Germany's first officially approved single-family house built using the 3D concrete printing process is now located in Beckum in Münster. The installation of a Bette bath and two Bette shower trays proves that this is a visionary, quality-driven and sustainable model project. For planners and architects, 3D printing means a high degree of design freedom in the design of buildings. If the technology catches on, they will be able to realise shapes in the future that would only be feasible in conventional construction at great financial expense. The two-storey residential building in Beckum with around 160 square metres of living space was also first created three-dimensionally on the computer before the 3D concrete printer printed everything out with centimetre precision. And that was done in the course of just a few days. How does it work? The print head spits concrete out like cream from a squirt bag. At a speed of up to one metre per second, it moves along its programmed path on a permanently installed metal framework. Layer by layer, the walls of a building grow upwards.
