Hi,
I want to print a 3D model full of holes inside. However, when I check my model in Ultimaker Cura, it discrete the holes into several slices and create horizontal walls between them. I am sure, that I did not create walls by myself when I create the model. The x-ray does not show the walls anyway.
I think they are some kind of support, however, when I check the support in the software, it is not crossed. Do you have any idea how can I avoid them?
