Official Creality PEI Sheet 235x235mm Flexible Removable Spring Steel Plate Magnetic Sticker Heated Bed Kit Replacement Accessory for Ender 3 S1/Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5 Hot Bed Surface

its as good as you can get for a build plate

This drastically improved first layer adhesion on my Ender 3 V2 compared to the stock glass bed. I had tried adding a CR-Touch, replacing the springs, fiddling with temperatures and slicer settings, and using both sides of the stock glass bed, but I could rarely get reliable prints especially for small details on the first layer of many prints. With the PEI plate the filament perfectly forms on the bed from the extruder and doesnt curl or get elephants foot when I use standard 200C extruder and 50C bed temperatures with Overture PLA. Well see how long the adhesive lasts, but so far this is easily the best upgrade Ive made to my printer short of the CR-Touch. Plus you get the added bonus of no longer needing to use the scraper to get (most) things off the bed!

It worked good for two prints now it sticks to much an breaks your print

Ive had my Ender3 for about 2 years and have printed miles of filament. I had been using a glass print bed but decided to try the PEI bed. The prints would sometimes not stick to the glass or not come off once completed. This works very nicely, great initial adhesion and the flexibility allows the print to pop off without issue. Additionally you dont need the binder clips to hold the build plate down as the PEI is magnetic which gives you a more complete build surface to use. Love it!

I have no pla sticking issues! Petg I use Magigoo as a pei surface buffer to avoid permanent bonding. I do print Petg at 240c and bed 75c and Creality warns against high temperatures but says it’s good for petg? In any case I print petg! One tip, scuff the pei surface with 000 steel wool if filament starts to not stick. I do that occasionally on another one a year now! Solves sticking issues! Before every print I do a wipe with 91% alcohol to remove hand and finger prints made flexing it. Same on my year old Creality pei surface on another printer.

Bought in June in July the top layer has began bubbling up. Worked great up until then. Definitely wouldn’t spend the premium price for this bed surface again.

After a few prints, my PEI coating started to come off. I was unable to remove my prints from the bed even after cooling. Once I was able to remove my prints, the PEI coating came off with it.

100% happy with this purchase. Great adhesion and flexibility makes it a breeze to remove PLA. Highly recommend

I bought 2 of these for my Ender 3s ... the original flexible rubber mats were in bad shape after hundreds of prints. These spring steel plates are super for popping off prints. PEI coating kind of useless. Bed adhesion was a problem, but a few strokes of Elmers purple glue stick and all was good. Since I already had a magnetic bed, I didnt need the included one. Steel plate sticks firmly to bed, heats up nice, prints have a flat smooth bottom.

a great upgrade for my Ender 3 S1, super smooth surface with good adhesion. 5 stars
