Makes perfect sense.

How "easy" it is to remove moisture from filament? It seems to absorb moisture much easier or faster than releasing it.

Generally this is moisture in the filament boiling and creating a steam bubble.

I have seen this on PLA. figured its either wrong temp extrusion or just nature of the material. either way I didnt like it under magnification for my irems printed or printer operation issues it can cause

It's been a while I've had this problem.
Filament looks fine when going in, but when it comes out from the extruder, there are these light bumps on it.
It's Solidoodle's filament.

They are 0.42 mm in diameter, so sorry the photos are so blurry.
