PCCF (Prusament PC Blend Carbon Fiber) has similar printing properties to PC Blend, but thanks to the addition of carbon fibers, it has great strength, stiffness, and heat resistance, plus good dimensional stability.
Unlike pure PC Blend, it practically does not warp and has a really nice matte surface. Compared to most common materials, it is more resistant to UV radiation and common chemicals. Compared to classic PC Blend, PCCF is slightly lighter (approx. 5% difference).
The carbon fibers inside the filament are obtained by recycling waste from the production process or from carbon composites at the end of their life cycle.
PCCF is ideal for printing mechanically and thermally stressed parts, such as gears, machine parts requiring heat resistance over 100 °C, etc. A huge advantage of PCCF lies in the possibility of printing large models without the need for a heated chamber.
Preparation before printing
The use of a hardened nozzle is required. Carbon fibers are highly abrasive and can damage the interior of a classic brass nozzle.
For optimal adhesion, use a textured or satin print sheet. Clean them using IPA (available e.g. in pharmacies), which works well not only with PCCF but also with other materials.
Pour a small amount of IPA onto a paper towel and wipe the print bed with it. For the best cleaning effect, it is advisable to clean the bed when it is cold. At higher temperatures, the alcohol evaporates before it can clean the bed surface. Furthermore, the bed heated for printing with PCCF has a high temperature (110 °C) and you can get burned! Another option is to clean the surface with warm water and a few drops of dish soap on a paper towel. Denatured alcohol is another alternative.
PCCF is not suitable for printing on a smooth PEI print sheet. Printing PCCF on a smooth sheet risks irreversible damage, which is not covered by the warranty. If you need to print on a smooth surface, apply a glue stick before printing.
When printing PCCF very frequently on a satin print sheet, it is recommended to apply a layer of glue stick to reduce sheet wear.
