The 120mm round 3mm thick round glass plate is designed to work with Monoprice MP select Mini and any small Delta printers that use a 120mm diameter build surface area. Features:A clear, smooth, naturally flat surfaceUltra-low thermal expansion that is resistant to thermal shockSlightly over sized to allow for quick alignment Fits perfectly on Monoprice MP Select Mini and any small Delta printer that uses a 120mm diameterMeasures 120mm Round X 3mm Thick These are fantastic qualities for 3D printing applications!  Package Contents:1 x Borosilicate Glass Print Surface 120mm round X 3mm thick*Important message* From the Manufacture:  Make sure you don’t print PETG directly onto the glass or any other build surface! This will cause your print to stick and you will haft to break the glass to remove it.  Please use hair spray, glue stick or some other release agents when printing PETG. This applies to Glass, PEI, and most build surfaces!

    My prints adhere fine and are easier to remove than with the original Buildtac
  

*by T***A on Reviewed in the United States 🇺🇸 on February 23, 2018*

This round, 120mm piece of borosilicate glass fits perfectly on my MP Delta Mini 3D printer and so far, seems to be perfectly flat. I use extra hold hairspray on the glass and my prints adhere fine and are easier to remove than with the original Buildtac.I used a thermal pad

     that I cut using the glass as a pattern. I did remove the Buildtac first but I don't know if that is completely necessary. I am not using any clips and the thermal pad seems to hold the glass in place - no slipping or lifting.So why use glass? It's a personal preference but I like that the base of my prints have a mirror smooth surface and I also like the ease with which I can remove my prints using a small spatula.I use a glass bed on my other 3D printers and you should know that it is possible for glass to warp. If you start having issues that seem to indicate an unleveled bed, consider glass warpage. You can place a straight edge on the glass and tell easily if the glass has warped. So far, this piece of glass is flat but I know from experience that they can warp later so keep that in mind.

    Great replacement for the standard Monoprice Mini Delta bed.
  

*by J***. on Reviewed in the United States 🇺🇸 on April 25, 2020*

If you own a mini delta from monoprice, this is a nice upgrade for the bed. I use it with a thermal pad to transfer the heat from the aluminum base to the glass and it sticks in place nicely. The standard print surface on my Mini Delta started to tear (Those things don't last forever and you are expected to replace it.) The best way to remove the old print surface is to heat up the print bed to maximum temp 60C, and then slowly work around the edge to peel it up. It helps if you have a thin flexible metal spatula or a painting knife.You can print directly to the glass. If you do I would advise to heat up the bed to increase adhesion with PLA. I would also advise you increase the the "initial layer height" & "initial layer width" so that it extrudes more plastic on the initial layer to grab the glass surface. If you still need some extra adhesion after that, rub a standard glue stick over the surface of the glass, let it dry, then print on top of that.

    Sturdy, solid, and flat
  

*by S***K on Reviewed in the United States 🇺🇸 on April 7, 2019*

For those curious about how to adhere this to the print bed, I recommend a silicone pad for best performance. However, if you have some poster tack handy, it works quite well. I saw that recommended on a forum somewhere a while back, and I have found it works quite well. I don't think the heat transference is as good as the silicone mats are, but if you get it thin enough and cover enough area it works perfectly fine (for PLA at least, haven't tested anything else) and is much easier to find at a local craft store (Elmer's has some called "Removable Adhesive Tack" that I use)In general with this printer, I highly recommend printing out adjustable replacement bed clips for the MPMD before using this and adjusting the clips so that the bed switches engage at the slightest touch. As a quick audio test, whenever I replace or adjust the bed, I adjust the clip so that pressing down on the edge of the build plate, halfway between two of the clips you can hear BOTH leveling switches engage easily (requiring only minimal force). I also press down on the very center and listen for all 3 to engage. I can't stress enough how important I found this, it makes ALL the difference in the auto-leveling to work as good as possible.
