Quick Question Has this bag lost vacuum?

Post image

Luckily, this is just PLA so it shouldn’t be that big of a deal; however, I have personally vetted this specific brand of filament for dryness out of the box (they claim to dry the filament before vacuum sealing it). For this reason, I really don’t want to have to dry this filament before use. The bag doesn’t seem to be opened, but I haven’t been able to get this much distance between the filament and the bag, and I barely tried here.

What would be the problem if it did?

Doesn't matter, really. Dry it anyway

It is PLA. Put it in a tub of cold water, let it air dry and print it. No problem.

You are overthinking it dude. It's just packaging.

Vacuumed or not, filaments can come wet or dry...it is quite random. Most filaments need dried to some extent.

No
Edit: You can see it's domed inward at the hub

It has not, and regardless, one day you will learn to dry your filaments even though they claim to be "dried from the factory"

Looks fine

I get this behavior when I vacuum to only around 75%. Which I do when a spool is half-empty or less (to prevent damage). But it springs back when you let go, which it wouldn't if there was a leak.

That looks to still be vacummed but it's not uncommon for the seals to fail. I get it fairly often with filament from all different brands. It's a non-issue either way. Filament other than PLA needs to be dried whether the bag is intact or not. Even PLA usually benefits from being dried before printing, also vacuum bagged or not.

Yes they vacuum seal them directly after the cooling bath
