@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.
