Twotrees Double Side Textured and Smooth PEI Bed 235x235mm PEI Sheet for Ender 3 Ender 3 V2 S1 Ender 5 CR20 Genius Mega Pro Aquila C2 S2 X2 Kobra Neptune 2 Shark V2 Odin-5 F3 Magnetic Print Bed Plate

I purchased this PEI print bed a few months ago as I was having more and more issues with the stock glass bed my printer shipped with plus I wasn't happy with the extra weight the glass added. This print bed is very simple to install and only takes a matter of minutes (but you do need to let the glue on the magnetic mat cure before using it - I left it overnight).I've found that I very rarely get a first layer fail since using this print sheet. I tend to print in PLA, PLA+, PETG and TPU and, so far, all work flawlessly. In fact PETG likes to stick a little TOO well but babystepping a couple of notches upwards before starting the print solves this and still gives good adhesion. I also love the choice of a smooth or textured finish as this can make a big difference sometimes to how a final print will look. I did find it helps to babystep a notch or two downwards when printing on the textured side (except with PETG) as this helps give a little more squish.Overall I'm very pleased with this PEI sheet and it has made first layers much more relaxing as I know that, for the vast majority of the time, it'll be just fine. After printing and letting the bed cool to room temperature most prints virtually fall off with no issues at all - at most a little flex of the sheet will free them easily.All in all I really like this print bed even though I do consider it a little on the pricey side. Recommended for peace of mind and the option of a nicely textured (and almost professional) finish for those prints that would benefit from it or the silky smooth (and non glue stained) finish to your standard prints.

If you’ve ever had layer adhesion, print removal, or bottom surface quality issues, this is the surface for you. Prints will adhere easily and release as soon as the bed cools. The flexible magnetic surface makes it quite easy to remove any stubborn prints and the texture doesn’t affect ABL.Be mindful not to print PETG on this, or crash your nozzle into the bed. PETG binds to the PEI and will remove the coating, and a nozzle crash will scratch the surface.

Don't normally leave reviews, but this has saved me so much hassle. After struggling with adhesion issues I've tried multiple build plates. Glass, polycarbonate glass, magnetic flex bed etc. Both types of glass ended up in the bin after trying different things to get them to work. The magnetic flex bed worked well, but is easily damaged removing the prints.This PEI bed has easy perfect adhesion on both textured and smooth sides (basically two build plates for the price of one). Easy to remove prints and hassle free. If both surfaces were ever damaged, I would definitely get another.

The textured side is great, fantastic grip, good self reelease and leaves a very nice effect on the underside of prints.The smooth side however is awful, the pei is very soft meaning it's damaged by even relatively blunt objects if you happen to wave them anywhere nearby. The nozzle left a mark on the bed while heating above it, not touching it, but sitting at first layer distance (also the nozzle only went to 205°C which should be below glass transition of PEI). I accidentally caught the surface with my nail and it ripped a huge gouge out of it. I have a different PEI sheet from another manufacturer that is like diamond by a hardness comparison (and has had heavy use for 2 months and is still adhering incredibly well to this day) No gouges by accidentally catching it with a nail.Tldr: If you want a textured bed that side is great, if you want smooth seriously don't buy thisEDIT: After talking to seller they very kindly sent me a double sided magnetic PET sheet to make up for my bad experience with the smooth PEI side and I have to say it's quickly become my favourite print surface. Basically flawless, needs minimal cleaning and leaves a very pleasing carbon fibre look on the base of the print, Upped review to 4 stars to reflect

Exceptional build quality and customer service. I had a slight issue with the first one of these I received. A very minor defect along one edge that didn't affect it's ability to be used. The seller reached out and sent me a new one immediately. Cant fault the customer service. And the bed itself is incredible. Hold firm when heated and releases immediately once it begins to cool. Also double sided. Perfect upgrade for my ender s1 and fits directly on the original bed base. Just remember to change your Z offset as this one is slightly thicker than the original one.

Was finding the included print surface of my printer frustrating with variable results for no reason.Bought this Two Trees pei sheet and had no issues at all since using it.First layer sticks well with no need for glue stick or any other treatment.When bed has cooled the part either comes off very easily or is just sat there already released due to the bed cooling.Used it with PLA, PETG, ASA & TPU.I liked it so much that when I got another printer the first thing I bought was another two trees PEI print sheet for that printer too.
