Tool developments for additive manufacturing processes with anchor for the modern flow production

In modern flow production, the focus is on the continuous digitally controlled tools within the context of the digital twin. Spray extrusion, especially in combination with a thin layer of shotcrete and ribbed supporting structures, for example for facade elements, leads to very efficient components with high load‐bearing capacity and high quality surfaces. The developed combined spray extrusion nozzle offers the possibility of both: spraying and extruding, adapting mortar and concrete. In addition, automated integration of anchors is the focus of flow production, for which anchors and tooling systems have been developed. Based on the determination of characteristic values, the practicability and the increase in productivity could and will be proven. This data forms the basis of a digital twin in preparation for Industry 4.0. This increase in productivity in additive manufacturing leads to positive economic effects, applications of high strength lightweight structures in construction are becoming more attractive and enable the series implementation of free form modular constructions.
