Mini Delta 3D Printers 120mm Round x 3mm Thick Borosilicate Glass Build Plate Surface for Monoprice Mini Delta

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  ARCTIC Thermal Pad (145 x 145 x 0.5 mm) - Silicone Based Thermal Pad with 6.0W/mK Thermal Conductivity - Flexible and Adaptive  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.

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.

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.

I have a Monoprice Delta mini, so I came into a lot of warping issues with the heat bed naturally.My initial use I actually has to bend my heat bed by hand to make the glass sit flat.This part was due to the bed not the glass; after leveling and using masking tap to secure it to the bed, it produced a very smooth looking first few layers!My delta mini has been a small fight but I will say, for anyone interested in that printer,but this with it. Glass beds are an absolute must!Prints very even and consistently and I don’t need a scraper which is something I greatly liked.I use a cheapo hairspray and it does the job. After I take off the masking tap and wash it by hand.The beveled edged make it nice to handle when cleaning(use rubber gloves regardless)Great product, I never write reviews but I felt this was necessary. Removed a huge headache for me for a low price.

It's a glass bed. There's nothing special about the product itself, it does what it should and does it well. However, I really have to point out how awesome the seller is. After I made the purchase but before it arrived I received an email from Amazon. I'm used to getting these and they tend to be auto-generated messages with thinly-veiled pleas for good reviews. This one, however, wasn't anything like that. Instead it was full of good information and links for people that own the MP Mini Delta. Honestly, I didn't expect that and was pleasantly surprised to find honest, helpful information instead of marketing or other spam.In that vein, here's a bit of info of my own: when printing with this, due to the round nature, your prints may twist a bit. I put down a decent layer of hairspray on the original bed, waited for it to get tacky, and put the glass plate on top. Print some holders from Thingiverse and a razorblade scraper and you are off and running. I just wish I had gotten this from the start, especially at this price.

This fits the printer perfectly. I bought mine to assure I didn't have to deal with any warping of the printers aluminun bed. It would not prevent that from happening, but it doesn't warp itself.Heated bed heat transfer works fine for my needs. It may take a wee bit longer, but it gets me to where I need to be for printing PLA.It is a slick surface, so I advise using a cheap glue stick. It washes off easily. There are no sharp edges on this.You may be able to just buy a cheap piece of glass at the favorite hardware store, cut it to size, and then spend time sanding down the edges to match what you get here. How ever cutting and breaking of a circular edge takes some practice to get right. But you buy this one so you don't have to do that. Trading cash for convenience. Worth it in my book.
