I recently stumbled upon Vitaly Bulgarov's works and he did some mechs/robots with wireframes limbs (not sure about the name actually) like this one :

I tried using combinations of Wireframe modifier + Subsurf modifier + bevel modifier, the problem is, with a simple small sized plane, you quickly reach 1 million vertices.
If you watch carefully, in the picture, the holes are not circular (which could be achieved by simply using the subsurf and doing inset > delete face so all holes are circles, though it also requires a lot of vertices), but here they are squary.
The biggest issue that I have is that the wireframe modifier gives very sharp/ugly geometry which I would like to avoid.
