3D printing, compared to traditional methods like casting concrete in formwork, revealed important economic, environmental and constructability advantages – however, there are still fundamental requirements to be met, including adequate thermal behaviour.
The work begins with assessing the thermal behaviour of 3D printing solutions for walls already developed, followed by the study of strategies that can improve their hygrothermal behaviour. The final objective is to optimize the solution that fits the restrictions associated with 3D printing technology. The project is a collaboration with the Department of Civil Engineering from the University of Porto, Portugal.
