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

Have been looking at these for some time and couldnt pass on the price.

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.

Ive had my Ender3 for about 2 years and have printed miles of filament. I had been using a glass print bed but decided to try the PEI bed. The prints would sometimes not stick to the glass or not come off once completed. This works very nicely, great initial adhesion and the flexibility allows the print to pop off without issue. Additionally you dont need the binder clips to hold the build plate down as the PEI is magnetic which gives you a more complete build surface to use. Love it!

Clean prints great adhesion. Love the pop. I rarely have to use a tool but on super small prints I found plastic razor blades upside down are amazing and do not damage the PEI

After only having this bed for 2 weeks the top film is starting peel off from the bed.

Maybe hard to see in the pics but small air bubbles are starting under the sheet. They are getting worse after every heat cycle of the bed. We’ll see how long it holds up…

I originally thought that this product wasnt what I was looking for. I was having my prints slide off the PEI sheet in mid print, nothing would stick. I tried glue, hair spray , tape etc. Well if I had bothered to look a little closer, I would have known to scuff the sheet with a scotch brite lightly. After the scuff, this PEI sheet is fantastic, so good I bought a 2nd one.

First off, this isnt my first time using PEI beds/sheets. I have another one thats from Gizmo Dorks and has worked great but needs to be resurfaced. Since I was feeling lazy I thought I would give a Creality brand PEI bed a shot. Packaging was good and had no damage when I got it. I removed the protective film on top of it and cleaned thoroughly with iso. I have noticed that this bed seems to have a dull/matte finish instead of the usual glossy finish that Im used to... Now Im wondering if this is whats causing my trouble. The standard filament configurations that would normally give me great bed adhesion couldnt keep on the bed no matter what. My next step will be to try and gloss it up. If this works though, Ill be annoyed that I had to put in the extra work.

I bought 2 of these for my Ender 3s ... the original flexible rubber mats were in bad shape after hundreds of prints. These spring steel plates are super for popping off prints. PEI coating kind of useless. Bed adhesion was a problem, but a few strokes of Elmers purple glue stick and all was good. Since I already had a magnetic bed, I didnt need the included one. Steel plate sticks firmly to bed, heats up nice, prints have a flat smooth bottom.

Ok, if you have the original plastic bed that came with your printer I feel sorry for you. If your tired of dealing with stuck prints and just horrid performance with the bed then look no further. This plate is the best thing I ever bought. Sticks good, but releases instantly, no fighting or cleanup issues. Comes clean the first time and every time.
