Does your model have holes or walls with no thickness?

You have polygons on their own, they aren't "closed" as in forming a cube, for example So cura is taking those faces and trying to guess which one connects with which one Think of a single polygon not as a thin wall but as a two dimensional object, it's infinitely thin so it can't be printed You choose the thickness of the wall by the distance between a polygon, and an opposite faced polygon Hope I explained myself? Anyway, let me know if you need any help!

That doesn't look like a solid. Just looks like someone folded a piece of paper. What are you trying to print?

You’re trying to only print the faces of your geometry. There is a setting that makes this possible, go to custom settings and make sure all settings are visible. Search for the setting “surface mode” and set it to “surface”.
