Prusa Research Prusament PC Blend Carbon Fiber Black 800g
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 and toughness, but most importantly with high-temperature resistance.

About PC Blend Carbon Fiber
PCCF (Prusament PC Blend Carbon Fiber) has similar printing qualities to unmodified PC Blend but the addition of the carbon fibers makes it even stronger, more resilient, more temperature resistant, and dimensionally stable.
Unlike pure PC Blend, PCCF practically doesn’t warp and has a nice matte surface. Compared to other materials, PCCF has good resistance to UV light and common chemicals. The PCCF is slightly lighter than 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.
PCCF is ideal for printing mechanical parts and heat-stressed components, for example, various gears and machine parts requiring heat resistance over 100°C. Probably the greatest advantage of PCCF, compared to PC Blend, is the possibility of printing large models without the necessity of using a heated enclosure.
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.
