Michael Hansmeyer and Benjamin Dillenburger are the architects behind Tor Alva. They aim to showcase the potential of 3D printing with concrete and emphasize how this technology can reduce material consumption in construction. Their goal is to push the boundaries of design and explore the possibilities offered by 3D printing.

Benefits of 3D Printing with Concrete

Reducing Material Consumption in Construction

The use of 3D printing with concrete in construction allows for precise application of the material, reducing waste and minimizing material consumption. This technology enables architects and engineers to optimize the use of concrete in their designs, resulting in more efficient and sustainable structures.

Precise Application and Minimizing Waste

With 3D printing, concrete can be applied precisely where it is needed, minimizing waste and improving overall construction efficiency. Unlike traditional construction methods, where excess materials often end up as waste, 3D printing allows for a more targeted and controlled use of concrete, reducing environmental impact.

Complex Geometries and Bespoke Components

One of the key advantages of 3D printing with concrete is the ability to create complex geometries and bespoke components. This technology enables architects to design structures with intricate and unique shapes that would be difficult or costly to achieve using traditional construction methods. It offers a new freedom of design and opens up possibilities for innovative architectural solutions.

The Printing Process and Design of Tor Alva

The Concrete Extrusion Process

The concrete extrusion process used in the construction of Tor Alva involves the use of robotic arms to 3D print the concrete structures. The concrete is extruded layer by layer, following a pre-designed digital model. This process allows for precise control and customization of the printed structures.

Integration of Rebar and Post-Tensioning System

To ensure structural strength, rebar is integrated into the 3D-printed concrete columns during the printing process. Additionally, a post-tensioning system is used to further enhance the strength of the columns. These measures enable the construction of a 30-meter-tall tower while maintaining structural integrity.

Unique Geometric Patterns on Tor Alva’s Structure

The 3D-printed concrete structures of Tor Alva feature unique geometric patterns on their surfaces. These patterns are a result of the design freedom afforded by 3D printing and demonstrate the aesthetic possibilities of this technology. The intricate textures add visual interest to the tower’s overall design.

Challenges and Solutions

Thin-Shelled and Hollow Columns

One of the challenges faced during the construction of Tor Alva was creating thin-shelled and hollow columns that reduce material usage while maintaining structural strength. This was achieved through the integration of rebar and a post-tensioning system, ensuring the columns’ stability and durability.

Structural Strength and Height

As the world’s tallest 3D-printed structure, Tor Alva required careful consideration of its structural strength and stability. By incorporating rebar and a post-tensioning system during the printing process, the architects were able to achieve the necessary strength to build the 30-meter-tall tower.

Formwork-Free Fabrication

Traditional construction methods often require formwork for the pouring and shaping of concrete structures. However, 3D printing eliminates the need for formwork, reducing material usage and construction time. Tor Alva showcases the possibilities of formwork-free fabrication through its 3D-printed concrete columns.

Current Progress of Tor Alva

Number of Completed Structural Columns

As of now, eight out of the 32 structural columns of Tor Alva have been 3D-printed. The construction process is progressing steadily, and the tower is on track for completion later this year.

Location and Expected Completion Date

Tor Alva is being constructed in Mulegns, Switzerland, in the Swiss Alps. The tower is expected to be completed by the set deadline, becoming the tallest 3D-printed structure in the world.
