What can you expect?
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.
You can inspect the parameters of every spool we made at prusament.com. Check the sample spool!

Manufactured In-House By Josef Prusa
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament 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.

± 0.04 mm Manufacturing Guaranteed Precision
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.

High Quality You Can Check Yourself
We 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).

About PC Blend Carbon Fiber
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.
Print preparation
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 (available in drugstores, for example) 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.

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.Filament color
Preparation time: 1-3 business days.
