Aplicação e desafios da impressão 3D na construção civil: um protocolo de revisão sistemática

Abstract

This Course Completion Work (TCC) evaluates the viability of 3D printing in construction, highlighting its impact in terms of cost, time, sustainability and durability. The research, conducted through a systematic review, reveals that 3D printing can transform the sector by significantly reducing costs and construction time, as well as minimizing material waste. The technology allows the creation of complex structures with high precision and offers sustainable solutions, such as the use of recycled materials and the reduction of the environmental footprint. Compared to traditional methods, 3D printing can reduce costs by up to 60% and construction time by 70%, in addition to providing long-term savings due to the durability of the structures. However, large-scale implementation faces barriers, such as the lack of standards, the high initial cost of equipment and the need to adapt professionals and traditional processes. Questions about the durability and quality of 3D printed constructions also need to be further investigated, especially in relation to resistance to environmental factors and adhesion between layers. The study suggests that, with the continuous development of technologies and the creation of regulatory standards, 3D printing has the potential to consolidate itself in the future of civil construction, offering innovative and sustainable solutions. Despite the challenges, the growing adoption of additive manufacturing in the sector demonstrates that the technology can be a viable alternative to meet the demand for faster, more economical and ecological construction, significantly contributing to the advancement of the construction industry.
