Review on ESUN 1.75mm 3D Printer Filament, 2.2lbs - Top Additive Manufacturing Product in Printing Supplies by Deandre Vogt

Yarn has incompatible material properties. I have purchased over 10 rolls of black ABS plastic from Esun and have always noticed small changes in print quality. I kept blaming my printer, thinking something was loose or wrong. Then I started saving the last bit of filament to check between filament changes and of course the pressure between reels with the same model, same bed position, same printer and same cut g-code changed significantly between reels that only two days were delivered. Square test cubes printed using the same file, on the same printer and with black plastic filament, delivered two days apart. The bottom cube is from a roll I've been printing with for the past two days. The top cube from the roll delivered today. I've dealt with bad Esun rolls in the past that accumulated moisture for a few days when I first started using them and have since stored all rolls in a separate container with desiccant. I also print in a closed container with a hygrometer to measure humidity. If it wasn't for the fact that I've spent so much time setting up the printer on a roll only to have to set it up every time it goes through a roll, I'd recommend esun. But the fact that it has such a wide range of print quality is worrying. It's good that I didn't order in large quantities from Esun as planned.
