Bubbling / warped sprung steel sheet
I've done a few calibration prints up until today and even printed a prototype of something I've been eager to get "production ready" to ensure my measurements were all ok. Everything checks out so I printed my first proper part. Print took 2 hours to complete, then I left it to cooldown and popped it off the sheet as the instructions say to.
Now the steel sheet has a little bubble which looks like it goes around the perimeter of the square shape I printed.
The part was printed on a standard PETG profile with prusament PETG jet black. Can't imagine anything I could have done here would have been the cause.
Is this a faulty sheet or has something else happened?

PETG sticks very (too) well on PEI sheet, you need some kind of release agent before you start to print.
I use glue when I print PETG or ABS on PEI sheet, I know others use other things

Thanks for the reply. So much to learn with this new hobby. Slightly frustrated with myself that I didn't pick up on the info that's clearly out there about PETG.
Not the cheapest mistake to make but it is done now....
