Review on Printer Filament 1 75Mm Dimensional Accuracy Additive Manufacturing Products for 3D Printing Supplies by Marcus Barlow

This string appears to have absorbed moisture at some point during the manufacturing process. How do you know? Well, it was very brittle (breaks easily) and stretched like no tomorrow in all temperature ranges for PLA. That tells me the filament absorbed a lot of moisture at some point, and mind you, that's straight out of the box and in a vacuum bag! I keep it in my dehydrator in hopes of bringing it back to life, but the filament doesn't have to be like this, fresh out of the box. It's a great price but I think you get what you pay for.
