PLA stress fractures over time, even just holding it straight like when partially off the roll into the extruder is enough to make it brittle after a few weeks. If you aren't using your PLA for more than a couple days eject it and roll it back into the spool.
That adds up. All the spots it broke are where the filament bends pretty substantially. Thanks.
Ooohhhhh thanks for explaining, that makes perfect sense. I've always wondered why my filament is brittle in the extruder but not on the roll.
Thanks for this. I was worried about how some of my filament was wet in a very dry winter, but this explains why it broke in the spots it broke.
Does this apply to printed parts that are under load as well, then, or are they safer because they don’t get bent/unbent the way filament does (assuming you aren’t trying to do a living hinge or other flexing design)?
