Design and Construction Method of a 3D Concrete Printing Self-Supporting Curvilinear Pavilion

Abstract

In the architectural design field, a practical challenge when producing curvilinear geometry with concrete remains. Currently, the use of three-dimensional printing (3DP) technology with concrete during construction has become of interest for engineers and architects with the expectation to mitigate this type of challenge; however, the level of understanding of the construction process is unclear. This paper will present a case study for the design and construction process for a self-supporting curvilinear geometry architecture termed a multipurpose pavilion. The methods in the case study include computer-aided design, structural analysis, joint assembly, and site construction techniques. The results present the benefits and current limitations of the existing technology and could contribute as a method for 3DP design and construction.
