What you're seeing is that Rhino, on exporting it to a format for printing, is approximating those curves with straight lines. While 3D printing with true curves is indeed possible, Rhino doesn't export gcode that does so; instead, you're presumably exporting to STL or OBJ, which reduces curved surfaces to mesh.

If you want smoother curves, you need to export at a higher resolution. I don't work with Rhino so I can't give you details there, but if you search for 'Rhino export stl', you'll find plenty of tutorials showing how to adjust that resolution.

Hi, I am trying to print this model created in Rhino and exported as a .OBJ and when it prints in PLA there appears to be ribs protruding through the skin, when it should be smooth ...anyone have an ideas please ...?

Thanks
