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. Made using Kepstan® PEKK and Toray® Aerospace-Grade T800 24K Chopped Carbon Fiber. This compound was created for extreme applications where exceptional thermal, mechanical, and chemical resistance properties are required.

CarbonX® CF-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. CarbonX™ 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!

CarbonX™ CF-PEKK product attributes include:

Toray® T800 24K Aerospace-Grade Carbon Fiber
Keptstan® Aerospace-Grade PEKK
PEKK is substantially easier to print than PEEK
Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)
Melt Temp (Tm) of 335°C (allows for lower print temps than PEEK)
Inherent flame resistance (UL94 V-0)
Outstanding mechanical, thermal, and chemical resistance
Continuous Use Temperature (CUT) of 260°C, higher for short durations
Excellent resistance to a broad range of chemicals, such as those used in the oil/gas, automotive, aerospace, industrial, and chemical processing industries

Filament Specifications:

Diameter: 1.75mm (+/- 0.05mm)
Larger reel quantities available upon request

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 - 150°C
Print Speed: 10-50 mm/s for 0.24mm layer height, fast as results dictate
Nozzle Diameter: Minimum of 0.4mm or larger (to avoid nozzle obstructions)
Nozzle Construction: Carbon fiber materials are abrasive and will damage brass nozzles. We recommend a hardened steel nozzle for printing with all CarbonX™ and Glass-Fiber grades. Please see our collection of A2 Hardened Nozzles HERE.
Minimum Layer Height: We recommend layer height of 60% of nozzle diameter for printing our CarbonX™ CF grades. Therefore, for a 0.4mm nozzle, the minimum layer height should be 0.24mm or larger. CF grades exhibit exceptional surface quality and layers below 0.24mm are generally not required to maximize surface appearance.
Extrusion multiplier: start at 1.0 and adjust from there.
First layer height: keep as close to 100% as your printer will allow - CF does not like layers below 0.2mm

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.
