CarbonX™ CF-PEKK 3D Printing Filament

CarbonX™ Carbon Fiber Reinforced PEKK 3D Filament

CarbonX™ CF PEKK-A [Aerospace] Printing Filament

CarbonX™ Carbon Fiber PEKK-A (PolyEtherKetoneKetone) aerospace-grade performance is made possible using PEKK (60/40 copolymer) and Toray T-800 aerospace-grade chopped carbon fiber.  This combination makes for one of the highest-performance polymer compounds in world. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK.

The premium Toray® Aerospace-Grade carbon fiber reinforcement makes this a compound purpose built for extreme applications which require extreme thermal, mechanical, and chemical resistance properties. CarbonX™ PEKK products have a lower melt temperature as well as lower rate and degree of crystallinity than PEEK, which aids in the remarkable ease of printing.

Benefits of CF PEKK-A [Aerospace] Includes:

  • Substantially easier to 3D print than PEEK
  • Wide processing window from 345-375°C
  • Tg of 160°C, HDT of 150°C, and a Tm of 305°C
  • Inherently flame resistant (UL94 V-0)
  • Low smoke generation
  • Outstanding mechanical, thermal, and chemical resistances

Filament Specifications:

1.75mm +/- 0.05mm in diameter

Recommended Print Settings:

  • Extruder: 360-390°C
  • Bed Temp: 120-140°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, up to 140°C if at all possible.
  • Supports: ThermaX™ HTS High-Temp Support is designed to work with complex, high-temp materials like this
  • Drying Instructions: 120°C for 4 hours





A premier polymer – one of the highest performance thermoplastics ever invented.

PEEK is an ultra-performance filament, ideal for the most demanding functions in Aerospace, Automotive and Electronic applications. This is possible as it has incredible mechanical properties, excellent strength and durability, resistance to corrosion and temperatures, and flame retardancy. It can withstand boiling water and steam.

Printing with this material is very difficult and requires a significant amount of experience in 3D printing. A high quality or heavily modified printer is mandatory.
