I have read that too but my experience has proven otherwise. The pla will only break where it was stretched out straight. If it was a moisture problem it would break much farther down the roll. I leave spools on my printer for days in humid environments and it only ever breaks where it was stretched…

Moisture absorption does not cause the pla to snap off. It is the mechanical stress of being straightened. This is evident in the way that the brittle part of the filament is not the exposed part of the filament but the part that was held straight. If it was mousture absorption the entire exposed po…

Alot of people think that it’s a moisture absorption problem with pla but it’s not. It’s the mechanical stress of being straight after having been curled around the reel. If it was moisture it would continue to break along the air exposed filament but you will find that only the straight part breaks…
