  • Detail

    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.
