The purpose of this study is to design a sustainable metal recycling process through its use as a raw material for the manufacture of a powder that will supply a 3D printer. Will be investigated all the tests performed with the actual product, verification of mechanical properties and a comparative study with components produced through traditional processes. However, the discussion is to verify the feasibility of the implementation of Additive Manufacturing (AM) through Circular Economy (CE) practices, listing the processes and methods for all stages of the process and how the model could benefit the sustainability within an industry. With approaches of the literature review, followed by a field research in junkyards toward exploring the use of metal scrap, applying focus groups interviews with experts of a multinational automotive industry, followed by the proposal of a conceptual model for the treatment of scraps and finally tensile strength tests were conducted on specimens printed in PLA for characterization of the material. Therefore, the contributions of this work cover the unification of the technologies of 3D printing with sustainability and immersion in a real productive supply chain, developing a new model to support the chain of scraps. It can be inferred through the results of the tensile strength tests the real influence of the 3D printer s parameters in the final component and acquire knowledge for future research. It is also concluded that the results of the interviews with expert engineers, field surveys and literature review that the model can be used to reinsert the scrap as raw material to make products on demand, and may then have social and environmental implications at a time of rapid change of technology, establishing a sustainable model that recycles waste materials such as scrap, a notable problem in Megacities.
