The PAEK family

PolyArylEtherKetone (PAEK) is a family of semi-crystalline high performance thermoplastics that are characterized by high mechanical strength and excellent resistance to temperature, chemicals and wear.
The most widely used members of the PAEK thermoplastic family are:

  • PolyEtherEtherKetone (PEEK)
  • PolyEtherKetoneKetone (PEKK)
  • PolyEtherKetone (PEK)
  • PolyEtherKetoneEtherKetoneKetone (PEKEKK)
  • PolyEtherEtherKetoneKetone (PEEKK)


General printing guidelines *

Nozzle size: ≥ 0.4mm Layer height: ≥ 0.10mm Experience level: Expert
Print temp: ± 400 – 450° C Fan speed: 0 – 25% Drying: +4 hours at max.110°C
Heat bed: ≥ 120° C Enclosure needed: 90°C heated chamber Adhesion: EasyFix Nr. VII

*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these parameters if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends and printer offset that it is extremely difficult to give an overall one-size-fits-all setting.


Please be aware that LUVOCOM 3F PEEK CF 9676 BK filaments contain a relatively high concentration of extremely hard carbon fibres, which have an abrasive nature. In general these carbon fibres will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. We recommend to use nozzles from stainless steel or other hardened alloys.
