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. 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.
