Bad slicing

[HC93 0]

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
