FFF printers that can print ULTEM 9085 (PEI)
Flame-retardant polyetherimide with aerospace interior certifications (FST). Needs high nozzle and chamber heat to bond layers.
Requirement: nozzle at least 360 °C and an actively heated chamber of 90 °C or more. 2 of 13 indexed printers qualify: Vision Miner 22 IDEX V4 and Markforged FX20.
Qualified
QualifiedThese systems reach the nozzle temperature and hold an active chamber at or above the recommendation, or are closed systems whose vendor sells PEI 9085.

Marginal
MarginalThese can extrude PEI 9085 but lack the recommended chamber heat. Small parts are often fine; expect warping, delamination or low crystallinity on large ones.
