Printed models stuck to print bed - how to get them lose

[sebasd]

Hi

Okay many are looking, no one is giving a reply.
Should I remove the top part of the print bed and bend it to remove the model I printed?
I mean the whole black top surface.

Maybe that is easier to understand.

I just installed my wonderful A20 printer yesterday. Took a good while since the description was very bad. Luckily I found a great video by a great person that explanied more and made it happen. But it took 1,5 hour to get it to work anyway.

But now to the real problem.
The model that came with the printer, a bear was printed to about 90% when the filament that came with the printer ran out.
When the model was finished after about 5 hours as long as it was printed, I tried to get it loose from the board. But still impossible 10 hours after and I have tried alot.

Does anyone have any suggestion that makes it easy to get the models you print loose from the board?

Have a great 3d day
