In Remmeltshofen stands a building whose walls were not built using conventional methods but were printed using the mobile 3D printer Karlos. Those responsible see the innovative joint project by the companies Putzmeister, Schwenk and Rupp as a significant step forward for the construction industry and a powerful signal toward digitalization and sustainability.
In just 29 printing hours the building in Remmeltshofen with a floor area of 95 square meters (10 x 9.5 m) was printed. No lengthy setup or formwork was needed – the mobile 3D printer Karlos from Putzmeister was ready to go in less than an hour and began, layer by layer, to build the structure, which serves as a local community center. The company developed the fully electric construction machine specifically for such projects.
"This project is a crucial step towards further industrializing construction with additive manufacturing," says a spokesperson from the responsible construction company Rupp. "Here, digital planning and calculations merge with the use of advanced materials and innovative printing technology to create a completely new approach to building." In the next step a multi-family home will be printed using the same technology – proof that 3D printing is scalable for larger projects as well.
