Prusament PC Blend Carbon Fiber (PCCF) is a PC Blend filled with carbon fibers to improve its strength, toughness, and temperature resistance. Unlike the unmodified PC Blend, PCCF comes with great dimensional stability, good resistance to UV light and common chemicals, better tensile strength, but most importantly with high-temperature resistance and easier printing. It is optimal for printing technical components requiring great strength and high-temperature tolerance. The possibility of printing large models without using an enclosure is a great advantage when compared to pure PC Blend. Printing with PCCF requires a hardened steel nozzle.
It is necessary to use a hardened steel nozzle. Carbon fibers are a highly abrasive material and may damage a brass nozzle.
Powder-coated or satin TXT sheet provides good adhesion. Clean it with IPA , which works great not only with PCCF but with other materials too.
Pour a small amount of IPA on a paper towel and use it for cleaning the surface. To achieve the best results, clean the surface while it’s cold. Keep in mind that higher temperatures will evaporate the alcohol before cleaning the surface. Also, don’t forget that the heatbed preheated for printing with PCCF has a high temperature (110 °C) and may burn you if you touch it! Another possibility is cleaning the surface with warm water and a few drops of dish cleaner on a paper towel. You can also use denatured alcohol.
We don’t recommend printing with PCCF on a smooth PEI sheet. This material adheres greatly to the PEI surface and may cause damage to it. This type of damage is not covered by the warranty. If you need to print on a smooth surface, spread a thin layer of paper glue stick on it.
Also, if you often print with PCCF on the satin sheet, we recommend using a glue stick to prevent surface wear-out.

Nozzle 285±10 °C
Heatbed110±10 °C
Recommended Steel Sheet Satin
Before printing, learn about print surface preparation in Prusas dedicated article and material table.
High impact and wear resistance (very strong and rigid material)
Great high-temperature resistance (up to 114°C)
Possibility of annealing (improving resistance up to 130 °C)
Good UV stability and resistance to common chemicals
Great dimensional stability – possible to print large models without an enclosure
No need for drying prior to printing
Visually appealing matt black surface
Uses recycled carbon fibers from the manufacturing process
Requires hardened nozzle
More brittle than Prusament PC Blend
Lower thickness precision (0.04 mm) caused by carbon fibers inside
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.
Prusament PC Blend Carbon Fiber (PCCF) is our own in-house made filament filled with carbon fibers. The whole manufacturing process is closely monitored and tested - we guarantee ±0.04 mm precision and highly-consistent colors.
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 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.
Prusa are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).
Beginners tips & tricks
It is necessary to use a hardened nozzle. Carbon fibers are a highly abrasive material and may damage a brass nozzle.
If you often print with PCCF on the satin sheet, we recommend using a glue stick to prevent surface wear-out.
Notes
Prusament PC Blend Carbon Fiber Black is made in-house by Prusa Research.
1.75 mm filament is manufactured with a precision of ±0.04 mm.
The PCCF is slightly lighter than the unmodified PC Blend, with approx. 5% difference.
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.
