CarbonX™ PEEK+CF20 is one of the premier polymers in FFF/FDM 3D Printing. Made using 20% high-modulus chopped carbon fiber for exceptional stiffness, strength, and dimensional stability.
PEEK is one of the highest performance thermoplastics ever invented. It is used in some of the most demanding applications such as seals, gears, bushings, bearings, and pump & compressor components. Industries such as Auto, Aerospace, Defense, Semi-conductor, and Oil/Gas depend on PEEK for applications where failure is not an option.
CarbonX™ PEEK+CF20 Properties Include:
PEEK has an excellent resistance to hydrolysis in boiling water and superheated steam (sterilization/autoclave) at temperatures in excess of 250°C (482°F).
General thermal properties of PEEK+CF20 are:
CarbonX™ CF-PEEK is carbon fiber reinforced and abrasive - resulting in high wear on a brass nozzles. We recommend a 0.4mm orifice or larger. We strongly recommend our Hardened Steel Nozzles
Printing with CarbonX™ PEEK+CF20
PEEK has a melt temperature (Tm) of 343°C, therefore, you will need an all-metal extruder capable of reaching (and holding) temps upwards of 400°C or more depending on your specific printer. Every printer / slicer is different and you will need to tinker a bit to find a process that works for you. One of the more difficult aspects of printing with PEEK was getting it to stick to the build plate. We developed Nano Polymer Adhesive specifically for PEEK, in the beginning!
Here are our recommendations - which should act as a good starting point for you and your particular set-up.
