Posted · Very simple shield model has erronous areas in Cura

I am trying to print a small shield (attaching it to a d&d miniature), but cura X-ray shows some erronous areas  and the printing fails as well.

 

Here's what it looks like:

Anyone have an idea on why this simple shield cannot be printed?

    Your model is probably not watertight and therefore the slicing fails and Cura shows you the red areas.

     

    Have you designed the model yourself and if yes, with which software?

    Looks water tight to me, if you mean holes.  

    I pulled it off a different character using Blender. I didn't model the shield myself

     

    Even then it seems a bit ridiculous to mark the entire 2 sides red if there is just a hole somewhere?

    Could also be a problem or failure during the export to the STL file and not water tight doesn't mean you always see the problem. A single polygon which is missing could be enough.

     

    Try to repair the STL file here:

    I managed to fix it in Blender (there were no holes).  The 2 sides of the shield were isolated planes,  which isnt allowed for some reason.

     

    I connected those 2 circles into a cylinder and now it prints fine

     

     

    In fact from the pictures you could've easily guessed this instead of 'check for holes' 🙂

    The reason is that the mesh needs to clearly delineate what is inside vs outside the solid. Isolated planes do not define a solid.

     

    If you are interested in more details, you can google “boundary representation” or “BREP”.

     

    glad you were able to fix it.
