MefineEnder 3 Glass Bed Upgraded 3D Printer Tempered Glass Plate Build Surface for Ender 3/Ender 3 Pro/Ender 3 V2/Ender 5/Ender 5 Pro/Ender 3 S1, 235x235x4mm

This build plate is an absolute game changer. The adhesion is amazing. Once cooled parts separate from the plate with little to no effort. The plate that came with my Ender was terrible and I was always fighting to get things to release. If you are thinking about getting this stop thinking at get it. It is worth its weight in californium.

My first glass bed was horrible, after receiving a replacement for it I am now convinced that there was something wrong with the first bed because the replacement is amazing! The original first arrived and the film on it wouldn't even stick to it fully which was strange. Then I couldn't get PLA to stick for my life but after washing it well I found that the PLA began sticking and then wouldn't release the print FOR ANYTHING. Long after the plate was cooled back down the prints were just welded to it and when I got them removed often plastic was left behind still stuck in a thin later to the glass bed's coating. My replacement however has worked like a dream! Filament sticks with no problems whatsoever, the prints remove from the bed very easily once it has cooled back down to room temp and I can print several prints in the same place between giving it a wipe down without any issue with adhesion. Really the difference is just crazy. So I updated from 2 starts to 5. The first bed I got was 2 stars, but the replacement seems to not suffer from any issues and it is 5 stars for sure!

A glass bed is worth it for sure, but you need to know the following.This bed is not magnetic, so how do you hold it in place? Use bed clips, you want thumb screw clips. put the thumb screw part on the under side. You can lay the glass bed on the bottom half of the prior magnetic bed. Ofcourse you want to remove the top half, the actual bed first. Now where to put those bed clips? when you level your bed that little pressure sensor hangs around and will bump your clips at certain points. Trial and error works well here. Before your bed and bed clips (separate order) arrive go ahead and level your bed once to watch exactly what areas will be out of the way. Once you get the new bed go ahead and install it with the clips, level your bed and make sure there is no hitting of the sensor or nozzle and bed clips. The clips dont have to be super tight just good and firm. If you try using tape instead of clips you will leave residue on the bed and underside, I strongly suggest avoiding tape.Clean the bed with isopropyl alcohol, I use microfiber towels which come in packs, youll want a pack. I tried using finger nail polish remover to clean the bed and that joker made the bed lose its magic, prints are skating all around now. Removing the bed is now more work as you have the clips to undo and redo so be prepared to let the bed cool before removing prints. I use a razor to pry under the print once its cooled some and that helps pop it up.Your z axis has a switch somewhere that it physically touches. Watch a video on how to adjust this z axis switch now that your bed is much taller than before.I have not needed to use glue or cement so far, and I am replacing my bed that I used nail polish remover on. But I do have an enclosure which keeps air temps warmer (36c ish) your larger prints may have corners lifting due to cooling and reheating. A glass bed with an enclosure is a good combo. Bed cement is not compatible with all bed types fyi. The glass bed holds strong at hot temps and lets go very easy after cooling.Glass expands and contracts with temperature change and can bend and sag a little over time so do some more solid research on glass beds. I hope this helps you!

Glass works great, heats up well, and the bottom of prints look much better on this than on the magnetic sheet the Ender 3 Pro came with.I give it a 4 because I have a lot of trouble with smaller prints not sticking. They got knocked aside while printing the first layer or the second. I also have a BL-Touch installed for auto-leveling, and I did Z-offset it correctly, so that's not the issue. I find that a light spray of Aqua-Net hair spray ($2 at the store for the can), works well. Doing a light spray from about 12 -16 inches away (I use a sheet of paper to block the rest of the printer from overspray), works to hold prints, and allows them to relatively come off easy once it cools. I can also reapply more hair spray and do back to back prints. Once you do need to clean, soap and water and a light wash and rinse clean it fine.I'm torn on whether I'd recommend it or not. For me it works well because my metal bed seems to be slightly warped, and the glass fixes that problem. It's good quality and if you're bed is warped, I recommend it. For me, I'll continue using it because I do like the prints on it better. If your bed isn't warped on your printer, it may be worthwhile to stick with the magnetic layers instead.

It was easy to install, it's size was 235 x 235 and the durability is great the glue they use will need replaced after 50 prints or so, the temperature is stable. All you need is soap and water to clean, making it easy to clean.
