How long can you safely leave prints on the build platform?

Does any one know how long you can safely leave prints on the build platform without resin starting to harden on the parts or the platform. So far, I have been removing the prints within 30 minutes of their completion. I want to print at night, leave the office, and remove them in the morning, but I wanted to make sure that I’m not asking for problems with the models or the platform. Any advice?

As long as you like. See post:

That’s great! Thank you!

Just to echo my thread, its true I have left a part sitting there on whole 8 hr day and came back it with not problems.
