Industry 4.0 and Sustainability in Additive Manufacturing

Industry 4.0, which represents the integration of digital technologies such as big data, Internet of Things (IoT), and artificial intelligence (AI), inside the manufacturing pole are evidently shadowing the additive manufacturing (AM) process. AM, specifically fused deposition modeling (FDM), enables the production of complex geometries with little to no waste material; thus, it is helpful for sustainability issues, as it reduces energy consumption and allows the use of recycled materials. The sustainability of the digital powder bed fusion (PBF) process used to produce personalized helmets will be covered in this chapter. The enormous volume of data that can be gathered by Industry 4.0 technologies will be discussed, as well as the hitherto unheard-of levels of resource optimization, efficiency, and customization that manufacturers may attain. An IoT-enabled system provides real-time monitoring, digital twin simulations for design optimization, and 3D scanning that enables accurate consumer data collection. The potential of FDM in ecologically friendly production, while satisfying customer needs from industrial, medical, and sporting applications is demonstrated in a case study for the manufacture of custom helmets. An examination of important sustainability measures, including lifetime assessment, material efficiency, and localized production, is used to investigate the environmental benefits. The challenges include skill deficiencies in the workforce and hefty startup costs. These include blockchain supply chain transparency and smart materials. Thus, this chapter presents a unified viewpoint, backed by research results, on how AM and Industry 4.0 can promote sustainable manufacturing methods, resulting in additional advancements and consequences for the design of customized products.
