Aplicações, desafios e impactos causados pelo uso da impressora 3D na construção civil: uma revisão de literatura

Abstract

The construction industry, a fundamental sector of the Brazilian economy, faces significant challenges in improving productivity, reducing costs, and incorporating sustainability into its construction practices. In this context, 3D concrete printing stands out as an innovative technology with the potential to significantly enhance the industry's performance. This study aims to better understand this potential by conducting a literature review on the applications of 3D concrete printing in construction, covering the period from 2019 to 2024. The research investigates the characteristics, advantages, and disadvantages of the technology, as well as explores opportunities and challenges for its integration into the sector through practical cases and recent studies. The results show that 3D printing can significantly reduce material waste (by up to 60%), increase productivity, and lower construction costs, while also promoting sustainability. However, the adoption of this technology in Brazil faces specific challenges, such as a lack of regulations and funding. This study contributes to understanding the impact of 3D concrete printing in the context of the Brazilian construction industry, paving the way for the adoption of more innovative, sustainable, and efficient practices
