I'm having a lot of issues leveling my printer and one failed print came out like this. Is there something wrong with the surface that I need a new bed? This happens to me quite often and I literally can't get it off.
If it's flat so you cannot scrape it off you can just print over it. No need for a new bed.
Check your levelling first because if it's sinking into the bed then the nozzle is far too low and you can end up with a scenario where it rips the bed material when you remove a print.
