Unopened Filament shelf life?

I have an unopened role of ABS I was given some years ago and I doubt it was new then. Posibly 5+ years old.

If I dry it will it still be usable?

Thanks aamcle

Probably fine, if it's been kept covered up. UV light can degrade ABS, but water typically not a problem. It doesn't absorb water much if at all.

It depends what you mean by "unopened", it might be a little dusty. You can get dust wipes as printable parts.

PLA and other filaments do absorb water.

should have a desiccant pack in the package to, so that helps.

The thing with a "best by" date is that it's always a minimum. It is not in Corporate Interest to make them accurate and reduce demand for a product.

Out of UV light, ABS can last for hundreds of years. The GTP is rarely a problem, unless it's been stored over an engine block or somewhere else that's constantly over 100 centigrade.

EDIT: I misread your post. I think I need some new spectacles.
