    The most likely cause of the first two is that the model is not manifold. Inspect it in X-Ray view, and it will probably show you parts in red. The models need to be fixed.


    For the third example, I think the part is just too thin there.

    Yes just checked with X-rays view there is hole inside the object.  and for the third model you are right . walls are too thin .  How can I fix these issues ? can Cura fix these ?


    I have another question : Does anyone know which format of sd card should be used for CR10s pro ? my sd card sometime shows files sometimes doesn't.  I want to reformat sc card . so does not know which format . I use MacBook Pro (Catalina )

    for scanned models `Meshmixer is a good program. There are lots of tutorials to help you. Thin models can easily be checked under 'Analysis' -> Thickness. Set your preferred thickness and it will show all the thin spots. It is also great for repairing.
