for prototypes in the automotive, aerospace, and hobby industries, given its excellent resistance to heat, chemicals, and mechanical stress. Among the Prusament filaments, PA11-CF has by far the best temperature and chemical resistance. 3D-printed parts withstand up to 190 °C (depending on stress) and have increased resistance to many solvents (NaOH, Methanol, Ethanol, Toluene, Acetone, motor oils, benzene, diesel, etc.). PA11-CF is a material made from castor oil, the carbon fibers used for this material are recycled, the same as for the Prusament PC Blend Carbon Fiber. The best use of the PA11-CF is for making special chemically, mechanically, and heat-stressed parts, such as car engine components.

Printing Setup

• Nozzle - 285±10 °C
• Heatbed - 110±10 °C
• Recommended Steel Sheet - PA Nylon

Check Prusa's material table and print-surface preparation instructions before starting.

Basic Attributes

• Excellent temperature resistance (up to 190 °C) - A special print sheet (or separation layer) is required
• Great chemical resistance - Requires hardened nozzle
• High impact and wear resistance (very strong and rigid material) - Lower layer-to-layer adhesion compared to pure PA11
• Low friction coeficient - Slightly hygroscopic (absorbs moisture)
• Noticeably less hygroscopic compared to other polyamides - Emits odors during printing
• Visually appealing matt black surface
• Great dimensional stability – possible to print large models without an enclosure
• Uses recycled carbon fibers from the manufacturing process

New spools equipped with OpenPrintTag

Prusament filaments are wound on a redesigned spool that introduces several improvements for an even better printing experience, starting in October 2025. The new spool features a simple locking mechanism that makes disassembly quick and easy, allowing effortless refills. It also stays secure during filament drying, even at higher temperatures. And with its slimmer dimensions, the spool ensures compatibility with a wide range of multi-color and multi-material printing systems.

Every new Prusament spool now comes with a fully rewritable NFC tag powered by the OpenPrintTag standard. It’s designed to work across brands and ecosystems. It is free to use, free to extend, and open for anyone to build upon. Most importantly, it works entirely offline. All essential data is stored directly on the tag. Your printer can recognize the spool instantly, with no dependence on cloud services or vendor lock-ins. The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app.

What can you expect?

Prusament PA11 Carbon Fiber Black is our own in-house made Polyamide filament filled with carbon fibers. The whole manufacturing process is closely monitored and tested - we guarantee ±0.04mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com.

Prusament is produced by Prusa Polymers, with manufacturing checks throughout production.

Premium-Grade Materials And Thorough Testing The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.

Prusa specifies a filament diameter tolerance of ±0.04 mm. Check the product notes for blend-specific tolerances.

We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.04mm precision and highly-consistent colors in our filaments.

Beginners tips & tricks

It is necessary to use a hardened steel nozzle. Carbon fibers are a highly abrasive material and may damage brass nozzles. Prusament PA11 Carbon Fiber Black can be printed onto textured or satin print sheets with a thin separation layer made with a glue stick (a separation layer is extremely important). However, the results may not be perfect. This is why we are introducing a new type of sheet - the Double-sided Powder-coated PA Nylon Satin Spring Steel Sheet which was designed specifically for Prusament PA11 Carbon Fiber Black. If you are using the new PA Nylon Satin sheet, never clean it with IPA, acetone, or other solvents - the surface will deteriorate quickly. Instead, clean the sheet with water only (a drop of dishwashing detergent may be used to clean greasy areas). We recommend printing in a well-ventilated room because PA11 with carbon fibers may release a noticeable odor into the air and produce ultra-fine particles. Printing on an enclosed 3D printer helps contain the odors and particles, plus the increased temperature may improve layer-to-layer adhesion. PA11, like other polyamides, is a hygroscopic material (it absorbs air moisture). If the absorbed humidity reaches high values, the print quality will deteriorate. Deterioration occurs after a few days to a month, but if you are unsure or know you have not printed for a long time, we recommend drying the filament at 90°C for 4-6 hours before printing. You can find more in-depth printing tips in our article at blog.prusa3d.com and in our Material table.

Notes

Prusament PA11 Carbon Fiber Black is made in-house by Prusa Research. 1.75 mm filament is manufactured with a precision of ±0.04 mm. Carbon fibers inside the filament are made by recycling waste from the manufacturing process or from carbon composites after the end of their lifespan.

To dry the filament, please follow the instructions in our article.
