Official Creality PEI Sheet 235x235mm Flexible Removable Spring Steel Plate Magnetic Sticker Heated Bed Kit Replacement Accessory for Ender 3 S1/Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5 Hot Bed Surface

This drastically improved first layer adhesion on my Ender 3 V2 compared to the stock glass bed. I had tried adding a CR-Touch, replacing the springs, fiddling with temperatures and slicer settings, and using both sides of the stock glass bed, but I could rarely get reliable prints especially for small details on the first layer of many prints. With the PEI plate the filament perfectly forms on the bed from the extruder and doesnt curl or get elephants foot when I use standard 200C extruder and 50C bed temperatures with Overture PLA. Well see how long the adhesive lasts, but so far this is easily the best upgrade Ive made to my printer short of the CR-Touch. Plus you get the added bonus of no longer needing to use the scraper to get (most) things off the bed!

I found this one to be very thin compared to others I have tried. It is a great surface, but would rather a thicker plate.

Purchased this to replace the crappy build plate that comes with the S1 Pro. Just as bad as the stock. Plastic film provides a nice smooth surface and good adhesion at first. The it stops working. If you Z height off you will cut into the build plate which will show up in the following prints.

After a few prints, my PEI coating started to come off. I was unable to remove my prints from the bed even after cooling. Once I was able to remove my prints, the PEI coating came off with it.

I ordered this just to be safe with using an official PEI sheet as opposed to a potential knock-off. The sheet broke on me less than two months in with PLA+ and PETG. I suspect the PETG is what did it in, but I havent had any issues with other PEI sheets like this one. Stuck great but so great that it broke.

It is nice. I think it is well made. I dont think they needed to package it as heavily. Can you get this for cheaper. sure can.

Mine adheres well, well but after heating it to 70C it started to bubble up in some places, enough so that is throws off my mesh bed leveling by almost 1mm because the probe hits one of those spots.

its as good as you can get for a build plate

From the get go, the sheet was nice, the magnetic sheet was great, the spring steel was flexible and the PEI worked very well. After about a week of printing (Mostly ABS at 90c+) I started to see bubbles beneath the PEI and then the corners began to peel up. I tried making a small incision in the large bubble to try to get the air out but negative. More and more bubbles began showing up. I really liked the PEI so I purchased a new sheet from a different vendor, and easily peeled off the now bubbly PEI sheet that came with it. I basically got my money for the spring steel sheet and the magnetic sticker, sadly.
