Patterns inspired by lobster shells can make 3D-printed concrete stronger to support more complex structures, according to new research.

The natural strength of lobster shells inspired the research team.

In a new experimental study, researchers at RMIT University looked to the natural strength of lobster shells to design 3D printing patterns. Their bio-mimicking spiral patterns improved the overall durability of the 3D-printed concrete, as well as enabling the strength to be precisely directed for structural support where needed. Combined the twisting patterns with a concrete mix enhanced with steel fibres resulted in a material was stronger than traditionally-made concrete.Read more from The Construction Index
