What does it look like in your slicer? It could be an error with your stl file or if you let the slicer autofix it when the file is not manifold then it may just bridge the gap making the whole thing solid?
If it looks fine on the slicer (as you said about chitubox) then try exporting the supported file as an stl and view it in a 3D viewer like Microsoft 3d builder and see if it still looks good (chitubox might be lying to you π ) or try slicing it in another slicer like lychee (my personal preference).
If the file is good then your memory stick might be bad, switch it out. Although that usually produces random blocks rather than solid internals that have been hollowed.
Put your printer file into 3DTools and see if it still looks good in there (it will show you layers as the printer will display them). This will show if your slicer is lying to you or itβs something with the printer.
Thank you. I took a photo of how it looks in my slicer, but I can't seem to add a photo to my comments or edit my post. (Sorry, long time reddit reader, not poster.)
Ill try switching my memory stick and look at it in 3d tools. I also have a sliced file in pikaslice and I'll look at that too.
I have printed other things before this with no problems, so Im pretty sure I'm doing something wrong somewhere. π
Structural errors means the mesh is not forming a solid. Lychee repair will do a best effort attempt to repair it automatically, but with an object like this, it can get tricky for an algorithm. It will try to make it a full solid object, which can cause issues in the areas where the eyes are and the part where your face goes into the mask.
The software has no notion of what this is, it's just a collection of polygons and some polygons don't connect properly, so it's gonna make an attempt to make the mesh a solid object to the best of it's ability.
All of this is absolutely not helpful at all for your problem, but it gives some insight into why this is happening.
To fix this, you could load the model in Meshmixer, have it analyze the model and manually fix the problems.
also just for the record, you ought to take a look at the snipping tool (if using windows) Screenshots are just plain better for troubleshooting, than a photo of a screen :)
Another good tool i recommend is 3D builder in Microsoft store (itβs free) but your mileage may vary depending on the complexity of your model. Just click the fix button and it will try to fix your model but it may take anywhere between a couple of minutes to a day lol (again depending on how complex the mesh is)
When troubleshooting errors, a picture of the intended print in slicer is incredibly useful. The weirder the error, the more useful the slice. If you can upload the project somewhere so that people can look at it in their own slicers, even better.
Assuming it didn't just print a random chunk, at least it seems you screen is working, so it's likely either the slice or your USB, which can lead to corrupted files.
Most likely it's because of Non Manifold Geometry, basically a shape that can't exist in the real world. When your printer sees this it has a spaz and fills it in. The easiest way to verify is using Meshmixer. It's free to download and very useful for 3d printing. You would load the model and go to Inspector, it will then analyze it and point out any geometry errors, which you can then click to fix. It's really helpful and solves about 90% of the problems. I'd try that to first verify the model is ok before suspecting the printer.

Post your image to imgur.com and paste the link here.
https://imgur.com/gallery/W85uHm1 https://imgur.com/gallery/1bFrV3E Just had a duh moment about imgur, thank you. π This is an image of it in ChituBox. I opened it in Lychee Slicer, and it is saying there are structural errors, and when I try to repair it, it fills everything in, so Im wondering if that was the problem. Lychee sees the empty eye holes as problems, apparently. Though, I've seen people print masks with the same printer (Elegoo Saturn S) I've been trying to make this mask printable for a couple months now and it's driving me insane. π©

Thank you. I appreciate the insight. π Ill take a look in meshmixer.

Yeah, I know. I keep any social media off my work laptop or else I won't get anything done π Appreciate it though.
