@matlag My printers are in the basement. During the winter, it’s dry enough. During the summer, it measures at >80% humidity. I’ve got a dehumidifier but can only get it down to around 60%.

In this situation PETG can only sit out for maybe 3 days before it’s noticeably wet.

I’ve still never had a moisture problem with PLA. It tends to simply be an age thing. PLA gets brittle and snaps when under constant pressure, say where it loads into an extruder or AMS.

@Maerman Typically “brand name” filament is going to be more consistent over time and is more likely to have reasonably good filament profiles in the slicer.

Will the cheap stuff also work with some effort, usually. But you might find that a new batch of filament is a noticeably different color. You might find that it absorbs moisture more quickly or is strangely brittle. Or they somehow got a bunch of cardboard dust onto the spools.

IMO if you’re not truly using a ton of filament or trying to make money from this, it’s worth buying the more expensive stuff.
