Round Platform Strong Adhesion Circular Hot Bed Tempered Glass Print Surface Diameter 240mm Thickness 3mm for Kossel Delta 3D Printer Hotbed

I purchased this for my daughter for a printer I have given her. I have a Anycubic Kossel printer and now she does also. What I found is that this is a must have for the most 3D printers. It will stick the print to the base ( I use PLA) and will release on cool down. You may still have to pull on them but they do come loose. Most of the time you do not have to use a putty knife to get them off. The base is also very flat as it is made of glass. I used some RTV cement on the corners where the hold downs where and it worked perfectly. Need to have the rough side facing up. Great product and low price. Worked perfectly.

Stays on the build plate for about 5 minutes, if you're lucky. Barely any adhesive, probably to cut costs. Unsticks as soon as you turn on a heated build plate, or leave it alone at room temperature for a little while.It's pretty much a scam. I'd stay away from this and anything else by this seller, to be safe.

So far this is working well. The rough side really dose hold the extruder filament. Heating the glass up to 70 degrees C take a little time but when it cools after the print, the object will just pop off. Keep it clean and wipe it down with alcohol after touching it.

I have an Anycubic Kossel Linear Plus, and this build plate is perfect. Haven't used the smooth side but love the rough side. Great adhesion while being able to easily remove the print, when the plate cools down.Importantly, the primary reason I chose this as opposed to Anycubic's adhesive build sticker (easily ruined, nearly impossible to remove prints!) or their more expensive ultrabase, which appears to be the glass version with the adhesive sticker.Both resulting in needing to replaced, even if they're not ruined by a nearly impossible to remove prints.In any event, I would definitely highly recommend this product.

I purchased this item along with some PEI and 3M adhesive for my Anycubic Kossel Linear Plus. The adhesive was problematic so I ended up not using the PEI, just the glass. I am able to print both PLA and ABS directly on the rough side of the glass. No tape, glue, etc. I heat the bed to 40 C for PLA and 110 C for ABS. Once the print is completed I just wait for the bed temperature to cool down and the item just pops off by hand, no need for a spatula. So far there has been no warping of parts.I use eSun products mostly on the Kossel. PLA+ at 205 C & ABS at 230 C. With the bed temperature set at 110 C my infrared thermometer indicates a glass surface temperature of ~ 106 C at the center and ~103 towards the edges.

First thing to know is that this is tempered glass, not borosilicate. The latter can deal with temperature changes better with less thermal expansion, but tends to be much more expensive. I found this tempered glass bed to work just fine for me, though I always use it with painters tape and don't print on the glass directly. I have done many prints with it and have not had a single problem with the bed.

Sticker does not remain attached. There is a problem with the adhesive. Purchased several and all have the same issue.

Worked amazing on the first few prints. The part would just pop off after it cooled down. After a few prints though parts became more and more difficult to remove. I am about 30 prints in with it and it leaves part of the first layer stuck to the glass. I use the rough side so scraping off what is left is nearly impossible. Also, doesn't seem to be perfectly flat. I have to auto-calibrate the bed if I remove the glass because you can tell one side gets closer to the nozzle. I have turned it 90 degrees and you can see the relation of the nozzle to the glass follow.
