Basic principles of 3D concrete printing in the light of sustainable development

Abstract

Although conservative, the construction industry must be transformed in line with new technologies. Adopting the concept of 3D printing can provide a handful of benefits in terms of creativity, flexibility, less waste generation, more efficient energy consumption as well as lower carbon emissions. The aim of this paper is to summarize the basic principles of 3d concrete printing, discussing the main goals and shortcomings that must be considered and resolved before wider application. Also, a review will be given on the production technology and materials used, as well as the sustainability of buildings built using the concept of 3d printing.
