I have printed with old PLA. It is CLEARLY not very good. Even if stored/dried. It also tends to break very easily (even before printing) Archive: https://archive.is/wip/pQNg4 From the post: >>When it comes to knowledge there are things you know as facts because you have experienced them yourself or had them verified by a reputable source, and there are things that you know because they are common knowledge but unverified. The former are facts, such as that a 100mm cube of water contains a litre of the stuff, while the latter are received opinions, such as the belief among Americans that British people have poor dental care. The first is a verifiable fact, while the second is subjective.
