I’ve had an Ender 3 for some time, around 2005, and I bought a lot of filament. Three of them are still here. One each of Black, White and Wood PLA.
I’ve a new system and added the old filament to my available stock.. All were stored with silica and all show 10% on the humidity meter The Wood worked fine but the Black and White are very fragile. They break off in the Bowen tubes very easily. It isn’t much of a problem as I can keep reinserting it and it keeps restarting fine.
What is the expected lifespan of filament? Would it help if I left them out to actually get a bit more moisture in them until they get into the 20s at least? Any suggestions on the best way to use them.
