I have mostly been printing with PLA and gotten good results but wanted to try out ABS so I bought a few spools with different colours.
At first the filament is fine, it bends nicely and is hard to break but after a couple of weeks it becomes brittle. It keeps breaking in my extruder.
The same has happened now with three different colours so something is definitely wrong.
Once I start using the spools they are stored all the time (even when printing, filament is fed through a tube to the extruder) in a plastic box with desiccant keeping moisture level at about 24%.
Have anyone encountered this before?
(I keep PLA spools in the same box and they are not showing any kind of degradation symptoms)
Have I gotten a bad batch of ABS or am I doing something wrong?
Here is a video showing how brittle it is. (as you can see the brittleness is not consistent)
