    • From Pry Bar to Butter-Smooth Release
Size: 235*235mm Style: One-Sided Textured PEI(Dual Handles）
The PEI Spring Steel Bed is the “mic drop” upgrade my Ender 3 didn’t know it was waiting for. First off, adhesion is flawless. Prints stick like they’ve found their forever home while printing, and then—like magic—pop right off once it cools. No scraping, no swearing, no praying to the 3D print gods. Just clean, reliable results every time. The double-sided texture is awesome: one side leaves a pro-looking textured finish, the other side gives you a smooth base—it’s like having two beds in one. And because it’s magnetic and flexible, I can just lift, flex, and watch my print slide off like butter. 🧈 The spring steel is tough but lightweight, and swapping it on my Ender 3 was as easy as snapping on a magnet (literally). Now my printer feels like it leveled up from “DIY tinkerer” to “pro shop” overnight. In short: sticky when I need it, effortless release after. This PEI bed is the ultimate quality-of-life upgrade for anyone who loves printing but hates prying. If Cinderella was a 3D printer, this would be her glass slipper. ... show more

    • WHAT A MASSIVE QUALITY OF LIFE UPGRADE!
Size: 235*235mm Style: One-Sided Textured PEI
WOW!! I've had my Ender 3 since 2017 and I don't know why I waited so long to do this.. I've been printing on glass and I loved it for the flatness and shiny first layer but sometimes I would have adhesion issues and I also really wanted a textured first layer more often than not for my "utility" prints. Using a razor to scrape my prints off the glass was frustrating and dangerous. I finally bought this PEI and it not only is super easy to get prints to stick well but man is it nice just popping them off the flexible plate when I'm finished! The kit is nice, easy to use, fits perfectly, and sticks well. I put mine right onto my glass to ensure a flat surface, it also helps with heat retention. ... show more

    • Excellend bed upgrade
Size: 235*235mm Style: One-Sided Textured PEI(Dual Handles）
Excellent upgrade for the print bed from the standard Creality bed. First layers of thin walls stick better for less failed starts. PLA pops right off when the bed cools. Highly recommended.

    • Fantastic! Skip the glass bed and buy this instead! Stop reading and buy this!
Size: 235*235mm Style: One-Sided Textured PEI
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! ... show more

Easy install, just make sure you clean the metal bed with isopropyl alcohol or similar before adhering the magnetic sheet. Prints adhere decently and release easily to PEI sheet. There were a few imperfections on the edges of PEI sheet that I received (see photos), but they are outside of print area so not a huge problem. I just wanted to get printing so I didn't exchange. ... show more

    • Solved my adhesion to bed problem on my stock Ender 3 V3 SE
Size: 235*235mm Style: Double-Sided(PEI and PEO）
This was one the cheapest and easiest upgrades for my ender 3 V3 SE. Compared to the original stock sheet, this is amazing. Just a wipe down with 70% rubbing alchohol, and a self leveing any time I change filaments, and all my sticking problems have gone away. If i use a raft when printing, it is almost implossible to remove my print while printing, but after done a few seconds to cool down (PLA) and a twist of the plate and it just pops off with ease. LOVE IT! ... show more

Haven't used the pet side yet but the textured side is doing great with petg @80c bed. Sticks good, pops off easy with no release or adhesion additives. Looks sexy too.

    • Some PLA has a hard time adhering to the bed
Size: 235*235mm Style: One-Sided Textured PEI
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. ... show more
