3DXTECH CARBONX PEEK+CF20

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

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. Right now, we are loving the Hardened Steel Nozzles, as well as Tungsten Carbide nozzles
• 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 NorthPrint3D bed Adhesive
• 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.
