Glass Printer Bed 235x235x3.8mm Borosilicate 3D Printer Print Platforms

I purchased this Borosilicate Glass printer bed for my Ender 3 Pro. The bed is a perfect fit for the print area, and a fantastic upgrade from the stock magnetic build plates. My Ender's bed is not very flat, and I've had to adjust my bed level before every print attempt to compensate. With the glass bed installed, setting and maintaining the bed level is vastly improved. The bed is relatively thick, and it rides above any small imperfections on the underlying heated bed surface. The glass itself is very level, providing a very consistent plane to print onto. The extra weight of the glass I view as a feature, as it seems to help dampen any small vibrations from the printer's use. The bed was thoughtfully shipped and well protected. I'm very happy with the quality of the received product. I can't review the adhesive properties of the bed itself, as I paired it with a PEI sheet. The PEI sheet is absolutely magical when it comes to PLA adhesion. Between the smooth, flat leveling of the glass, and the powerful adhesion of the PEI sheet, my Ender 3's printing experience has been transformed. Prints start without complaint, and stay frozen in place the entire time.

This glass bed has been working great for me for the last several months on my Ender 3 Pro. I clip it to the bed with binder clips to hold it in place and use unscented aquanet hairspray for adhesion and have had minimal issues removing prints. I used calipers to measure the thickness of the glass and physically raised the z-stop switch to make sure I had the right amount of clearance to accommodate it on the bed. It heats up well and appears to distribute the heat evenly. I had some issues at first with warping, but solved the problem with a thicker application of aquanet and a slightly higher bed temp. If using additional products like hairspray, be sure to clean the glass and apply a fresh coat before every print. I have tried to make the hairspray last through more than one print, and it just works better to start with a clean surface. I have been printing with PLA and PETG. I know that printing PETG with a glass bed can be tricky because you run the risk of it fusing with the glass and destroying the print and the glass, but I have used aquanet with every print and only had issues removing one item - it was a large drink coaster with a thick flat bottom and I didn't use enough spray. After it cooled, I was able to remove it with some effort. My longest PETG print was about 22 hours and it popped right off the glass with a gentle tug after it cooled off. Even if I do break the glass at some point, it's been working well enough so far that I wouldn't hesitate to buy this product again. I've had far more success with this than the magnetic build surface that came with my Ender 3 Pro.

There's not a lot to write here. Glass is flat, not warped like the metal beds of most printers, so there are no low or high spots. I have been using this glass plate with the large purple Elmer's glue stick for a couple months. The prints stay attached to the bed and don't warp, and are pretty easy to remove. The glue removes easily with water, and the plate is ready to go again in a minute or two. I tried a few different build surfaces, most worked well for small PLA prints, but larger prints warped and separated from the build surface. I gave up on using build surfaces for PETG, as the prints would bond so well that I destroyed the build surface trying to get the print off. I am happy with the simple glass plate and glue stick. I find that it works very well, is relatively trouble-free and economical.

The glass bed came well packaged in a cardboard box sandwiched between good foam. The glass has nice chamfered edges with no sharp corners and a protective film on both sides. Unfortunately after removing the protective film there was a lot of residue which was difficult to clean off. After using soap and rubbing alcohol it's mostly clean but it's still a bit cloudy in spots. I've printed a few items and all of them adhered well, though I also use stick glue on glass beds. Overall this bed fits my Ender 3 well and is a good surface to print on. Would likely buy again if I want another spare bed.

I question whether this is actually borosilicate glass as it had a green tint on the edges (see photo). My experience tells me that this is in fact not, and is more likely soda ash glass. I cannot tell without potentially destroying the glass, which would be asinine, or having access to a lab, which I don’t have. I am disappointed as I paid more for glass claiming to be borosilicate. In hindsight I should have sourced it from a better place that I trust. I kept them and they do work well. No issues with adhesion whatsoever. Leveling was easy as I used the glass as a shim when I raised the z stop. It’s not bad glass. Should serve most people well. I am generally satisfied, I just don’t think it’s actually borosilicate. Your mileage may vary.

Glass beds are generally great upgrades for 3d printers because they heat evenly and many (like this one) can tolerate high temperatures without warping and because they are very flat. In the case of the Ender series, which is somewhat notorious for having slight depressions in the middle of their surfaces, the latter is important. Glass however can be a little tricky to work with. This stuff is pretty easy however. It seems to hold up well under high temps so far - no problems with expansion or warping yet - and it's an easy surface to work with. What I do is: Get a can of Aquanet hairspray (unscented) Spray the glass thoroughly - I mean, really soak it, then wipe excess Put it on your printer bed, then heat to about 55c or so for 15 minutes to bake it on (you could also let it air dry but that would take an hour or more). When it's dry, do a second coat, then bake it on again. Do this and you'll get a couple months or more out of it before cleaning, depending on how much you print of course. The other thing I recommend is you buy at least two of these, because you need to wait for the glass to cool to room temp. before you try to pop the prints off. Having a second sheet obviously lets you swap between them and keep printing. I've noticed this stuff is fairly forgiving - I've taken off PLA prints after about 5-10 minutes, when the glass was still a little warm, with no problems or ill effects - but YMMV. I print mostly PLA and PETG but have done some ABS as well, the above works fine for all. Really great upgrade for your Ender or any 235-235 printer. I use an Ender 3 Pro and recommend removing the sticky magnetic backing that comes pre-installed for use with the stock magnetic mat. It means the latter won't magnetize, of course, but you can buy replacements and they don't work at temps over 70c anyway so not really suited for anything but PLA.

It's glass. It should always be flat. It's 4mm thick. The original bed on the Ender 3 is less than 2mm thick. So with the springs on the bed all the way down, the nozzle still grinds into the bed. My x-axis is not level on the printer so I cannot tram the bed to be under the nozzle. I will have to find a way to level the x-axis -- if that's even possible. Additionally, the original clips that came with my Ender 3 are too small to be used with this new glass bed and no clips were included with this glass bed. I just got a sheet of glass nearly a quarter inch thick. I ruined my original Ender 3 bed trying to get a print brim off the bed. I had bought this glass replacement when I bought my printer so it's long past the Amazon return window. I wish I had bought the ones like the original bed instead.

A massive improvement over the stock beds on my Ender 3's. The stock beds are "textured" and flexible, which means uneven surface and sometimes extremely hard or impossible to remove adhered prints. These glass beds are perfectly flat and easy to clean and prep while still on the machine. Their adhesion is slightly less than a textured bed but than can be augmented with "Purple Elmers Glue Stick" to increase print stick. Removal is as easy as letting the bed cool to room temp.

梱包もしっかりしていたし、角の面取りもされていたので良い製品だとは思います。 肉眼では反りなども無さそうだし。 しかし、残念ながらAnycubic Cobra2 Neoでは使用できませんでした。 透明なのでZ軸のセンサーが反応せずにノズルをグリグリと押し付けてしまいます。 220度に加熱されたノズルで、ヒートベッドが傾くくらい強く押し付けられてもガラスには傷が付いていないので強度はあると思います。 ヘッドに残っていたプラの食いつきも良かったので、使えないのが本当に残念です。 オートレベリング機能の付いたプリンタでは使えない可能性もあるのでご注意を。 【追記】レベリングのセンサーが金属に反応するらしいので、印刷開始時にセンサーが高さ調節する部分(ガラスプレートの左奥)にアルミホイルを貼ってみたところ印刷できるようになりました。 ガラスプレートだとオートレベリングが使えないので、純正プレートでオートレベリングをした後にガラスプレートを乗せてマニュアルでオフセット調整が必要ですが、ツルツルの印刷面は良い。

I've seen a lot of reviews saying things like 'nothing sticks to it' or 'its a fake creality one' but its a completely different thing to Creality glass and from my experience if: A: Clean it with generic Glass cleaner and a microfibre cloth and, B: Have the correct bed temperature. Overall it works perfectly would definitely recommend it. I use: 55 deg for PLA 60 deg for PLA+ 73 deg for PET-G

As described and delivered on time. Works great on my printer. Would buy again.

Are you wasted a lot of filament and failed Prints before a YouTube video told me I need to wash the bed product worked as intended after.

Perfect for PLA. No issues with bed adhesion.
