September 2016

On the event of the 77th USH congress (Union Sociale pour l’Habitat, the French organisation for social housing), XtreeE 3d-printed a new concrete wall, in collaboration with Habitat 76 (Seine-Maritime’s main housing association). The wall is 2.5m long and 2m high. It took XtreeE’s team about five and a half hours to 3d-print it, in a single continuous manufacturing process, using experimental cement developed by LafargeHolcim R&D and ABB’s IRB8700 industrial robot. The design is based on an internal double sine structure that XtreeE already experimented with in previous projects (see here or here). The wall also integrates an element designed as seating, 3d-printed alongside the rest of the geometry. This wall marks the beginning of XtreeE’s collaboration with Habitat 76, a collaboration that will be continued within a project aiming at the production of a 3d-printed housing unit in 2017. This new project is an opportunity for XtreeE to pursue its research for the reduction of construction costs and the improvement of building performance.
