PEI Magnetic Flexible Heated Bed 235x235mm for Ender 3/ Ender 3 Pro/Ender 5

De muy mala calidad, la capa de PEI de levanto a 2 semanas de adquirir el producto, no lo recomiendo.

I have an Ender 3 and i have had so many issues with glass beds. I hated it. There was always an issue with adhesion. First layers would just float up to the nozzle and never get stuck to the bed. I liked the bit of flex of the original bed that came with the ender 3 but that gave a rough surface on my prints and also it would be really hard to take off at times as I would use an small exacto knife to cut off prints. Finally i ordered this and it adheres perfectly. No issues. I never even roughed it up with sandpaper. Just printed it right out of the box. Only issues i have are printer or settings related.Other then that this adheres so well and so smooth. Will never go to glass again. I wasted money buying another glass bed because the other one i had scratched up bad because of adhering issues i had to get the nozzle so close to the bed. Those are the worst. And you need to apply glue for your prints to adhere to glass which i dont want to do.Anyways. Great product. Am sticking to these now.

I bought an Ender 3 Pro, and soon the original magnetic build plate started giving me issues. It was never perfectly flat and level. I bought a fancy borosilicate glass bed and applied a PEI sheet on top of that. This gave me a perfectly flat bed with terrific adhesion, but the problem was sometimes the adhesion was too good and it was difficult to remove parts without marring them or the PEI sheet. In addition, the glass was heavy and limited how fast I could print. And I had to deal with binder clips. I finally got tired of it and started investigating spring steel plates like this one. I read a lot of reviews and could not decide which one to buy. I finally decided on this one because I could get it fairly quickly, and I figured if it was terrible I would return it. I am sure glad I picked this one.Wow. I wish this would have been my very first mod for my printer. I have done a LOT of mods to my printer now, but this is probably going to be at the top of my list for the best ones. The print surface is flat and level, and attaches nicely with the magnet. It is very easy to take the plate off and put it back on. And with a little flex of the plate, prints pop right off. I previously removed the stock magnetic surface from my build plate, so I was glad they included a new one with this plate. It was easy to apply and stuck well.Based on all the previous reviews I read, I was not sure what to expect about this protective film I would have to remove. There was a plastic film stuck over the top that to me, was QUITE clear that it needed to be remove and it was a protective piece of plastic. If anyone can't figure this out, what business do they have owning a 3D printer? Ignore all the other reviews making this sound difficult. It's obvious what needs to be peeled off. Peel it off and move on.After removing the protective film, I started to think there was another layer that needed to be peeled off (all those other reviews were in the back of my head still). But after some careful scraping with a knife in a corner, I decided that was not the case and the only thing left was the PEI itself. The reason I thought maybe more needed to peel off was that there was some damage/pitting on the PEI sheet, but it is all pretty close to the edge and shouldn't really affect printing as I rarely go all the way to the edge.I was going to include some pictures with this review, but that option seems to be gone. Anyways, this is a fantastic build plate and you should buy it!

I had a friend suggest PEI sheets to upgrade my gear, but I really didn't expect it to work THAT much better.My adhesion was pretty tuned in with my stock Ender 3 Pro setup, but these PEI sheets are a slight improvement over that also. Cool.When I come back to get a print after it's completed and the bed has cooled, the print is already loose so I pick it up with no resistence and no residue leftover. It's kinda nutty how well it works.Considering how inexpensive they are, this is easily one of the best value improvements i've made to my printer.

Superior adhesion, if you find an issue with adhesion while using this product make sure that your build plate base is completely flat.
