Apartment buildings Metzingen
An innovative residential construction project is being built in Metzingen-Neugreuth, where ZÜBLIN is using 3D concrete printing to create an entire storey directly on the construction site for the first time. The process enables fast, precise and CO₂-reduced production of the load-bearing walls.
In Metzingen-Neugreuth, GWG Reutlingen is currently building a pioneering residential construction project with three apartment buildings and a total of 44 residential units, including publicly subsidized and barrier-free apartments. The new building is being constructed on a plot of around 3,000 m² and combines conventional construction methods with an innovative 3D concrete printing process. For the new building, ZÜBLIN and INSTATIQ are using a large-format 3D concrete printing process directly on the construction site for the first time in Germany - a milestone for the entire construction industry.
3D-printed top floor
A central element of the project is the top floor of one of the buildings, the load-bearing walls of which are created directly on the construction site using 3D concrete printing. The Instatiq P1 concrete printer used creates solid wall components with heights of up to three meters and wall thicknesses of between 16.5 and 19 cm. Production takes place in shifts and is fully automated using a 26-metre boom.
Efficientand precise construction
The automated printing process produces the complete wall structure of the storey within a few days. The digital control system minimizes deviations between planning and execution and reduces the amount of formwork required. The concrete mix used produces around 20% less CO₂ than traditional limestone masonry.
Model residential construction
With this project, GWG Reutlingen is testing an alternative construction method for future projects while creating modern living space in the region. Completion is scheduled for May 2026. Further applications of 3D concrete printing are in preparation and will be made available via the joint venture between INSTATIQ and ZÜBLIN under the name NELCON.
