Europe's largest 3D-printed apartment building in France contains 12 social housing apartments spread across three floors. The project's printing process was carried out in just 34 days. It's positioned next to another very similar building by the same developer, which was constructed using traditional techniques and took three months longer to complete. According to the developers, ViliaSprint is the first building in France in which both the load-bearing structure and all of the walls were printed directly on-site. The curved facade and rounded floor plan are only economical because of 3D printing, complex geometries that would add significant cost with conventional formwork. On-site concrete production further reduces transport emissions, and the optimized form also saved approximately 10% of concrete volume.
