A literature review to determine the availability of materials for application in 3D printing processes within the Brazilian construction industry

Abstract

In the present day, the civil construction industry grapples with various challenges, including low productivity, a shortage of skilled labour, resistance to technological innovations, and significant environmental impacts. Extensive literature underscores the urgency of modernizing the sector by embracing new technologies such as digital prototyping and advanced manufacturing processes. In light of these considerations, this article aims to assess the range of materials available for 3D printing to determine the feasibility of integrating this technology into the Brazilian civil construction industry (BCI). Through a comprehensive analysis of materials currently in use, drawn from scientific research, it becomes evident that mortar-based materials are emerging as a preferred choice for 3D printing components within civil construction. Considering that the Brazilian construction sector already heavily relies on cement as its primary material for constructing the built environment, a promising landscape unfolds for the gradual adoption and integration of three-dimensional printing technology into the industry. This alignment with existing practices and materials positions the BCI favourably for embracing the potential of 3D printing.
