Abstract. The processing of cementitious materials is the technological core of the modern construction. In the recent years new construction techniques such as 3D concrete printing have been developed opening plethora of opportunities and technological advancements such as no need of formwork (considerable time and cost reductions), high geometrical flexibility and low dependency on skilled labor. However, the main significance and revolutionary potential of 3D concrete printing is seen in the context of Construction Industry 4.0 since it offers a logical and highly desired step from the already well developed tool of digital design and planning (CAD, BIM, etc.) towards the digital manufacturing, thus making construction a fully digitalized seamless process. This article provides a short overview of the recent research activities at the TU Dresden in the field of 3D-printing in concrete construction.
