I like the thermal mass of glass for temperature stability, as I’ve found that’s pretty key to getting good print adhesion. But I really wanted to try out PEI without having to stick a giant magnet directly to my heater plate, something I definitely did not trust.
Turns out, you can solve both problems! This was how I did it.
Oh so there’s sheet PEI which has no metal and can be peeled back off the glass without a fight? Okay. I haven’t seen that, I’ve only seen the metal sheets. (In terms of coated glass sheets, I was thinking about the Ender glass sheet I have with is coated with something, not PEI but whatever they used with my 3V2, and that won’t wear off soon but when it eventually does the glass is done.
Or I guess I could stick these adhesive-backed? PEI sheets that aren’t on metal onto the glass sheet and use it that way.
