Slicing in Cura - grayed out internal layers

[naomi_dahmer 0]

Hello everyone, 

It's probably something easy, but I tried with every setup with no effect. I'm not pro in 3d printing, just started to learn things during quarantine time :)

After slicing mask mold model from https://www.thingiverse.com/thing:4280996 CURA shows only few bottom layers and few top layers. I can't slice it and print it properly. Is this problem with model file or am I doing something wrong in CURA?

Likely an issue with the mesh itself. If it's not manifold it wont slice well. Try using the meshtools plugin in the marketplace, this will fix any holes in the mesh.

this will let you try to fix holes in the mesh.

Thanks Guys, unfortunately result is still the same.

Like I hinted at, there are models that MeshTools will not be able to repair. Your model is likely still broken. You will have to "repair" it before it can be printed.

I've had a look at the model. The model is actually not broken, but its walls are too thin. You will likely have more success of you slice the other model (part-fcszbs-2.stl) with "Infill Density" set to 0 and "Initial Bottom Layers" set to 0.

Thanks for help.

This whole model is mold, which I'm going to use with recycled cardboard to make cardboard masks.

I've already printed successfully part-fcszbs-2.stl - that is solid part of mold. Only problem is with hollow part of it. 

Since I'm not good in 3d sculpting from the scratch I think I'll contact original maker of this mold via thingiverse.
