I order 3 kgs of the filament and now matter what settings speeds or temps this stuff would clog my X1C when doing color changes. Now if your only printing this single color its ok just have to get the settings right. I was printing at 250 and about 65 a sec. Printed nice but if you respolled it and or was changing filament you BETTER have a clog remover rod. EVERY Single time. I threw away the other 2kgs I had. Esun or sunlu prints better for the same price or cheaper.
