Iterations and refinements were made to optimize the design for 3D printing technology and structural stability.

Printing process and technology used

The printing process for the White Tower involves the layer-by-layer deposition of concrete material to create the desired shape and structure. The custom-designed 3D printer developed by ETH Zurich utilizes a combination of extrusion and robotic arm technology to precisely position the printing nozzle and control the flow of concrete. This advanced printing technology allows for the creation of complex geometries and intricate details that would be difficult to achieve through traditional construction methods.

Description of the custom-designed 3D printer

The custom-designed 3D printer used for the White Tower project is a state-of-the-art machine specifically tailored for large-scale construction printing. It features a robust frame and a precise positioning system to ensure accurate printing. The printer is equipped with a high-capacity concrete extruder and a sophisticated control system that monitors and adjusts the printing parameters in real-time. This allows for precise control over the printing process and ensures the quality and integrity of the printed structure.

Number of layers printed

Approximately 4000 layers are printed to construct the White Tower. Each layer has a height of approximately 6mm, resulting in a total height of 30 meters for the completed structure. The layer-by-layer printing process ensures the gradual buildup of the tower’s form and enables precise control over its geometry.

Segment printing and on-site assembly

To facilitate the construction process, the tower is printed in separate segments off-site. These segments are then transported to the construction site, where they are assembled to form the complete structure. This approach allows for efficient printing and assembly, as well as easier transportation of the printed components. The segments are designed to fit together seamlessly, ensuring structural integrity and stability.

Structural Stability and Reinforcement

Importance of structural stability in construction 3D printing
