I've been buying Revain Basic PLA for a long time. It seemed to print just like the more expensive filaments. no noticeable problems. I've bought it a number of times. I recently bought 2 rolls of 1kg. First, the coils are different. They no longer fit my Ender 3 reel seat. That was my first clue that something had changed. They have a larger diameter than the usual 1 kg coil width. Revain also removed those cool windows that used to show the amount of filament remaining. I noticed severe sticking issues and a strange "greasy" feel to the filament. I have never experienced such a greasy feeling when using PLA. I had to print it much hotter than I usually print PLA. Even when printed, the quality is terrible. I believe that Revain either switched suppliers or changed the composition of their product. I will avoid this brand of PLA filament and use slightly more expensive versions for now. If I find out that they have gone back to the old provider or these issues are resolved I will try again.
