Official Creality K1 Max Matte PEI Build Plate Kit, 315 x 310mm Flexible Spring Steel Platform, Removable 3D Printer Texture PEI Sheet Build Surface for K1 Max/Ender 3 V3 Plus

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.

The bed plate is very good quality. The magnetic adhesive sheet fit well and does not move. Then the flexible steel bed connects magnetically and does not move. I printed ABS on the plate without any glue stick and it did not lift. Good product.

I got this because I was having issues getting prints off my bed with the standard glass bed that comes with the 3 v2 and it has been amazing for that, super easy to take off and then flex to get the parts. Plus I don't have to use glue sticks anymore for bed adhesion which is really nice.One thing if you're having issues with adhesion, clean it with Isopropyl alcohol, it has fixed it every time for meI would recommend using an Auto Bed Leveler with this though since your bed will not be as flat as it was with a glass bed

I like this print bed, it’s easy to install and it works great for the price. It fits the Ender 3 perfectly and takes 5 min to install. The magnetic sheet is very strong and the plate is flexible enough to remove prints without losing durability.The one thing I’ve noticed after 3 months of use is that different brands PLA adhere differently to the PEI. The lower quality of PLA seems to fare worse, and will only adhere at temps of 60C or higher on the textured side, absolutely no chance of sticking to the smooth side. Higher qualities of PLA work great on the textured side and ~60% of the time on the smooth side.Overall, I recommend this plate for a cheap and easy upgrade for your Ender 3. My only caveat is the adhesive quality on the smooth side. Keep in mind that my print settings may interfere with this as well.

This worked wonderfully for the first few weeks, but now prints aren't staying stuck. I have tried cleaning and scrubbing with dawn dish soap, and cleaning with alcohol. Nothing seems to improve it. My z-offset is set properly as well. It just seems to be wearing out.Edit: Comgrow contancted me after my initial review, and provided a replacement. no issues so far5 stars for excellent customer service

I bought this when I accidentally ruined my old build plate using the wrong cleaning solution - which turned out to be a happy accident- I should have wrecked the old plate sooner!!! So this was a replacement for my Ender3 V3 SE. Same exact size as the old plate so no problems at all with fit and so far no adhesion problems with Anycubic standard grey 1.75. I have the build plate set to 65 deg to prevent warping on the first layer - not sure if that's a plastic thing or a plate thing, but other than that it is working awesome. The Ender three already has the magnetic piece so I just set that aside for use later in a carrying tray for wargame minis. If the need arises (hopefully not) I would definitely buy this again and would certainly recommend this product for anyone having build plate adhesion issues. And the price is great too.

This fits perfectly on my Kobra Neo. I had tried a bed which was 220 x 220 but it was smaller than the bed on the printer and I returned it. This one sticks out the tiniest bit (like 2mm) around the edges, but doesn't impede the bed movement at all and it works fine.Great replacement and parts come right off. I didnt need the provided magnetic pad, but it's nice that they include it in case you need to replace yours. I'm saving it if I ever need to replace it or for another 3D printer.

Tried the original plate, glass beds and this is bar none the best plate. Amazing adhesion, completely level and flat (no warpage) doesn't ever show signs of wear, seems like it'll last forever. The magnet pulls the plate to the center so it's easy to realign if you need to take the plate off to get the print removed. Get this plate and be done with it. You'll never look back.

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

Parece la superficie perfecta para imprimir pero no lo es. El producto llegó perfecto, se instaló fácilmente y se veía muy bien, pero al calentarse a solo 50C comienza a "abombarse" cerca de 5 mm de la zona central, lo cual es excesivo Veo dos posibles causas: la zona central se calienta más rápido que las orillas y al tener un coeficiente de expansión alto simplemente se levanta. La segunda hipótesis es que al tener la capa de PEI adherida arriba, con un coeficiente de expansión diferente al del acero, el producto tiende a expandirse a diferente ritmo provocando curvatura. Es simplemente imposible que funcione caliente, su planicidad solo es correcta a la temperatura en la que se ensamblaron/pegaron. Definitivamente es mucho más fiable y barato el simple vidrio.

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've used everything mentioned online and by other people who 3D print to get prints to stick to the bed. Some worked well for a while but reliability with each method declined over time. I purchased this and the adhesion is remarkable! I'm extremely impressed with how well prints stick to this. They stick so well you actually must wait for it to cool down after finished printing to be able to remove the print or you risk warping your part but once the bed is cooled off, the print will just fall right off the bed. It's amazing. I will be putting this on other compatible printers in the future.
