Advantages

Specific modulus and strength evidently higher than Gyroid structure as relative density increases

Strength under dynamic loading apparently higher than static results

Specific energy absorption superior to traditional honeycombs and lattice structures

Diamond structure with density gradient exhibited the highest specific energy absorption
