Product Details

3DXTECH 3DXSTAT ESD-PEKK-A 3D Printing Filament

Made using Arkema Kepstan® PEKK (PolyEtherKetoneKetone) and state of the art conductive additives, this ESD PEKK-A is one of the highest-performance polymers in world and ideal for demanding applications. This filament was created for the highest-spec situations where tightly controlled static dissipation, thermal properties, and mechanical performance properties are required.

Benefits of PEKK-A Include:

  • Substantially easier to print than PEEK, made using 50/40 type PEKK copolymer known as PEKK-A
  • High thermal properties with a Tg of 162°C, HDT of 150°C, and Tm of 305°C
  • Inherently flame resistant and self-extinguishing
  • Long-term hydrolytic stability making it ideal for steam and autoclave environments
  • Excellent dimensional stability with low heat creep, low and uniform coefficient of thermal expansion, and highly reproducible part-to-part dimensions
  • Exceptional strength and modulus, even at high temperatures
  • Excellent resistance to a broad range of chemicals, such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
  • Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Benefits of 3DXSTAT™ Include

  • Consistent surface resistivity
  • Improved retention of impact & elongation
  • Low particulate contamination
  • Minimal contribution to outgassing and ionic contamination

Compare 3DXSTAT™ ESD PEKK-A to Stratasys® Antero™ PEKK 840CN03:

  • Both use real PEKK-A from Arkema as the base resin component
  • Both use carbon nanotubes as the conductive additive
  • 3DXSTAT™ ESD PEKK-A is lower cost and suitable for use on lower-pricepoint, open-material 3D printers
  • Stratasys® Antero™ 840CN03 is more expensive and only available on the ultra-expensive Fortus® 900mc Plus

Typical ESD PEKK-A Applications Include:

  • Semi-con: HDD Components, Wafer Handling, Jigs, Casings, & Connectors
  • Industrial: Conveying, Metering, and Sensing Applications

Target Conductivity for 3DXSTAT ESD PEKK-A:

  • 10^7 to 10^9 ohm surface resistivity on 3DP sample using concentric ring test method.
  • Note: Internal studies have indicated that increased extruder temperatures can achieve higher levels of conductivity. Likewise, lower extruder temperatures have resulted in lower levels of conductivity. Each printer is set-up differently, not to mention varied part geometry. Therefore, expect some trial time to understand how ESD PEKK-A filament works in your specific printer and application.

Surface Conductivity as a Function of Extruder Temperature:

The surface resistance of the printed ESD-safe part will vary depending on the printer’s extruder temperature. For example, if your testing indicates the part is too insulative, then increasing the extruder temperature will result in improved conductivity. Therefore, the surface resistance can be ‘dialed-in’ by adjusting the extruder temperature up or down depending on the reading you receive on your part.

Print Recommendations

Technical Specification

Filament Specifications:
