The increasing digitalisation and automation in the construction industry is placing new requirements on concrete production and processing. In the field of additive manufacturing in construction, particularly the Shotcrete 3D printing process, reproducible recipes, short reaction times and precise coordination between the mixing, pumping and printing processes are crucial for building components layer by layer. Against this background, a mixing plant specifically designed for 3D concrete printing was developed for the Digital Building Fabrication Laboratory (DBFL) in a collaboration between the Institute for Structural Design at Technical University Braunschweig and Kniele GmbH.
