PEI plate poor quality?

Hello, I have read in another forum that the PEI plate of the A1 is of poor quality and that the prints do not stick well to it…
Has someone uncountered the problem ?

Nope, everything I printed has been fine. So far just PLA & PETG.


I had the same issues with some PETGs. I use the Bambu liquid glue, which works flawlessly. If the problem also happens with PLA, I suggest cleaning it with soap, warm water, or IPA. I also use the Textured PEI plate on the X1(the same plate, just bigger) to print nylon, and I have no issues using it together with PVP glue.
The Smooth PEI plate works equally well.

I’m having the same issue. It’s hit or miss if it sticks or not. Sunlu PETG sticks ok, but I’m struggling to get BBL basic PETG to stick; and my overhangs suck with the default profile. I’ve tried with and without the liquid stick.

WIth textured build plate:
No issues with PLA.

Had adhesion issues with PETG, but they stopped after I cleaned the build plate with IPA.

I have no Problems with PLA (Sunlu, Overture, eSun, deleyCON, AMOLEN) and PETG (Prusament). Everything absolut fine and as good as my old Prusa Mini+

No problem on eSun, Siddament and some non-brand eBay PETG on PEI plate.
Bed temp at 70, hot end around 240-255, wash the bed with warm water and soap if bed not stick.
