Thank you for all the replies! It was my stl file problem. The normals of inside bubbles are random, but not point to inside. I wrote a script to check this kind of thing and it is solved. Thank you for your advices.

I think I did not set units in MATLAB (actually I do not know how to do it). I set a unit 1 for the cube. I think we can modify the unit inside Cura.

Thank you very much for your suggestion and website. It works, however, deletes all my precious-voids. I will try to solve the output problem in MATLAB tomorrow morning and see what happens.

Thank you for your reply! I outputed it with MATLAB by myself, therefore, it could happen that there are many problems with the surface norm or other things. I will check my code, if something nice happens, I will let you know.

I can send you the stl file. I wish you could take a look when you are free. I think you can easily understand the problem when you load it in your ultimaker cura. Thank you. tritext.stl

Yes, you are right. From the x-ray view, we can find no problem. However, I think from the layer view, you could see the differences. The holes or called voids can not be printed properly, as they divided the voids into several slices and between the slices there are walls to divide them. The reason I want to print it in this way is that I want to print foam like structure according to my mathematical models for experiments not for fun. Therefore, it is not that important they are visible or not.

At first, thank you for your reply! I attached 2 screen shots. On the left side is the layer view. You can not see the bottom of the left huge bubble. However, from the right graph you can see the shape of the bubble, which does not include a horizontal surface. Therefore, I think it divide my bubble into different slices and create horizontal walls between.

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?
