In this paper the long-term ageing effects on FDM (Fused Deposition Modeling) parts manufactured with the material Ultem*9085 are shown after a storage of up to 52 weeks in two different conditions at RT and after the exposure in multiple media relevant for the airplane industry. Furthermore, specimens were tested at different temperatures. After the storage of the FDM specimens at RT in controlled and wet conditionings up to 52 weeks no change of the tensile properties due to different conditioning and time periods is noticeable. Only the elongation at break shows some higher deviations. Furthermore strength properties obtain the highest data for the lower temperatures and are decreasing with rising test temperature. Moreover no change in the geometry after 52 weeks storage at controlled and wet conditionings is noticeable. The weight of these specimens show higher data, also for specimens stored controlled. A reason could be that the moisture content of the material Ultem*9085 is higher after the storage at RT with a relative humidity of 50%. The tensile strength properties after a media exposure show small decreases for most of the tested media. The highest influence on the strength properties of the FDM parts manufactured with Ultem*9085 have the alkaline cleaner with the trade name Rhobaclean and the jet fuel.
