$195.00

3DXSTAT™ ESD-Safe PEKK 3D Filament

PEKK (PolyEtherKetoneKetone) is one of the highest-performance polymers in world.  Developed in partnership with Arkema - a leading supplier of ultra-performance materials. 

Aerospace-Grade Performance.  This compound was created for extreme the most demanding applications where tightly controlled electrical properties, static dissipation, thermal, mechanical, and chemical resistance properties are required.

3DXSTAT™ ESD-PEKK has a wider processing window than PEEK and typically prints with extruder temps between 360-390°C, whereas CF-PEEK often requires extruder temps above 400°C.  3DXSTAT™ ESD-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!

Print PEKK on open-source printer!  You do not need to purchase a Stratasys® Fortus® printer to print PEKK.  This polymer is one of the easier to print ultra-polymers and is suitable for printing using many of the high-performance open-source 3D printers now on the market.  

3DXSTAT™ ESD-PEKK product attributes include

Surface conductivity as a function of extruder temperature:

esd-pekk-resistance.pngThe 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.

Recommended Print Conditions:

  • Extruder Temp:  355 - 385°C 
  • Bed Temp: 120 - 140°C
  • Bed Prep: Ultem™ Tape is the ideal build surface, glue stick on clean glass is suitable
  • Enclosure temp (if your printer is equipped):  70 - 140°C
  • Drying Instructions:  Please see the following instructions for when you want to dry out this filament, HERE.
