Evaluation of a metallic AM process as a sustainable alternative in the construction of structures

Abstract

Metal additive manufacturing has emerged as an innovative technology, enabling the creation of complex geometries and the design of virtually limitless parts. This study aimed to compare metal additive manufacturing with traditional structural construction methods, based on criteria of sustainability, efficiency, and technical feasibility. The methodology employed was a mixed-methods, descriptive approach, supported by a literature review of scientific articles and academic research, complemented by a comparative analysis of aspects such as energy consumption, material utilization, waste generation, costs, and design flexibility. Metal additive manufacturing allowed for the optimization of material use, a considerable reduction in waste, and greater independence in the design of structural components. However, it presented limitations related to initial investment and energy consumption in certain processes. Metal additive manufacturing represents a viable and sustainable alternative for structural construction, geared towards the development of more efficient and responsible construction processes.
