Conventional construction of concrete shells involves a costly and time-consuming erection of custom formwork. An alternative approach that avoids this is an on-site assembly of shells from prefabricated modules. This article presents a new, highly automated method for the production of such modules. The proposed method combines the technology of full-width 3D concrete printing using strain-hardening cement-based composite and the technology of robotic textile mesh production from mineral-impregnated carbon yarns.
