3DXTech FibreX™ PEKK-A 1.75mm 500g

    One of the PAEK family of high-performance polymers, FibreX™ PEKK-A by 3DXTech has a lower processing temperature than PEEK which makes it easier to print, and after annealing can display even better mechanical, thermal and chemical resistance properties.

    FibreX™ PEKK-A by 3DXTech utilises one of the highest performance polymers available today (PolyEtherKetoneKetone) to create a filament with mechanical, thermal, and chemical resistance comparable to PEEK, but as it requires lower processing temperatures it is significantly easier to print. After an annealing process, PEKK-A has been shown to out-perform PEEK in many areas, making it a more reliable alternative material for industrial applications.

    Key Features:

    • Made with 60/40 PEKK copolymer
    • Easier to print than PEEK
    • Inherent flame resistance (UL94 V-0)
    • Good chemical resistance, including alcohols, automotive fluids and aqueous solutions
    • Low smoke generation - ideal for aerospace applications
    • Outstanding mechanical, thermal, and chemical resistance

    Annealing PEKK-A Printed Parts

    Annealing PEKK-A is optional, however it can post-crystalise the material and improve the mechanical, thermal and chemical resistance properties of the printed part. For example, the maximum use temperature can increase from 150°C to 260°C.

    1. Place part in an oven and raise the temperature to 160c, allow to remain at that temperature for 30 minutes.
    2. Raise the oven temperature to 200c and allow the part to remain their until it turns a uniform tan color. Timing will depend on the temperature uniformity and circulation of the air inside the oven. Allow to cool prior to handling part.
