Robot-Assisted Flow-Production-Processes Tool-Development for the Fabrication of Thin-Walled Fiber-Reinforced Concrete Elements (2022-09)¶

Spray extrusion, especially in combination with a thin layer of sprayed concrete and ribbed support structures, for example for facade elements, results in very efficient components with high load-bearing capacities and high-quality surfaces. The developed combined spray-extrusion nozzle offers the possibility of both: spraying and extruding, adapted mortar and concrete. Based on characteristic value determinations, practicability and the increase in productivity could be proven. This increase in productivity at the additive manufacturing leads to positive economic effects, applications of high-strength lightweight structures in construction become more attractive, and it enables the serial implementation ib of free-formed modular constructions.
