The Institute for Experimental Architecture/Hochbau is part of the Faculty of Architecture at Innsbruck University and headed by Prof. Marjan Colletti. Since the establishment of the Robotic Experimentation Laboratory—REX|LAB in 2012, robotic fabrication methodologies have been a pivotal research trajectory for the institute. Currently, in cooperation with the industry, the Institute of Experimental Architecture/Hochbau is developing 3D concrete-printing processes—finally 3D printing should become relevant for large-scale building elements. While small-scale 3D printing has meanwhile become an easy-to-access technology, we aim to use industrial robots in combination with concrete to engage with architecture beyond printing mock-ups. Large-scale concrete printing has to challenge the influence of gravity caused by its own weight at a high level, since the material needs to provide initial stability as well as low cure times. The material itself, the extruder, the robotic choreography and the path planning, greatly depend on each other and therefore demand precise control of all aspects.
