I have been printing with PETG on glass for a little while now, and have gone through almost an entire roll. Yesterday I had my first print stick so hard that it delaminated the glass :(. I stopped using hairspray as it made the prints not stick at all, and printing bare glass was just fine. But something about yesterdays print made the glass give up. Is this how PETG + Glass normally fails? Works perfectly for years, and then suddenly fails?
I went with glass originally as it seemed at the time to be durable and therefore less waste. I don’t want to generate extra waste. And those pei sheets dont look cheap :/
Thanks for the suggestion though, will keep it in mind
