Multilevel Design Approach to 3D Printed Concrete Elements

The development of 3D concrete printing technology (3DPC) leads to the possibility of constructing more efficient and sustainable buildings. Automation in construction could lead to a reduction in construction time and the use of building materials through the application of topological optimisation. This study first discusses the benefits of 3DPC, especially in terms of sustainability and energy consumption for heating/air conditioning. Starting from a case study, the design of a 3D-printed concrete wall is presented, and finally, the results of a quasi-static in-plane cyclic test, performed at the University of Brescia, on a 3DPC wall are presented.
