Provenly stiffest possible infill! <br><br />
'''This paper:''' <br><br />
"Mechanical metamaterials at the theoretical limit of isotropic elastic stiffness". <br><br />
https://www.nature.com/articles/nature21075 <br><br />
doi: 10.1038/nature21075<br />
<br />
'''The foam achieves the so called Hashin-Shtrikman upper bounds on isotropic elastic stiffness.''' <br><br />
There may be other foams that perform equally well but there provenly cannot be any foams that perform better.<br />
<br />
This could be used as an infill. Both <br> <br />
for today's 3D printing and <br><br />
for future [[piezomechanosynthesized]] structures.<br />
<br />
It is a superposition of simple cubic infill with an <br><br />
octahedral infill (octet truss with filled in faces) of halve the size. <br><br />
A "cubic-octahedral" infill - so to say.<br />
<br />
For overhang free FFF-prnting (or mechanosynthesis) <br><br />
The orientation can be chosen such, that <br><br />
no planes are coplanar to the print-bed. <br><br />
This is on the cost of a bit of the symmetry of the whole block.<br />
