Never use PETG on bare, clean glass. I've peeled glass off the bed (more than once; window glass and the smooth side of Ultrabase) when the part was cooling...loud 'ping!' and there's a divot outta the glass. I didn't even touch the part! I've thought about using PETG to pull glass in a deliberate pattern; antique glass signs and windows used hide-glue ('glass chipping') to peel glass; it looks like ferns or leaves!
i print right on the glass with no glue or anything and it sticks alot to get it off i just hit it with some isopropyl alcohol and it just slides right off hope this helps
Maybe not for modern glass beds. I’ve had a PLA print way too far down and stick too good. I had to hit it hard like a hammer to get it off and the glass is fine. Wouldn’t be something you want to repeat but for accidents it’s ok
no need to use anything on glass, just clean it regulary with dish soap and hot water. PETG sticks like hell to everything but it's easy to remove once bed is cooled down to 50 °C.
You haven’t had it pull pieces of glass out yet have you? The glue is there to help prevent that. It also acts as a soluble layer in case it doesn’t release once it has cooled. But you are correct you can print directly on glass.
I just use hairspray, its exactly the same shit they sell as the spray for 3d printers just 5 times as cheap minimal. and the petg glass issues is due to crappy quality glass simply not usable for printing. like u cannot use every kind of glue in a car engine, due to its heat. not all glass or mirror is usable to print on. but the first consumer printers didnt had annything else then cheap beds due to lack of knowledge or price squeezing. @Bsohh but its not about petg bonding to the glass very well, its about getting it off the bed easely. and the glue particles is between the filament and the bed so thats why it removes easyer.

Love the work🎉
Printing my petg directly on a mirror. Cheap IKEA mirror, no glue no spray no nothing. Sticks well and pops right off like PLA once it cools.

thanks man
So i can print with this filament on a glass bed and to get it off i just need to use isopropyl acohol?
@@zamirroa you don't need isopropyl alcohol but helps a lot
Yeah the glue stick is needed or else you will pull chucks of glass out.

@@bobtheblob2770 PLA will come away fine from the glass bed but PETG will fuse to the glass if there's nothing between the glass and the PETG.
hairspray much easier to clean up and works great just light mist

@@baird1fa Have you tried blue tape? I feel like it would require less re-applying but I'm not sure
@@MustafaSahinz I have yes. But I didn’t have good luck. I found the adhesive of the tape would let go of the bed.
It bonds to glass

I need to try that
Or just go to the dollar store and get a case of them for $5
Or even better than that go to any retail store and get some aqua net hairspray
