CarbonX PEEK+CF10
CarbonX PEEK+CF10 is one of the premier polymers in FFF/FDM 3D Printing. Made using 10% high-modulus chopped carbon fiber for exceptional stiffness, strength, and dimensional stability.
PEEK+CF10 is one of the highest performance thermoplastics ever invented. It is used in some of the most demanding applications by industries such as Auto, Aerospace, Defense, Semi-conductor, and Oil/Gas. Engineers depend on PEEK for applications where failure is not an option.
PEEK is an advanced, ultra-high-temperature polymer that demands industrial printing conditions to achieve consistent results. Plan on a 360–450°C hot end, 120–160°C bed, and a fully enclosed, actively heated chamber (70–150°C) to control warping and ensure strong layer adhesion. Best practices also include thorough filament drying, slow print speeds, and reduced or disabled part-cooling fan. Most standard desktop printers can’t reliably maintain these conditions.
For greater success, we recommend these high performance filaments:
PEKK: Delivers similar “PEAK-family” performance benefits but is often considered more forgiving to dial in than PEEK, with improved layer bonding and reduced warping sensitivity in many setups. It’s a strong step toward PEEK-level capability without as much process difficulty.
ULTEM™ (PEI): A high-performance polymer that typically prints more predictably than PEEK while still offering excellent heat resistance and strength. It’s a great choice when you want industrial-level performance with a more manageable processing window.
PPS: Known for strong chemical resistance and dimensional stability, and it can be an easier path to consistent parts compared to PEEK. It’s a smart option for environments involving fuels, solvents, or harsh chemicals where reliability matters.
MADE IN THE USA
We manufacture all of our filaments in our 68,000 ft² manufacturing facility (located in Grand Rapids, Michigan) using state-of-the-art equipment and processes. Our goal continues to be to make the most innovative filaments on the market – targeting difficult end-use applications.
