Materials used in space need to not outgas significantly

An answer to this question: Would 3d-printed objects outgas in vacuum?

referred to the NASA outgassing database which showed that ABS, PET, and PLA filaments are all fairly low outgassing and suitable for space application.

What I'm wondering is whether there are any 3D-printable plastics that are both suitable for space and also self-lubricating. Nylon is the obvious printable self-lubricating material, but I believe that it outgasses too much (I don't think NASA has tested nylon filament, at least I can't find it in the database).

My primary interest is in hobbyist-grade, FDM printers but if there are materials that can be commercially 3D printed, that is also of interest.

Any ideas?

I would suggest material from IGUS . https://www.igus.com/wpck/17736/3Dprinting

They have a range of materials that are astonishingly easy to print with on desktop 3D printers also they are probably the world leaders in high load, self lubricating polymer bearings .

I despise printing with PEI (Any type of ULTEM) and PEEK filaments as the upgrades required are a pain to install and keep running for any serious 3D printing related activity .
