Yes, I'm familiar with that DB, and yes, nylon outgases too much (though filament, specifically, is not in their DB, other nylon products are).

<p>Materials used in space need to not outgas significantly  </p>

<p>An answer to this question: <a href="https://3dprinting.stackexchange.com/questions/91/would-3d-printed-objects-outgas-in-vacuum?newreg=63cb72665132436c92ff1a842afac664">Would 3d-printed objects outgas in vacuum?</a></p>

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

<p>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). </p>

<p>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.</p>

<p>Any ideas?</p>

The ones I can think of are Polyamide, PET, POM, FEP, Taulman 618 and igus iglidur. Have you already looked into any of these?

Polyamide outgasses.  PET is already on my list, but I don't think it's self-lubricating?  POM doesn't seem to be in the databases.  FEP looks promising as far as outgassing, but is it self-lubricating?  Talulman 618 isn't in the databases, but seems to be a variant of Nylon, which outgasses like crazy.  Iglidur seems to do well with outgassing.  Is it self-lubricating?
