Models like this are often digitally ‘sculpted’ in mesh modelling softwares like blender. All my experience is using parametric CAD software, where you use planes and fully dimensioned sketches to create 3D geometry. Interestingly, I followed the basic principles of how to model this head using clay in order to figure out a method for modelling this head using CAD. I use Solidworks to do my modelling, but this process can be followed using any other parametric CAD program.

This head is part of a mechanical kinetic sculpture that I’m working on. Stay tuned for more!
