This could be used as an infill for 3D printed parts.
It is a superposition of simple cubic infill with an
octahedral infill (octet truss with filled in faces) of halve the size.
A "cubic-octahedral" infill - so to say.
**It comes from this paper:**
"Mechanical metamaterials at the theoretical limit of isotropic elastic stiffness".

The orientation is here chosen such, that
no planes are coplanar to the printbed.
