Overview
Polyetherketoneketone — a PAEK family high-performance engineering polymer. Higher amorphous content than PEEK enables lower printing temperatures while retaining near-PEEK mechanical properties. Used in aerospace, medical, and oil & gas applications.

Pros
  • Lower print temp than PEEK (335 vs 400°C)
  • Excellent chemical resistance
  • High strength and stiffness
  • Biocompatible grades available
  • Excellent fatigue resistance
Cons
  • Extremely high print temperature
  • Requires all-metal hotend and industrial printer
  • Very expensive
  • Demands high-temp enclosure (>100°C chamber)
  • Limited brands and colors
  • Difficult to process consistently
Best For
  • Aerospace structural parts|Medical implants|Oil and gas seals|Extreme temperature applications|High-performance prototypes
Avoid For
  • Desktop consumer printers|Budget builds|Any standard printing environment
Storage
Dry storage mandatory — PEKK absorbs moisture rapidly. Dry at 150°C for 4 hours before printing. Store in sealed container with active desiccant.
