Borofloat Uncoated Sheet - 1/8" Thick
Ratings & Reviews
Great as a 3D printer bed!
This is the real deal, an actual borosilicate glass plate. Borofloat's data sheet from Schott says this has a surface tolerance of .05 mm which means it is a very flat piece of glass. I placed a flat edge along the surface and couldn't poke a corner of paper anywhere underneath it. The largest square you can get off this plate is ~14.2" (360 mm) and the largest rectangle is ~10" X ~17" (254 mm x 431 mm). You have to buy the whole sheet and I recommend paying for cutting. I've been using it for a couple of months and it still hasn't warped. It saves me so much time and headaches. It is more expensive than other glass 3D print beds but you know this isn't just soft glass labeled as boro, it has tight tolerances, and won't warp. I highly recommend it.
