CR-10 Spring Steel PEI Bed Plate,Heat Resistance, Removable,Flexible,Magnetic Build Surface, with 310mm×310mm,Upgrade Replacemnt Parts for Creality CR-10,CR-10S,Ender 3 MAX

I've tried multiple different beds for my Ender 3; this is the first one that seems to work very well.The stock Ender 3 bed was difficult to use due to needing bed clips, as well as just being a 'meh' bed surface. The Creatality glass bed was nice, but PETG seemed to have adhesion issues. The Ender 3 Pro magnetic bed was convenient, and prints adhered to the bed well, but the bed surface itself would warp on longer prints.This bed sticks right in place of the Ender 3 Pro magnetic bed, and seems to work very well. I use a bltouch with a 5x5 grid, and it was as easy as "remove magnetic bed, drop in PEI spring steel bed, run auto bed level, print". The prints stick well when the bed is hot (7 hour prints run perfectly), and then practically fall right off once it's cooled, making for very easy removal. No more struggling to get the skirt off; once the bed cools, it practically falls off when you turn the bed sideways.Due to being made of spring steel, this bed sticks down very well. That was the biggest problem with the Ender 3 Pro magnetic bed; the backing surface seemed to basically be a massive fridge magnet, and it lacked rigidity; thus the magnetic bed surface itself would warp on longer prints. The spring steel does not warp like the magnetic bed, staying flat, and makes sure that prints come out un-warped.This bed does come with the magnetic underlayment that you will have to install on printers that were not already equipped with a magnetic bed (such as the Ender 3 stock). If you already have a magnetic bed like the Ender 3 Pro, this bed surface seems to be a drop-in replacement.

Perfectly smooth as glass 1st layer! YES!!!!!!!!!!!!!!!!!!!!!Sticks really well when hot.It's A LOT easier to detach finished prints off this golden PEI bed than Creality's official glass bed.(Boy... That Creality glass bed was nearly impossible to get my prints removed. It was a nightmare, the glass bed also left some tiny bumps on the prints.)This golden PEI bed is perfectly smooth. When the print is done, simply remove the bed from the printer and run cold tap water on top of the entire bed and print for a few seconds. Voila - prints come right off with very little effort. Leaving no score marks on the bed.I run it at 60 degrees Celsius and I've seen no bubbling on the surface of this golden PEI coated bed.I've tested 4 different beds and this one is by far *The Best*.Buy it!Thank me later.4 Photos (first printed layers / bottom of the prints):Top left cube of this golden PEI bed B09FPNPL1T (my favorite)Top right cube corrugated golden PEI bed B09P11F12Y (just nasty looking - gross!)Bottom left cube Creality flexible magnetic bed that came with my Ender 3 Pro B07GRSDKS9Bottom right cube Creality glass bed B07DTFG4W2 (My second favorite, almost perfect... But it imprints tiny pattern marks. VEEEEEEERY hard to remove the prints when done, even when it's completely cool).

This is easily in my top 3 upgrades, and saves a ton of time and frustration. Prints pop right off like magic, but if they don't, a slight bend to the plate does the trick.I previously used a glass plate for the smooth bottom finish, but eventually got tried of putting it in the freezer, spraying IPA, and sometimes still having extreme difficulty removing prints. When I got my first PEI plate, the only options were a double sided (rough and smooth) flex plate for around $40, or a single sided rough flex plate for around $20. I wanted the smooth side, so I forked over $40. I wished they made a cheaper, single sided smooth PEI flex plate.After an unfortunate auto bed leveler incident tore up the $40 plate, I went back to the cheapie Creality non-PEI flex plates. They got the job done, but didn't offer the magical properties of PEI.Finally, after being certain the incident wouldn't repeat itself, I was ready to commit to a PEI plate again. To my surprise, there was this new single sided smooth PEI flex plate with only a few reviews. I took the plunge, and couldn't be happier with this purchase.The $20 price point is easier to stomach than $40, and it works just as well. It just doesn't have the rough side, which I didn't use anyway. I now recommend this plate to anyone I know with a 3D printer, there simply isn't a better option in my opinion. You get the smooth finish of glass, the ease of a magnetic flex plate, strong adhesion while hot, and prints practically fall off the plate after cooling. All of this for about $10 more than the cheapest non-PEI plate.

I purchased this for my Ender 3 V2 with some upgrades. From the start, the textured side of the sheet worked phenomenally. I can’t say the same for the smooth side.I every single print on the smooth side fail due to a lack of adhesion, regardless of how much I lowered my Z offset. Also keep in mind that I’m running Klipper with auto bed leveling and I’ve got this machine dialed.I read more reviews and someone suggested washing the smooth side with the rough side of a dish sponge and some soap. After doing this and cleaning/roughing up the bed just a little bit, the prints have been adhering great and I have had no issues.

So far this sheet has been the best. No signs of damage to smooth side after a few dozen prints. Easy to remove prints once the sheet has cooled a little.Only used the textured side a few times so far but all good, flex and prints pop off with ease at anytemperature.

Order arrived and the item was used, possibly a prior returned item from a dishonest buyer who damaged the item and returned.Textured side had left over material and signs of a print, smooth side had been printed on with the nozzle too low, gouging the first layer into the PEI sheet ruining the item, the photos are as the item was removed from packaging.
