Cura Doesn't Slicing Properly


Recommended Posts

Posted · Cura Doesn't Slicing Properly

Hello there,

I want to print that buddha statue for my aquarium; but when I slice the .stl file it doesn't slice properly. Some layers flattening suddenly; but the model seems fine.

What can I do to fix this issue?

    That is because the model is invalid. The highlighted areas with the polka dots indicate that. You should have also received a message indicating that the model isn't correct.


    There are various tutorials / fixing algorithms to fix non-manifold / non-watertight meshes. Try one of those and see if the problem is still there. Alternatively, try to find another 3D model that doesn't have these issues.
