Prefabrication with Smart Dynamic Casting , ETH Zurich, 2016-2018
Smart Dynamic Casting (SDC) is a continuous robotic slip forming process that enables to prefabricate material optimized load-bearing concrete structures. In this automated process a dynamic formwork significantly smaller than the structures produced is continuously moved and filled with concrete, in a velocity that enables to shape the concrete in the delicate phase when it changes from a soft to a hard material. During the first phase of SDC architectural scaled columns proved that concrete can be shaped in its delicate transition from soft to hard in a robotic process (see Smart Dynamic Casting, ETH Zürich , 2012-2015). The second research phase at the National Competence Centre in Research (NCCR), SDC was modified into a suitable setup for prefabrication, for the fabrication of non-standard loadbearing elements. The current research is dedicated to the development of a fully automated robotic slip forming process, for the production of reinforced façade elements with a minimal cross section of 70 x 100 mm for the DFAB HOUSE at the Empa premises in Dübendorf (see ). This includes developing a flexible formwork system that enables to shape concrete of minimal dimensions in a slipping process-, and to automated the material processing in which the hydration of the material can be controlled. These developments are undertaken in a interdisciplinary set-up in which architects, mechanical engineers and concrete material scientists together target the goal of producing non-standard concrete structures using a single formwork.
