Good evening,

 

I'm modeling a kind of hollow cube with Blender in order to print it (first image).

When Cura slices it (just after import, with basic settings), the top is filled (second image).

When I rotate the cube of 45 degrees, the model is sliced "correctly"(third image), but I don't want print it in this position.

 

Do someone knows what go wrong?

 

Thanks you,

Regards,

Hugo

    Most probably there are errors in the model. The x-ray-view in Cura highlights errors that are found.

    "Mesh tools" can do some simple repairs (right mouse click on the model).

     

    Some things to check in Blender:

     

    Is the model manifold?

    Check for doubled or missing faces, and check for non connected or overlapping vertices. Always do a "merge by distance" in edit mode before exporting, just to be sure.

    Check the normals - are all facing in the right direction? 'Face orientation' can be enabled in the viewport overlay.

     

    Good luck!

    Problem solved, thank you very much!

     

    In my case, I had no overlapping vertices, but some of the faces had bad orientations.

    I modified it on the Blender model and now it's good.

     

    All my best,

    Hugo
