Storing filament under vacuum
I have a vacuum impregnation setup (deep steel vessel, perspex top with Silicone seal and a vacuum pump with gauges. I bought it for degassing epoxy years ago. I have been using it to dry out my filaments - NylonX and PETG.
It holds vacuum for days once it's pumped down and I tend to forget about it and leave it set up under vacuum with the pump off and the valves closed. Obviously I'm printing with really dry filament when I get around to pulling them out of the chamber to use them. My question is whether either material is likely to suffer from long term degradation by sitting in a vacuum.
