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:

10^6 to 10^7 ohm surface resistivity on 3DP sample using concentric ring test method

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

Annealing (post crystalizing) 3D Printed PEKK Parts: Parts printed with PEKK must be annealed after printing to ramp-up the crystallinity in the resin. This will maximize mechanical, thermal, and chemical resistance properties.

Step 1: Place part in an oven and raise the temperature to 160c, allow to remain at that temperature for 30 minutes.
Step 2: Raise the oven temperature to 200c and allow the part to remain at this temperature for 2 hours. Allow to cool prior to handling part.
