A missing piece is a discussion on how much problems you'll have if you don't store then properly.
I just have my PLA/ABS/ASA spools on the wall I simply dry then before printing.
I know that the spools can get permanently damaged by moisture... But that seems to take quite a long time as that hasn't happened yet (in my home climate at least).
Its my article and I appreciate your feedback! I will write about this.
It technically can get damaged by moisture but it would have to be years in a very humid environment. Realistically not much can happen.
In my experience, PLA generally is fine in open air. I can't speak to ABS or ASA (haven't used any yet), but I've found that to get the best results from PETG and TPU, I do have to dry it.
I just got a Bambu P1S and dug out some open PLA that was stored in my basement from for a few years and its printing without issue. I feel light exposure is really more of an issue for PLA than moisture.
