PEKK-A

PEKK-A
PEKK-A (PolyEtherKetoneKetone) is made using GHARDA GAPEKK and is one of the highest-performance polymers in the plastics business. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK, it’s one of the easiest ultra-polymers to 3D print period. Developed in partnership with GHARDA, a leading supplier of ultra-performance materials.

Benefits of PEKK-A Include:
• High thermal properties with a CUT of 145°C, Tg of 160°C, and a Tm of 305°C
• Substantially easier to 3D print than PEEK
• Wide processing window from 330-360°C
• Inherently flame resistant (UL94 V-0)
• Low smoke generation
• Outstanding mechanical, thermal, and chemical resistances

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

Recommended Print Settings:
• Extruder Temps:  330 – 360°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]
