CarbonX PEEK+CF20

CarbonX PEEK+CF20 Carbon Fiber Reinforced Filament

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+CF20 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.

 

CarbonX™ PEEK+CF20 Properties Include:

Superior mechanical properties, even at elevated temperatures

Excellent chemical resistance

Low Coefficient of Linear Thermal Expansion (CTE)

Near Zero moisture absorption

Low smoke and toxic gas emissions

 

PEEK+CF20 Thermal Properties:

Heat Deflection Temperature (HDT) of 320°C

Glass Transition Temperature (Tg) of 143°C

Melt Temperature (Tm) of 343°C

PEEK has an incredible resistance to hydrolysis in boiling water and superheated steam (useful for sterilization and autoclaving) at temperatures in excess of 250°C

 

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 firsthand.

 

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

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.
