CarbonX™ PEEK+CF20 Ultra Polymer is formulated using 20% chopped carbon fiber and Victrex PEEK resin. Our PEKK+CF20 offers exceptional thermal properties [up to 280°C] as well as outstanding mechanical and chemical resistance properties.


Typical PEEK+CF20 Applications Include:

Seals, Gears, Bushings, Bearings, Pump, and Compressor Components

Industries served: Auto, Aerospace, Defense, Semi-conductor, Oil & Gas

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, and printing environment is different and you will need to tinker to find a process which works for you. One of the more difficult aspects of printing with PEEK was getting it to stick to the build plate.

Please note: PEEK+CF20 has a tendency to stick to metal (PEEK loves metal).  Make sure to purge out your extruder completely before it cools down or you run the risk permanent clogs. Seriously, we know this first hand.

Filament Specifications:

1.75mm and 2.85mm +/- 0.05mm in diameter

Recommended Print Settings:

  • Extruder: 385-415°C
  • Bed Temp: 130-150°C
  • Nozzle: We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm.
  • Other: Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers smaller than 0.2mm with carbon fiber reinforced filaments.
  • Bed Prep: Nano Polymer Adhesive or 3DXTECH Polyimide Tape gives us the best results
  • Heated Chamber: Recommended
  • Supports: ThermaX™ HTS High-Temp Support was specially designed to work with complex, high-temp materials like this.
  • Drying Instructions: 120°C for 4 hours.
