Inner wall is triangulated in Cura


Recommended Posts

Posted · Inner wall is triangulated in Cura



I am strugling to identify the issue here.

My Fusion 360 model looks smooth, however when I import it in Cura, I see the vrtical wall segments.

I have reduced the maximum resolution which has worked in my previous projects but they were small as comared to this one.

From my experience, if you see any defect in cura slicing (preview) mode, it will most definately appear in final print as well.

I have added my test model here. If anyone has come across this before, please share your experience.

    When you create the model file (STL, 3mf, whatever) the resolution settings of the export utility dictates the resolution of the model file.

    The green ring in this image is your model.  You can see how coarse the triangles are.  The red model has a much finer resolution and you can see that the triangles are much smaller.  When Cura slices it is dealing with the triangles and so the facets on your ring would be much larger than the facets on the red model.

    This is a screenshot from MS 3D Builder.  That software has a utility to reduce resolution but it cannot increase resolution.  That's a function of the export utility.
