Microstructure after failure
All cellular material designs were tested mechanically under uniaxial compressive loading
Strength-to-weight ratios of various materials tested can be seen here with comparison to natural structures such as honeycomb and bone

Researchers in Germany have developed a lightweight, high-strength material inspired by the framework structure of bones and wood and the shell structure of bees' honeycombs. Created using 3D laser polymer printing combined with a ceramic coating, the material is less dense than water but, relative to its size, boasts strength comparable to high-performance steel or aluminum.
