Hi, I am new to modeling in Blender but have successfully modeled and printed a few objects. My last model, however, I started to run into problems. It shows as a normal object but when I slice, it's missing the shell. Attached are photos, anyone know what this could be? Attached are photos. Thanks.

It would probably help a lot more if you posted your factory file (File > Save Factory File)

your sliced image is also showing speeds not the different types of layers.

Judging by the fact that it looks like it's generating supports on the inside of your model, I'm going to guess that this model is actually a thin wall shell, which is too thin for the print settings, and is just silently omitted by the software because it's too thin to print.

I suppose there's an error in the STL file, have you checked and repaired the file? https://makeprintable.com/ is a good free tool for this.

Try ticking the Merge all Outlines into a Single Soild Model option on the Advanced tab of the profile.

You'll need to set an infill of say 40% and perimeters and top & bottom layers to at least 3 to get a good structure.
