Which filaments shed the least dust in use?

[JohnInOttawa 104]

I'm considering 3d printing some lids for jars.  The lids don't have to be airtight or watertight, will really just hold cloth in suspension to keep dust out of a solution that needs air but not dust exposure for a period of time.

 

My issue is with the 3dprinted part itself.   I have seen some filaments deteriorate over time and leave dust.  I'd like the lid to shed as little dust as possible.    I'l thinking something like T-Glase might work, but honestly, that's just a guess. 

 

What's the best option here?

 

Thanks in advance!

Are you able to spray the parts with a clear coat as that would seal the 3d printed part, but maybe over time the coating would wear off with open/close action of the lids.

 

Maybe 3d printing the lid and then making a mold from it so you could make the real ones from the molds with food safe resins?

Thanks!  I did consider coating but have experience with coatings flaking off as they degrade. 

 

The molding route would work, but I'm not set up to do that.  My fall back option will be to extend the cloth far enough that no part of the lid can shed into the jar's interior.  I'll just have to back off the threads enough to make room for the cloth.

 

Thanks again!

I would give PP a try.
