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.

Did you recently replace the screen? It looks like there might be light leaking in around the edges, and that you should either replace the FEP because its getting too loose or increase your peel height

The FEP is brand new. I’ll try the peel height.

I bet you printed this huge thing flat in the build plate?

Not the OP, but what do you mean by this? I feel there’s an implication that it should be laid out a different way?

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.

You typically want to angle parts and spam a bunch of supports. Which really is usually the opposite of what you wanna do on an fdm printer.

Ah, I did not pick up on this being a resin printer. Thanks for the info, I’m not too aware on the tech behind resin

With resin printers you don’t want to print flat on the build plate, you want them angled. I’m not the best person to explain this since I’ve only worked with FDM printers but nobody else seems to want to answer lol.

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.

Pretty sure that’s resin though. Also, their issue is likely printing large flat piece flat in the build plate.
Counterintuitive between resin and fdm, but resin didn’t like large flat cross-sections.
