PEKK-C

PEKK-C
PEKK-C (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK [ 70/30 copolymer] and is one of the highest-performance materials in the world while also being one of the easiest to print ultra-polymers.

Benefits of PEKK-C Include:
    • High thermal properties with a CUT of 260°C (POSSIBLE ONLY POST ANNEALING), 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 resistance

Filament Specifications:
    • 1.75mm +/- 0.05mm in diameter

Recommended Print Settings:

    • Extruder Temps:  345 – 375°C
    • Bed Temps:  125 – 140°C
    • Bed Prep:  Rough Borosilicate Glass with PVP gluestick, or High temp carbon fiber sheet plus PVP glue stick, we also recommend the Vision Miner Nano Polymer
    • Nozzle: We strongly recommend a 0.4mm orifice or larger using one of our Carbide nozzles
    • Drying Instructions:   Please dry @110-120°C for 12-24 hours, for the first dry its recommended to dry for at least 24 hours before using, the drying time can be lowered using a vacuum oven and also storing the filament in a degassing chamber when not in use.
    • Enclosure temp (if your printer is equipped):  70 – 140°C [hotter is better, up to 140°C]
