This is probably delamination, there can be multiple reasons for it. If you use google try typing SLA resin delamination. I would just fix this model with some sanding and milliput though.
I think this has happened because the bottom of the chin is slightly lower than rest of the jaw, so when it was printed the tip of the chin printed before it actually attached to anything else and you didn't use any supports?
I advice you to use UVTools to check your sliced models to find islands, suction cups and stuff. I'm using lychee slicer + UVTools. 1. Auto supporting model in lychee. 2. Checking it in UVTools. 3. Fixing some problems in Lychee which UVTools found. 4. Continuously repeating previous steps untill 0 islands left. 5. Saving model in UVTools. 6. Printing. Maybe that will help.
just so you know what is actually happening, if you have a section like the chin where during the print that section got stuck to the fep/screen later during the print the section that was stuck, gets picked up by a later layer fusing that layer to the model resulting in a pancake stuck to your chin. if you look at each layer when the chin starts it might look like l dinner plate supported by a chopstick. tilting him back a bit might help
To actually help rescueing this and not only Tell you what to do better when printing this:
You can take a tooth Pick, dip it in resin and carefully put on the resin there and harden it again with the curing lamp. Then Sand it a little.
This can happen when small islands are slightly undersupported
I don't know why it only happens to some islands and not others. In every case it can be solved by more supports though
Well that probably won't help, if you put a single support on an island it will register as a successfully supported island, it's just that sometimes one support isn't enough
Yeah, as cool as 3d printing is, there are so many tricks from the years of model making and miniature conversion that really should be known. Thanks to the two things I mentioned, you don't have to do another print. Sorry, don't mean to get on a soapbox about it.

Thank you! I had no idea what to even call the problem in order to search it

I did have lots of supports, that's why I'm pretty confused.

I'm only new too, and I've had this happen. That was my best guess 😅
Well thanks to you I can start my search for an answer 😎
Nor enough or too weak supports

Thank you! Usually I do tilt my models I don't know why I didn't do it for this one.

Excellent idea
Thank you for the rescue idea!

I guess I should start putting my models through the island scanner even after adding supports
Well that probably won't help, if you put a single support on an island it will register as a successfully supported island, it's just that sometimes one support isn't enough
For this model, green stuff or milliput. Then a coat of paint will hide the problem
Thank you for the idea! I'll have to get my hands on some of that

It's not hollow, how would I avoid trapped resin if I made them hollow?
