FFF printers that can print PEKK
Polyetherketoneketone for aerospace and space hardware: high strength at temperature with low outgassing. Slower to crystallise than PEEK, which makes it easier to print.
Requirement: nozzle at least 360 °C and an actively heated chamber of 90 °C or more. 1 of 13 indexed printers qualify: Vision Miner 22 IDEX V4.
Qualified
QualifiedThese systems reach the nozzle temperature and hold an active chamber at or above the recommendation, or are closed systems whose vendor sells PEKK.

Marginal
MarginalThese can extrude PEKK but lack the recommended chamber heat. Small parts are often fine; expect warping, delamination or low crystallinity on large ones.
