Works great and is flat! I heat it up to my desired bedtemp and wait about 10-30 mins so the temperature is everywhere as equal as it could be. I'm printing with PLA and do not need any adhesion! The prints stick like glued to it as long as the bed is not cooling down. When the print is finished and the bed is cooling down you can hear the print slowly coming loose and have a smooth surface. The only downside is the big "Creality" writing which can be seen on the print whenever you print on it.
this is really the magic plate solving all removing problems I had with the original teflon-like platform.
I put the tray on top of the old one and shifted the leveling sensor. I use 4 Maul 19 mm foldback clips to keep it in place and that's it. The best bed temperature for PLA for me is 56°C: a good compromise to stick well to the glass and to easy pull-out the print once the glass cold.
For me the PLA do not stick on it when not heated to at least 40°C.
Arrivé rapidement, parfaitement emballé. Un complément parfait pour une Ender 3, les surface sont planes, le pla et l'abs adhèrent parfaitement. Un produit top.
