Hi I have the sermoon D3 Pro and the plate is flexible plate, there have 2 side one is A plate and another is B plate. I want to know the difference and what side is supposed to print which material.
Due, I have look up in Creality website, they not even mention about it.

Another question is the plate for D3 is suitable for D3 pro? I have ordered it but it came with 2 different plates PEI plate, PC plate.

Thank you in advance for answering neither of my questions.

Just speaking in general the PC plate sticks a bit too well so much so that it ripped the coating off when I tried to remove a print. PEI is brilliant with PLA/PETG, just let it get cold and the prints all but fall off. PEI does stick rather well to TPU so you might consider glue as a release agent. I’ve just started printing ABS and it seems ok with a PEI plate, minor lifting at corners so I probably should put a brim on it.
