Abstract
The present study refers to 3D metal additive manufacturing (MAM) from an interdisciplinary perspective, providing an overview on sustainability, basic principles, and a conceptual framework on environmental performance, implicit constraints regarding materials, recycling and use/reuse tools for extended life cycle, regarded as the trendiest manufacturing processes in terms of material consumptions efficacy and energy efficiency. The demand for integrating MAM technology as a means to boosting sustainability in industry is based on its capacity to use smart or custom-designed materials to generate special geometries, unobtainable otherwise, allowing for further part optimisation or redesign. The outlined advantages and challenges of the new MAM processes and advanced technologies for functional objects and durable products underline the high interest in this area. Results from the literature and our MAM research interest indicate that some metal powder (MP) recycling and use/reuse technologies could be developed to save MP, as could MAM applications in component redesign and repairs to increase sustainability. The achievement has a high degree of generality and serves as a basis for future MAM sustainable methods.
Highlights
In modern production and the Industry 4.0 era, many industries like aerospace, automobile, medicine, maritime, arts, and other fields open new paths for metal additive manufacturing (MAM) [1]
All new data obtained from the specific environmental assessments (LCAs) provided by researchers and industry should be integrated in the lifecycle inventories (LCIs) databases according to the new processes for recycling, re-design, and repair tools to raise the sustainability performance for MAM technology
The sustainability performance of MAM technology depends on the involved metal powder quality and lifecycle, so powder recovery and recycling optimisation is a major research topic and industrial need
Summary
In modern production and the Industry 4.0 era, many industries like aerospace, automobile, medicine, maritime, arts, and other fields open new paths for metal additive manufacturing (MAM) [1]. As many manufacturers do not have knowledge of effectively optimal design for parts from AM processes and how to integrate these technologies in the traditional manufacturing models, there is a lack of international product standards and process certification for widespread MAM adoption for large amounts of commercial parts [1,4,7,9]. Several standardisation organisations, such as the ASTM F42 Committee, ISO TC/261 Committee, and a few manufacturers, are making efforts to elaborate a set of standards for AM, taking the sustainability aspects into consideration. Some perspectives conclude why the research topics presented in this work offer a great perspective for using MAM technologies as methods for raising sustainability performance, and some significant conclusions are offered
