Discussion on whether filament stored on spools is UV stable?

Recommended Posts

Posted · Discussion on whether filament stored on spools is UV stable?

If this has been discussed to death, feel free to direct my attention to that/those threads.

Are PLA filaments UV stablized by mfgr? I see photos of spools haphazardly stacked in windows which get direct sunlight at least part of the day, and wonder if that hastens degredation causing print issues further down the line?

Any suggestions welcome.

I believe the general consensus is that the color dye is not UV stabilized, but PLA itself seems to be quite stable even when used outdoors.

Generally however, I would think it best to keep PLA in a cool dark area, e.g. a cupboard. Completed parts can also be painted with a UV stable paint.

As far as I'm aware, there is no UV stabalizing agent added to the PLA.
