Abstract

New sustainable technologies, such as additive manufacturing (AM), have recently been adopted in the construction industry, significantly reducing construction completion times and effectively repairing and remanufacturing components. While AM's implementation in construction is still diffuse, this review contributes to a better understanding of how this technology is interpreted and utilized, exploring the main trends in AM within the construction industry. The systematic review of recent publications identified eight critical topics for AM, whose processes are characterized by their materials: aggregate-based materials, metals, and polymers. The findings reveal an increase in the published works, with the United States, Germany, and China rising as the prominent contributors, where AM technologies are mainly defined by processes such as Material extrusion, Particle bed, Powder bed fusion, Directed energy deposition and Vat photopolymerization. Finally, other challenges regarding AM in the construction industry, such as its role in large-scale construction and prefabrication, are also discussed.

建筑行业的增材制造

新的可持续技术，如增材制造（AM），最近被用于建筑行业，大大缩短了施工完成时间，有效地修复和再制造组件。虽然AM在建筑中的实施仍然是分散的，但这篇综述有助于更好地理解这项技术是如何被解释和利用的，探索AM在建筑行业中的主要趋势。对最近出版物的系统回顾确定了增材制造的八个关键主题，其工艺以其材料为特征：聚集体基材料，金属和聚合物。研究结果显示，已发表的作品有所增加，美国、德国和中国是主要贡献者，其中增材制造技术主要由材料挤压、颗粒床、粉末床融合、定向能沉积和还原光聚合等工艺定义。最后，还讨论了AM在建筑行业中的其他挑战，例如其在大型建筑和预制中的作用。
