HELP Ultimaker Cura Software Prepare - Preview

[OlgaBurg 0]

Hello

 

I just started using the Cura slicing software and imported a .stl object. 

In the prepare window the object looks as intended (needs to be hollow on the inside, see picture one)

However when I do a preview of the sliced object it is completely filled out. (see picture two)

What do I have to change?

Kind regards
Olga

Your model is likely "non manifold". Read this article:

https://github.com/Ghostkeeper/SettingsGuide/blob/master/resources/articles/troubleshooting/missing_parts.md#non-manifold-meshes

 

The model (also?) has an issue where the normals are not consistent. Some are pointing outwards, some are pointing inwards. Your model needs to be repaired.

Recalculating Normals did the trick. Thank you for the tip.
