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 the world.

A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also substantially easier to print than PEEK.

DESCRIPTION +

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:

CARBONXTM CF-PEKK-A filament is 1.75mm +/- 0.05mm in diameter

Abrasive Material

PEKK's material properties are particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.

Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal, making our GammaMaster® Nozzles an excellent choice for this material.   

Technical Data Sheets and Safety Data Sheets can be located here.


Recommended Print Settings +
  • Extruder: 360-390°C
  • Bed Temp: 120-140°C
  • Nozzle: We currently recommend using one of our abrasion-resistant GammaMaster® Nozzles 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
