Sustainable ribbed concrete floors with 3D printed formwork

In the search for sustainable building solutions, concrete floor slabs are a key challenge due to their high carbon footprint. Harnessing digital fabrication tools, a research team has explored a novel 3D printed plastic formwork to produce optimised ribbed floor slabs in an efficient manner. The new approach uses 40 percent less concrete, while offering the same structural performance. The project was led by the chair of Walter Kaufmann in collaboration with Gramazio Kohler Research.
