Impressão 3D com argamassa para fôrmas permanentes: estado da arte

Abstract

This research presents a literature review on the state of the art of 3D printing with mortar applied to the production of permanent formwork for civil construction. The study aimed to investigate mortar formulations, reinforcement strategies, structural performance, and adhesion between materials in construction systems that integrate 3D printing. To this end, scientific articles available in the ScienceDirect database, published after 2020, were selected, focusing on peer-reviewed studies that address structural aspects of the technology. The results of the analysis show that 3D printing of formwork, when associated with optimized materials and reinforcements, can outperform conventional molded systems, promoting greater strength, less cracking, and better interfacial adhesion. Furthermore, the technique allows for a significant reduction in waste generation and dependence on specialized labor, reinforcing its potential as a sustainable and efficient alternative for streamlining construction processes.
