Warehouse Weilimdorf

Putzmeister and ZÜBLIN are setting a milestone for digital and automated construction with the world's first building made of load-bearing standard concrete walls using the 3D printing process. For STRABAG BMTI's new warehouse in Stuttgart-Weilimdorf, a process was used for the first time that makes 3D concrete printing scalable for solid construction - and thus paves the way for future large-scale projects.

Technology highlight: the mobile 3D concrete printer

The heart of the project is the mobile 3D concrete printer, which is based on a truck-mounted concrete pump. An automatically controlled boom with a reach of 26 meters applies the concrete precisely, layer by layer and without formwork. The system follows a digital construction plan exactly and enables the production of storey-high, load-bearing and room-enclosing concrete walls.

Key advantages of the technology

• High reach and flexibility thanks to mobile construction machine
• Precise and fully automated concrete application
• Load-bearing solid wall cross-sections in just one work step
• Significantly less manual work on the construction site
• Ideally suited for scalable large-scale projects

The 3D printer from INSTATIQ overcomes a key weakness of conventional gantry printers: their limitation to smaller buildings. The new mobile solution enables 3D concrete printing on an industrial scale.

Sustainable construction through CO₂-reduced concrete and electrified processes

The project shows how 3D concrete printing and sustainable construction can go hand in hand:

• Use of CO₂-reduced concrete mix designs
• Fully electric machine with 100 % green electricity
• No need for time-consuming formwork work
• Resource-saving production through automated processes
  

With these measures, Putzmeister and ZÜBLIN are significantly reducing the ecological footprint of concrete construction and making a contribution to climate-neutral construction.
