PEKK (PolyEtherKetoneKetone) is one of the highest-performance polymers in world. A leading material in the PAEK family, PEKK 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.
ThermaX™ PEKK product attributes include:
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 has a wider processing window than PEEK and typically prints with extruder temps between 340 - 360°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!
Recommended Print Conditions:
Annealing (post crystalizing) 3D Printed PEKK Parts: Parts printed with PEKK may be annealed after printing to ramp-up the crystallinity in the resin. This will maximize mechanical, thermal, and chemical resistance properties. Printed parts will be transparent golden in color and then turn an opaque tan color once annealed (see picture above).
