Any one interested in one or more 8" x 8" x 6.5mm Frosted Borosilicate Glass sheet for $50 each?

I have a quote for 20 of these sheets and I only want 3. There is a setup fee so a small run does not make sense. I have been play with glass and hairspray for bed adhesion but the hairspray is not quite enough. I was thinking that frosted glass could make the difference. If you use kapton tape, blue painters tape or other interface materials it should work fine with those as well.

I also wanted the glass to be precise so I can switch from sheet to sheet quickly, the glass I am currently using from Home depot has too much variance (I have to re-adjust the Z axis)

The exact specs are Borosilicate Glass Sheet 8" (+/.01") X 8" (+/.01") X 6.5mm (+/-0.2mm) with both faces frosted.

The Borosilicate will take the rapid heating and cooling needed to do quick plate changes.

Do you know what the dimensional stability is on the z/thickness axis? So far the cheap glass I have found will not make interchangeable plates.

@John_Ridley Thank you for sharing this, in a time I’ll need one bigger than 8" glass and that seems like perfect.

At twice the price of a non-frosted piece of borosilicate glass sheet of the same size from McMaster-Carr (http://www.mcmaster.com/#8476K81), that’s a pretty hard sell.

I love internet communities… The glass shop I found was having issues sourcing the Borosilicate. Let me see what they would charge to frost just one side of the McMaster sheets. (My personal search did not locate the McMaster source… Software Engineers with screwdrivers…

@Blaine_Morgan Hey, I resemble that remark (Software engineer with a screwdriver and a soldering iron).

If they cannot frost the glass from McMaster then I could etch a pattern with the laser cutter at FabLabSD… Does anybody know if that make the glass more susceptible to breakage then a chemical etching process?

Could try glass etching creme from the craft store.

I’m currently using handsanded b.glass with dilluted PVA glue. Works very well.

@Tom_Oyvind_Hogstad Are you printing with PLA or ABS? Is the glue tacky when you start printing? What is your dilution ratio?

I’m printing PLA, but I think it also works for ABS (Read somewhere). I use a dilution ratio of 1:8. It dries almost instantly when applying on hot glass. It is not sticky after drying. I apply some every second print or so.
