Abstract

This paper examines various additive manufacturing technologies, highlighting their resources, material usage, waste generation, and environmental impacts, along with a detailed descriptions for each type of processes: Material Extrusion, Material Jetting, Directed Energy Deposition, Powder Bed Fusion, Sheet Lamination, Vat Photopolymerization, and Binder Jetting. A detailed comparison emphasizes the applications, materials, accuracy, cost, and sustainability aspects of each process. The findings underline the potential of AM to support sustainable manufacturing through eco-friendly initiatives, like Precious Plastic, while stressing the need for innovations in recycling, waste reduction, and eco-friendly design. This kind of open-source collaboration encourages communities across the globe to develop alternatives to the standard recycling systems.
