So I decided to do a little experiment. I've read the comments multiple times about leaving prints in IPA too long can cause cracking and also read the article from a resin manufacturer and the test results they got. They did say it varies from resin to resin but I've only ever used Anycubic resin and I've never noticed cracking from soaking in IPA for too long.
I generally try to shoot for 5 to 10 minutes but there's been tons of times I forgotten about it overnight for several hours. Never seen cracking or any negative effects from doing so.
So over the last three days I conducted an experiment of soaking a miniature in IPA for 72 hours straight. I took photos at the 6 hour mark in comparison to one that was only soaking for 5 minutes. Another picture at 24 hours. And final 72 hour mark.
Now to be clear I'm not suggesting or recommending you should soak your parts for 72 hours I'm just sharing my experience and decided to do my own tests using anycubic resin. To confirm my results there is absolutely no cracking from soaking IPA for a few hours let alone three days.
If you would like to make your own test using a different resin and share your results I would be interested to see.
These prints are extras/scraps, so no effort in clean up of supports was taken, they were printed at the exact same time and are more or less the same shape just a different pose. They are regular 28 mm scale printed solid at 0.05 layer height. And the resin colour is a mixture of any cubic orange, skin, aqua blue, clear and transparent green lol
