IMPRESA 2 Pack 3D Printer Glass Print Bed for Ender 3/5 / Pro / 3X - 235 x 235 x 4 mm - 8 Printer Bed Clips Included- Tempered Glass Replacement/Upgrade for Borosilicate Creality Platform-3D Printing

So I used this on my Ender 3 with a magnetic back PEI sheet. It works great and makes it nice and flat. What I did was I clipped it to the bed and then put the magnetic sheet over it catching the clips. Seems to work well. Also it retains the heat way longer then it use too.

The clips included are great. Don't forget they are tucked in the box.I am still new enough that I am likely abusing things and can't tell you how these compare to other glass. I can tell you that with just a layer of CHEAP blue painter's tape, I am getting better adhesion and a flatter bottom surface with PLA and PETG than I had with the factory included surface or the peel off magnetic surface. Having a second matching plate let's me just swap when printing back to back and the tape gets damaged pulling off a print (or removal is looking like it will be a fight). I keep the other plate ready and just swap them out to start printing again, and can deal with the stuck print (and replacing tape as necessary) without stalling the next print, and with the tape layer, I don't see how I could mess up the surface of the glass.

These clips held my glass print bed on my Ender 3 Pro 3D printer great and had a lower profile so the print head didn't clip them the way it did my previous clips.

Item arrived in very good condition, no chips or breakage. The clips that hold the glass to the printer bed could be better, but they will do. Now I can learn to 'master the glass' so to speak.

These are a bargain at $25 for two pieces of flat glass that fit the Ender 3 bed perfectly. I used chemical etching on the surface on one side of the glass to help give it some "tooth" for adhesion. So far it's been working really well. For multiple pieces that require most of the bed surface, I still spray a thin coat of hairspray for piece of mind... considering these are all 8-12 hour prints that have a fine mesh facing. Very difficult prints for a budget machine like the Ender 3 but this glass surface makes it possible. I've been printing PLA at 210° with the bed warmed to 50° and prints stick perfectly. As long as glass cools down, prints pop right off on their own. They key is getting your bed trammed correctly or no amount of glue or hairspray is going to help you. Don't waste your money on overpriced borosilicate glass that chips easily, tempered glass will work just as well, if not better.

I picked up this tempered glass surface for my Ender 3 Pro, and it is awesome. The included clips are very low profile and do not impact my BLTouch or adjust knobs. My first few prints with this were done without adhesive using PLA (190 nozzle / 65 Bed) and they were nice and smooth, the first layer was like glass. This was a day and night difference from the stock Creality magnetic print surface. It helped solve a lot of the un-even bed issues. Even though this is tempered glass not borosilicate, it works great and is about 4mm thick.

I was excited to use these beds when I got them. after a couple prints I noticed that there were issues levelling the bed. Gaps of over half a millimeter in points.After inspecting the glass, I found the plates bulge and thin. If you hold it up to the light, looking down the edge, you can see it's plat on one plane, and warped on the other. This was the case with both plates.I was really upset because I use magnetic sheets to attach my build plates (one on the heated bed, one on the build plate) and it was only after putting the magnets on that I noticed this, so I won't be able to return these. Learn from my blunder, check the plates out, you may get lucky, but you've been warned

I've pretty much always use the glass dead but it was regular glass mirror from local glass shop I was hesitant to get these but glad I did I got some glass etching compound to print crosshair or centering and it worked out great. Highly recommended
