Prusament PC Blend Carbon Fiber Black 800g

What can you expect?

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.

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

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.

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.

I print with a lot of not so common materials like PP, PVC and Nylon CF. The Prusament PC CF blend is the easiest to print of all and priced at the low end compared to the other materials! Surface finish and part stability are excellent.

10 out of 10 would recommend I have a ruby tip nozzle and the MMU2S, I have printed my thesis (propellers), using this material and HIPS, dissolved the HIPS did not treat the material, ran it in the Wind tunnel and analysed several results, I hope this helps someone who is deciding to buy this product in the future to know it’s capability and durability

Easily the most stable and consistent filament I have ever printed with. It does not warp at all, looks great, and is generally very easy to work with as long as you stick with the default slicer settings. Only downside is that the filament clogs rather easily - the preset in PrusaSlicer for this filament is right on the edge and will work most of the time, but if you increase parameters like flow rate, extrusion width etc. even very slightly, it will almost certainly clog. I currently print this filament on a 0.4 synthetic diamond nozzle, and the normal procedure for removing clogs works well, i.e. heating the nozzle to 290°C (and unloading the filament), poking through the clog from below with an acupuncture needle (the one that came with my MK3S+), using special cleaning filament to push through the clog, and finally performing a cold pull using cleaning filament. That clears the nozzle fully and I can print with it again. Do keep in mind that if you use the E3D V6 Nozzle-X you probably are out of luck because both using a needle and doing a cold pull (necessary to get stuck filament pieces out) is against that nozzle's warranty and may damage it.
