Mesh Mould and In situ Fabricator, 2016-2017
in the DFAB HOUSE
The in situ fabrication of a doubly curved reinforced concrete wall featuring the Mesh Mould technology realises the first innovation object of the Empa NEST DFAB HOUSE. The S-shaped slender wall in the ground floor of the living unit follows the structural principle to increase stiffness through local undulations of the surface geometry. The freeform reinforcement cage is fabricated by the mobile construction robot IF through continuously bending and welding 6mm rebar in vertical layers. The onboard sensing and computation system of the robot allows to construct the mesh without any external measurement devices. It orients itself relative to the foundation of the wall, which is installed prior to the robotic construction and equipped with markers and tags. A camera on the end effector measures the tags for localizing the robot, and two more cameras monitor the accurate fabrication of the mesh.The concreting of the wall consists of first filling the mesh with a custom developed concrete mix and then finishing the surface with a layer of shotcrete.

The research and building project is pursued in the framework of the National Competence Centre of Research (NCCR) Digital Fabrication.
