There are so many variations of PLA on the market now.

Every time I go to my local Micro Center I see another variation of PLA. They have the regular one, plus, pro, lite, tough, matte, high speed, and various blends with carbon fiber, and polycarbonate.I've used several so far, and I could see the difference as far as strength, UV resistance, flexibility, temperature resistance, layer adhesion, bed adhesion, etc. Their Website has limited information except for reviews. Here's what I'm getting at. They frequently run out of what I using at the time, and the online system is also out of stock at the same time. This happens while I'm in the middle of a project. Does eSun or another company manufacture their filament? If so, it might be available directly through that manufacturer or on Amazon. Other brands have confusing descriptions such as PLA pro plus with enhanced 5x strength. Does that mean that it's tough PLA, pro or plus PLA?
