Single-sided Powder Coated PEI Spring Steel Sheet

I was having trouble figuring out why my first layer was having uneven spots, which lead to failed prints, I checked the sheet and realized there was a spot in the middle that pops up when heated, sheet goes back to flat when cooled. This issue started happening two months in and got to a point where sheet is unusable now. Other reviews are stellar, so might be a one off case.

I've tried a few print surfaces now on my ender3 and I think this is my favorite so far. I originally had an issue with the stock magnet having a bubble in it from the factory, so I bought the creality glass bad with the coating, however after a few prints that bed warped and I had to print on the underside with glass only. I ended up having to use gluesticks for surface, but getting prints off was a bit touch at times and I'm pretty impatient. I ended up buying this surface, and so far its been great compared to the glass. I find that since its a bit lighter, my prints are better overall. I noticed my elephants foot that I had on glass has almost dissappeared and prints are now more accurate height wise. I really like the textured look on most my prints and I can usually orient a print if I don't want the textured look. I just ended up buying a PEI sheet from Spool3d to apply to the other side of the surface so I can have dual PEI surfaces on one plate (Textured + Smooth)

So far I am loving this bed. Using 70% alcohol wipe down the filament sticks well. let the bed cool and the print basically pops off buy its self.

had several different surfaces in the past. This is now my go to and works great. I don't have adhesion problems and once it cools objects are easy to remove.

I got this sheet with my cast aluminum heat bed. I've been using Prusa spring steel textured sheets exclusively but I decided to try this sheet out, and I'm glad I did. This thing lays perfectly flat on the print bed, the magnets hold it down firmly, and I'm getting outstanding first layer adhesion with it! With my E3D Hemera on my Ender 5, I'm getting 60mm\s first layer speeds and 100mm\s layer speeds for the rest, all without ANY adhesion issues. Thanks for a great product Spool3D! I'll be ordering more for our other printers.

ABS holds well, and separates easily, but the sheet is not magnetic enough to hold to the heatbed without sliding around on a Prusa MK3S. It will slide if the ABS lifts in the smallest amount and is caught by the nozzle. I'm tempted to drill additional holes in it and turn it around so it can be held in place by the studs on headbed.
