Founded in 2015, XtreeE is a French startup specialising in large-scale 3D printing for construction. Thanks also to its advanced technology, which is protected by ten inter - national patents, XtreeE has become a major player in the market of 3D concrete printing. Further development and optimisation are on the agenda at XtreeE. This could involve smaller changes, whose influence on the result is then determined, or also larger investments, such as the new Kniele mixing plant, which was supplied by the French company Beton Stone Consulting (BSC), Kniele's representative in France.
