Filament now brittle :(

Actually, is the filament in sunlight ?

Abs is subject to uv breakdown. It's one reason outdoor things are often better made from pla, which isn't as susceptible to uv radiation.

Makes more sense than water.

No, its actually in a dark room. Plus I live in Utah, which has a pretty low level of humidity. Maybe I did get a bad roll or quality, not sure. I had a few people who've printed with it recommend them. I have been pretty much using Octave brand, but I thought I'd try others, especially since its a little cheaper; but cheaper isn't always better.

weird.

You don't by chance have one of those room 'freshener' sprays in the room ?

Just a thought, that crap could rot through anything.

Lol...no. I'm wondering if I should contact E-Sun and ask what they can do (which is probably nothing).

I have had perfectly good brand new rolls that are brittle in places. If you tested the filaments raw brittleness, most place it will just bend, but every few inches or more it would snap. It hasn't affected print quality at all from what I have seen. I am more concerned with layer adhesion which directly affects part strength.

I got thinking about that earlier, and took a look under a scope (thanks for the idea Geoff). I could tell after printing and cooling, there were a few micro lines of space. Who knows if its the brittleness or the machine.
