    ThermaX™ PEKK-A 3D Filament

    ThermaX™ PEKK-A (PolyEtherKetoneKetone) is made using the 60/40 PEKK copolymer and is one of the highest performance materials in the plastics business.  PEKK is a leading material in the PAEK family and has exceptional mechanical, thermal, and chemical resistance properties, while being substantially easier to print than PEEK.  Developed in partnership with Arkema - a leading supplier of ultra-performance materials.

    The Polyaryletherketone (PAEK) family of thermoplastics exhibit exceptional thermal, chemical, and mechanical properties.  The PAEK family includes the following polymers:

    • Polyetherketoneketone (PEKK)
    • Polyetherketone (PEK)
    • Polyetheretherketone (PEEK)
    • Polyetherketoneetherketoneketone (PEKEKK)  

    Gone are the days when you needed a wildly expensive closed-source printer and license to take advantage of ultra-performance polymers.  Our PEKK was created to be printed using the many new open-source printer platforms currently available on the market.  Compare to Stratasys® Antero™ PEKK and you will realize this is a great opportunity to take advanced of an aerospace-grade material without being tied to an expensive closed-source system.

    3DXTech® and Stratasys® both purchase PEKK resin from the same supplier, so what's the difference?  Freedom, cost, and innovation.  ThermaX™ PEKK can be printed on a growing array of lower-cost printers whereas the Stratasys Antero™ PEKK requires users to purchase an expensive Fortus® system and a high-priced license.  

    ThermaX™ PEKK-A has a wider processing window than PEEK and typically prints with extruder temps between 325 - 350°C, whereas PEEK often requires extruder temps of 400°C or higher.  ThermaX™ PEKK has a lower rate and degree of crystallinity than PEEK, which aids in its ease of printing.  However, once printed and annealed, PEKK parts exhibit superior performance vs. PEEK.  Easier to print + superior performance!

    ThermaX™ PEKK product attributes include:

    • Substantially easier to print than PEEK
    • Continuous Use Temperature (CUT) of 260°C, and higher for short duration
    • Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)
    • Melt Temp (Tm) of 335°C  (allows for lower print temps than PEEK)
    • Inherent flame resistance (UL94 V-0)
    • Low smoke generation for aerospace applications
    • Outstanding mechanical, thermal, and chemical resistance
    • Excellent resistance to a broad range of chemicals, such as those used in the oil/gas, automotive, aerospace, industrial, and chemical processing industries
