3D printing under construction: clubhouse in Remmeltshofen built with KARLOS mobile printer

An innovative construction project in Remmeltshofen demonstrates the possibilities of 3D printing in the construction industry. The local clubhouse was built in just 29 printing hours using the KARLOS mobile 3D printer. This joint project between the companies Putzmeister, SCHWENK and Rupp represents a significant step towards digitalization and sustainability in the construction industry.

The KARLOS printer, developed by Putzmeister, is an all-electric construction machine specially designed for the 3D printing of buildings. In contrast to conventional construction methods, the walls of the clubhouse were built directly on site, layer by layer, without formwork. The footprint of the building is 95 square meters (10 x 9.5 meters), and the precise execution illustrates the potential of additive manufacturing in construction.

SCHWENK supplied a special concrete mix that contributes to the sustainability of the project thanks to its low CO₂ emissions and optimal use of resources. This concrete mix not only enables a faster construction time, but also protects the environment, which is becoming increasingly important for modern construction projects.

“This project is a decisive step towards the further industrialization of construction with additive manufacturing,” says a spokesperson for the construction company responsible, Rupp. “This is because digital planning and calculation are actually merging with the use of advanced materials and innovative printing technology to create a completely new approach to construction.

The collaboration between Putzmeister, SCHWENK and Rupp shows how high levels of automation and innovative technologies can change the construction industry. Integrating 3D printing into the construction process increases efficiency and sustainability, which could fundamentally change the way buildings are constructed in the long term. This project in Remmeltshofen serves as a living example of the practical application of 3D printing technologies in the construction industry and lays the foundation for future developments in this area.
