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 has been a game changer for me. I fought with too much adhesion to a PEI glass sheet. I would commonly break prints trying to remove them. Just lift the front of this and everything pops off of this. No complaints whatsoever. I have not had any issues with prints staying adhered yet either.

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.

This bed is so much better for my S1 printer than the bed it came with. The prints sticks really well but pops of easily. The only problem I have is you have to lay the bed past the screws at the back of the printer bed or else it wont fit.

It works so well with PETG

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.

It worked for me, and that’s saying something, because I’ve been through three different beds on my Ender 3 v2. The bed is very sturdy yet is easy to flex, and the thick magnet sticker is easy to put on without leaving bubbles. Most of all, the adhesion is amazing on this thing. However, different things will work for different people depending on where they live, the climate there, their home, etc. This was just the solution for me. The only bad thing is that prints can sometimes leave marks on it.

I love the smooth texture on the bottom of my prints. This removable flexible plate is great and I have printed hundreds of hours on it without any issues. I have used cheaper knock offs with very thin PEI that have failed after one or two prints. Quality here seems to be much better.

A chunk of PEI came off with the print after only a week of light use

Im using this on my ender 3 pro and I love it. I had struggled with adhesion on just about every other bed surface. On glass beds I had trouble getting the print to come off. On the flexible magnetic beds I couldnt get it to stick in all places. I also tried a PEI covered glass bed and I couldnt get anything to stick to it. This spring steel is literally the best of every type. Its smooth like glass so your first layer is super smooth. Everything adheres without issue. When its time to remove the print just a light bend and it pops right off. Its also magnetic so you dont need clamps to hold it on. I will only use this bed from now on. I cant recommend it enough.

Absolutely love the magnetic print bed. So much better then using binder clips that my printer came with.
