N2 - During the summer semester 2018–2019, a 3D concrete printed (3DCP) pavilion consisting of 47 unique free form parts was realized in the central square of the engineering campus of the University of Innsbruck. In a period of just 11 weeks, it was designed, engineered, manufactured, and assembled on-site to provide an attractive meeting space for students and staff alike. The parts were printed off-site in an extrusion layering process, using variable print speeds and filament heights to obtain radially fitting segments that were transported to the building site. A selection of parts was reinforced with innovative woven carbon fiber reinforced polymer (CFRP) strands, while the others were reinforced with in-laid conventional reinforcement bars. The parts were bolted to an on-site cast fibre-reinforced concrete floor and the seams were sealed with a silicone adhesive. This paper presents the entire project, including architectural considerations, geometrical parametric modelling, structural (safety) principles and design, manufacturing, and construction, including connections.
