I’m new to bambu - I have an A1 and P1S coming. I’ve been printing for almost a year on another printer - rhymes with ankermake.
Anyway, I see that the bambu filament comparison page says for PLA “no drying”.
I also see that both PETG and PLA says “do not seal with desiccant”
Guess who has been sealing their PLA+ and PETG with desiccant in vacuum sealed bags. 
Anyway - what are the most recent recommendations on these 2 topics?
‘No drying’ - just means no drying required. It can still be beneficial if you happen to get some wet filament.
I’m not sure where that ‘do not seal with desiccant’ comes from or the context but it is standard practice to place dried filament rolls in a sealed bag/container with / without desiccant. In fact all the bambu filament I have ordered came in a vacuum sealed bag with desiccant inside.
Im not going to post them all
one is pla basic the other petg-hf, check in your regional store
Welcome to the forum! I guess they meant not required… but I definitely do. Also it’s going to come sealed with desiccant and when you put it in the AMS it’s going to be sealed (almost) with desiccant. Keep doing what you’re doing, it’s just fine.
About the do not seal with desiccant, I don’t understand why they would say that. If (big if) the desiccant is sufficiently dry, it won’t give up water to the filament.
I suspect many leave their desiccant sitting out (where it will grab water from the air and equilibrate with the ambient humidity) and toss those packets in with filament. That is bad because the desiccant isn’t dry and can give up or absorb water depending on what it gets put in with. Packets left sitting out look just the same as those kept dry (unless there is indicating desiccant).
Filament can arrive with significant moisture even packed in vacuum bags with desiccant. I have also found desiccant packs packed with every spool of Bambu filament so they violate their own rule. But fresh PLA can be ok or not ok in my experience for moisture content. It used to be generally ok and drying wasn’t even a thing I had to do but my PLA started printing poorly occasionally and then consistently as our humidity climbed into last spring/summer. That was also about when Bambu started shipping problematic white and black so weather or supplier I can’t say. What I can say is drying fixed it up.
Thanks! Glad to be here.
I do like sealing up the spools in vacuum sealed bags. I guess it’s an ASMR thing 
good info - many thanks - I do like sealing them up
Lol, same here. Trying to walk that fine line between getting every single molecule of air out but not so much you crush the spool.
They mean you don’t have to, not that you shouldn’t.
Their filament is SHIPPED sealed with desicant
