ThermaX™ PEKK-A (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK [60/40 copolymer] and is one of the highest performance materials in the world while also being one of the easiest to print ultra-polymers.
ThermaX™ PEKK-A 3D Printer Filament
ThermaX™ PEKK-A (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK and is one of the highest-performance polymers in plastics business. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK, it’s one of the easiest ultra-polymers to 3D print period. Developed in partnership with Arkema, a leading supplier of ultra-performance materials.

Benefits of ThermaX™ PEKK-A Include:
- High thermal properties with a CUT of 260°C, Tg of 162°C, and a Tm of 335°C
- Substantially easier to 3D print than PEEK
- Wide processing window from 345-375°C
- Inherently flame resistant (UL94 V-0)
- Low smoke generation
- Outstanding mechanical, thermal, and chemical resistances
Compare Our PEKK-A to Stratasys® Antero™ PEKK
- Both use real PEKK from Arkema as the base resin component
- ThermaX™ PEKK-A is a lower cost and specially designed for use on lower-pricepoint, open-material 3D printers
- Stratasys® Antero™ is more expensive and requires users to purchase an expensive Fortus® system and a high-priced user license
Filament Specifications:
1.75mm and 2.85mm +/- 0.05mm in diameter
Recommended Print Settings:
- Extruder: 345-375°C
- Bed Temp: 120-140°C
- Bed Prep: Nano Polymer Adhesive or 3DXTECH Polyimide Tape gives us the best results
- Heated Chamber: Recommended, heated to 70-150°C if at all possible
- Supports: ThermaX™ break-away HTS High Temp Support works ideal for complex, high-temp materials just like this
- Drying Instructions: 120°C for 4 hours
Stress Relieving 3D Printed Parts:
Parts printed with PEKK may be stress relieved after printing to reduce printed-induced stresses and increase the mechanical properties, dimensional stability, and chemical resistance of the printed part. This process does not anneal or induce crystallinity in PEKK-A since this is a mostly amorphous version of PEKK. If your intention is to anneal and induce crystallinity, then we suggest using our ThermaX™ PEKK-C filament that is made out of the 70/30 PEKK Copolymer.
Stress Relieving Process
- Place your part in a room temp oven and raise the temperature to 130°C and hold for 30 minutes per mm of wall thickness. Let it cool completely before handling.
