Creality 3D Official Ender 3 Bed Upgraded, PEI Sheet Removable Magnetic Flexible Heated Bed Plate Build Surface Bed Cover for Ender 3 S1/Ender 3 V2/Ender 3 Pro/Ender 5/Ender 5 Pro 3D Printer 235X235mm

My printer came with a glass plate and I wish I would have bought this sooner! My first layers always go down perfectly now even on small and intricate parts. Large prints now have zero corner warping. I will be buying this again.

Everything just sticks to this bed (without glue). Very easy to remove once cooled. Highly recommended.

Out of all the magnetic plates I have used. This is my fav.

The adhesion on this is unbelievable for PC, PETG, and TPU. PLA is pretty good as well but this surface is great. I damaged mine by thinking it needed as much squish as my textured PEI flex-plate. It pulled dents in the build plate with how well it stuck. Totally my fault and would buy again. Probably will.

First off, I installed it correctly. I made sure my metal plate was clean from oils with 91% iso. alch. -I made sure the magnet was completely flat and gave it plenty of time to cure. a Full 2 days. I placed the steel sheet on the bed and warmed it to 60c for petg. I start printing and withing 10 mins the sheet has warped away from the magnet but also the magnet has warped around the edges and is not sticking to the metal plate at all. I have to clip the sheet and magnet around the edges to get it to work past 60c. It does work wonders when you can get it to not bend. Prints adhear well. Do i need spray adhesive? I was worried the magnetic mat might not stick. It didnt seem very sticky. Have not yet contacted support. debating if this is something i can diy fix/ user error or a real issue with product. Edit- 3/26/23 Nope does not stick, deforms at 60 degrees.

I have ran PEI magnetic sheets for about 6 months and find they are the best adhesion(with alcohol cleaning before every print). The release is fantastic especially for larger prints. So small print still need a little motivation. Downside is the sheets are a lot easier to damage(gouge) then glass. When running firm ware that allows negative z you have to be very careful not to trench the sheet. It does not ruin the sheet just makes it less effective.

Easy to install and wonderful adhesion! Removing a star because after several prints (varying lengths of time and various locations on the bed) there are tiny tiny bubbles showing up in a couple spots. These mostly don’t seem to actually be bubbling above the surface / affecting the smoothness of the bed so that’s good. But it seems weird to be happening so quickly and I’m not sure if it will stay a purely cosmetic issue. If it stays like it is, I’d definitely buy again though. Context: I exclusively print with Inland PLA+ and have the bed about 60C

Gives a nice smooth base surface, adhesion is top tier.

Great product, stick well & released easily from the surface. The best.

Im using a new Creality Ender 3 Max Neo. **No need to apply the magnetic sheet** When I got my PEI sheet I was very apprehensive about applying the magnetic pad, which uses sticky adhesive on its backing to fasten permanently to the heat bed. If it didnt work as intended I would be stuck with a magnetic mat on my machine. It would very difficult to remove it, and clean off the adhesive (if at all possible). So I didnt use the magnetic sheet. I simply removed my glass plate and swapped in the gold spring steel PEI directly onto the heat bed. Its about half the thickness of the glass bed so I shoved a small piece of cardboard under each plate clip and it held snug. Of course, the bed needs to be manually raised a bit first to compensate for the thinner plate. To ensure that the PEI was laid perfectly, I positioned the printhead at all corners and the middle, measuring the distance with a sheet of paper (the paper should slide between the printhead and the plate with just a bit of resistance). Then I auto-leveled the bed. I have so far printed a dozen models, and they all held firm and printed perfectly. The best part... they popped off the PEI sheet with no effort at all. I didnt even need to remove the PEI and bend it. Bonus - not using the magnetic sheet allows the PEI to warm faster because it isnt insulated from the heat bed. And without applying the permanent magnetic sheet, I can easily swap back to the glass bed without the magnetic sheet insulating the heating process. After years of struggling with not enough adhesion, then way too much adhesion - its a dream come true.
