This is the second time this has happened. It looks like it added part of the model on to the side. Is it my slicer? I'm using a Creality Halot Mage, and Chitubox 1.9.5 because that is the only slicer I've gotten to work on Fedora that supports my printer that I've found. I'm completely new to all things 3d printing. This is my first printer and that is my sixth print in the picture.

So... did you?
Contrary to fdm printing, resin printing doesn't like large xy cross-sections because that means huge forces between the part and the fep.
This suction and pulling can lead to delamination of layers.

Sorry, no I didn't. It was printed standing up. I did try printing it flat but that failed for the exact reason you said.

If this is from the model standing up, then I don't really understand the surface marks.
Maybe it was wobbling a bit and would benefit from more supports.
If angle it slightly, which implies spamming a lot of supports closer to the build plate.
Is this a free stl available somewhere?
I don't mind taking some time and trying to figure out how I'd support and print it on my machine.

If that model is one of the flat wallets I'm thinking about, it probably makes a pretty decent amount of suction cups even standing up.
In other models, you can get away with it by adding vent and drain holes, but that may or may not be OK for that model.
Honestly, for the wallet stuff, I'd probably print on an fdm printer more than a resin one.

I see what you are saying. I never thought about that. Unfortunately I don't have an fdm, but I'll keep the suctioning in mind for future prints.
