Rendering to Voxels results in weird artifacts

[NeoN25699]

I have a project in my school that requires a 3d model render of something as fast as I can, and since Cubik Studio is the only modelling software that I have, I tried doing it with this. As I finish the mesh, I tried converting the whole thing into voxels, and somehow it yields these weird artifacts that includes lines across objects. What would be the possible reasons?

Voxelized, notice the floating lines?

Hello, before converting voxel, when you will choose the resolution box, click the box.
