Engineering firm Arup and architecture studio CLS Architetti 3D printed a concrete house using 3D Concrete printing technology for Milan Design Week. The 100-square-meter house, built in one week on Piazza Cesare Beccaria, consists of 35 modules featuring curved walls, a living area, bedroom, kitchen, and bathroom.
The house was printed using a robot by CyBe Construction and a special concrete mix developed by Italcementi. The printing process took 48 hours of active time, with each wall section taking about an hour to complete and curing in five minutes. The robot can be programmed to create different sizes or shapes, including furniture.
Though a prototype, the project aims to demonstrate that 3D printing can quickly and cost-effectively create housing. CLS Architetti envisions this technology being used to build anywhere, even on Mars, with flexible designs and faster construction. After Milan Design Week, the house will be reassembled at Italcementi’s headquarters.
The project also highlights how 3D printing reduces waste by reusing materials and improving construction efficiency. Arup sees it as part of a shift toward more sustainable building practices.
