CARBONXTM CF-PEKK-A 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 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.

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

Recommended Print Settings:

• Extruder: 360-390°C
• Bed Temp: 120-140°C
• Nozzle: We currently recommend using one of our abrasion-resistant Vanadium™ 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
