Zaha Hadid Architects, 3D Printed Concrete Bridge Made of Blocks

Designed and developed by Block Research Group (BRG) at ETH Zurich and Zaha Hadid Architects Computer and Design Group (ZHACODE), in collaboration with Inkremental3D (in3D) and Holcim, Striatus is a 3D printed concrete bridge that does not require mortar or reinforcement, the first of its kind. The bridge is made possible by combining traditional construction techniques with advanced computer design, engineering and robotic manufacturing technologies . Striatus can currently be seen in the Giardini della Marinaressa during the Venice Architecture Biennale until November 2021.

By integrating 3D printing into the manufacturing process, the team involved in developing Striatus were able to build it more precisely using fewer materials than traditional concrete construction. The name Striatus reflects its origin; The concrete blocks are orthogonal to the main structural forces to create a “striped” pressure-only structure. Mortar or other reinforcements were not required. Because of this, the striatus can be disassembled and reassembled in a different location and recycled when it is no longer needed.
