Signstek Borosilicate Glass Plate for MK2 MK3 Heated Bed 3D Printer 213x200x3mm

As the review title states, I bought this for my BIBO Touch 2 3D printer. I emailed BIBO asking if they sold glass plates for their printers here on Amazon, to which the BIBO representative who has been helping me told me that BIBO doesn't, but she told me this Signstek plate would fit, and she's right. This plate isn't precisely the same dimensions as the plate that comes with the BIBO Touch 2. In comparison, this plate is the same length as the BIBO plate, but a bit narrower in width AND in thickness. The difference in width is negligible, it only makes it that much more obvious if you accidentally load the build plate in wrong. However, the smaller thickness means that you will have to re-level your build plate every time you swap between these two glass plates. But again, this doesn't affect me much, since 1. I liberally smear my glass plates with glue stick and 2. I remove my from the printer to let the glass cool down and facilitate print removal. This means I'm constantly re-leveling the build plate in my BIBO anyway. But, I'm aware some potential buyers here may have a solid build plate setup that doesn't require much leveling, so the smaller thickness of this plate may be a deal breaker (at least in regards to BIBO printers in my experience).

Used on a stock ANET A8 3D printer. Works perfect---perfect size, super smooth surface-- no more tape, no more glue! I have two little pinch-type paper clips holding the glass sheet directly on top of my stock bare aluminum heat bed. I'm printing with inexpensive PLA filament and running the heat bed with the attached glass between 59 to 63 degrees C. The actual temperature I set depends on the size of the print. Note: Bigger prints require less heat to stay attached, and benefit from cooler temperatures-- less heat = less distortion to the bottom layers over the period of the print . That being said, I run the majority of my prints at 60 degrees C. PLA print objects hold firm with this glass while the heat bed is held at 60 deg. After printing and letting the bed cool to about 40 degrees C, my prints pop right off with a very light pull or push--- no more scraping or prying required-- it is almost like magic! (Disclaimer: I haven't tried printing with ABS filament.)

Upon arrival I found that one side of the glass was quite wavy when checked with a stainless steel scale. I decided to use it anyway. After a few multi hour prints the plate began to get harder and harder to level. The center of the plate had deformed enough to create a rocking effect that kept one corner always off of the table. Still, worked around it to get prints completed. Last night after starting a short hour long print I went to bed. When I awoke the part was finished successfully and all temps were at room level. The part came free of the glass without any force but brought up with it a near dime sized chunk of glass as well. This is absolute dead center of the glass and makes it basically unusable. Its unfortunate because I really enjoyed some aspects of the glass surface, but not the headache this sub-par piece seemed to bring.

Liking the glass bed way easier than the plastic bed cover on my Tevo Tarantula. I do apply Aqua Net Extra hold because without it will pop off even if I clean the glass with alcohol. I am using Hatchbox so maybe you'll be lucky using something else??? Sometimes I do have to wait for it to totally cool because it is super stuck to the glass. Larger flat surfaced items are more stuck. I apply the hair spray after a few prints and move the prints around to less printed on sides. I clean the plate using dish washing soap and sometimes alcohol or Windex (real Windex). Only complaint is it doesn't cover my entire bed but I knew this based on the measurements given which were pretty close to exact. My glass after about two months appears to be flat still. This will be updated it this changes. I like it better than mirror because of the finished edges and I am only so so at cutting glass.

I bought this glass sheet for use with my Prusa Mendel i2. I have been using it for some time, and thought I was having troubles with my bed leveling.I would make sure each of the 4 corners were at the same height, but my first layer always seemed to lay down unevenly. I was able to compensate, but it was really irritating and blew up quite a few prints! Finally, I checked this glass sheet with an accurate straightedge and discovered that the center of the sheet is bowed up nearly 0.2 millimeters! When I print things with a 0.05mm layer height, that is a huge problem! And if I compensate with the software, on a large print where the center is a good height then the outer edges won't stick and always peel up and curl. Maybe I just got a bad sheet, but I am very hesitant about trying to get another glass sheet for fear I will pay ANOTHER $15 and still have a bowed surface. *EDIT* - I bought an 8" square of borosilicate glass from McMaster-Carr for $30 and it is dead flat in all directions. Makes for an awesome print surface!

Due to aggregation of product reviews, this is for "Signstek 3D Tempered Borosilicate Glass Plate 213x200x3mm" - I use this with my Anet A8, and it is excellent. I found the glass to be quite flat, and does not warp with plate temperatures up to 110C. I started to use it with hairspray, but am now devoted to the PEI on Glass option for any filament. It has been in use now for almost 6 months. Due to a close call with a dropped tool, I bought a second as a backup. Once again, I find this to be quite flat and is very consistent with the first one, and works great with the PEI - the two are very close to the same thickness, so very little adjustment for leveling to switch between them.

Solid plate that fits right on my Wanhao Duplicator i3 V2.1 heated bed. Using just thermal pads, it stays in place and transfers the heat nicely.

I purchased two of these borosilicate glass pieces to use as a printing bed for my Monoprice Maker Select IIIP 3d printer (identical build to the Wanhao Duplicator i3.) The pieces arrived promptly and well packaged with no damage. The size is perfect for my bed - not quite square to allow for the screws that are used for bed leveling. I installed using a silicone thermal pad 400mm x 205mm x 0.5mm Silicone Thermal Pad for CPU GPU Heatsink and installation was quick and easy. The glass was smooth and defect free and well cut. Initially, everything printed perfectly and adhesion, using Aquanet hairspray, was perfect. But within a week of use, I began having bed leveling issues. It took me a while to even consider that the glass might be warped but sure enough, when I place straightedges on the glass, it has warped up in the center. I likely wouldn't have left a 1 star review except that I see from other reviewers that this is a common issue. I would hope that Signstek would reach out to all who have this issue and even more importantly, resolve whatever issue there is in the product itself that causes the warping. Now I'm left trying to decide whether to install the second, unused piece I ordered and risk the same issue (and wasting another piece of silicone thermal bed) or to cut my losses and order from a different supplier. Update: I did decide to install the second glass plate I bought from Signstek. Fortunately, the warped plate was very easy to remove from the silicone pad and I was able to re-use it with the second glass plate. This new plate is flat and un-warped, just as the first one was initially. I will update in a few weeks to report whether or not the second piece also warps. If it doesn't, I will revise my star rating to reflect that not all of the plates from Signstek warp. UPDATE: As of 2/6/2016, the second plate remains flat and unwarped. So that means that only half of the glass I bought from Signstek warped - 1 out of 2. I upped my star rating to 2 stars because the glass is well cut and the edges nicely smoothed and the second piece remains flat. I really hope that Signstek is able to implement better quality control because the reviews indicate that they have a significant number of plates that warped and make them 100% unsuitable for the purpose they are sold for. I really cannot give it higher than 2 stars since 50% of my purchase was defective and Signstek has not reached out to me or most of the customers mentioning this in their reviews (only one that I can tell.) Although I'm very pleased with the Signstek plate that I have currently installed, there is no way to assure that a customer gets a good piece of glass so I couldn't recommend this glass at this time.
