What do the red spots on my object in UltiMaker mean?
Hello, I'm a bit new to the 3D printing scene. So, I always use Cura UltiMaker to slice my 3D prints. When I finished slicing, these red areas appeared (in the preview). Does anyone know if this object is printable? Thanks in advance! I'm using the Elegoo Neptune 4 Plus. No supports are selected.
