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.

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
