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
