High-performance eco-friendly trimming die manufacturing using heterogeneous material additive manufacturing technologies

The manufacturing industry nowadays has a greater interest in reducing global warming and promoting energy-saving measures than ever before. This has led to the development of eco-friendly manufacturing systems to replace conventional ones. Additive manufacturing (AM) technology, for instance, is expected to contribute to reducing material costs and energy consumption. Unlike conventional material-cutting manufacturing processes, AM enables designs of any shape in manufacturing by adding the necessary parts layer by layer. Direct energy deposition (DED) is one of the many AM technologies available for a variety of commercial steel powders such as P20, P21, SUS420, H13, D2 and other Non-ferrous metal powders. The DED is process that can be applied to various industries, like molding, medicine, and defense. Of these, its application to the molding industry is the most practical, since the process can be used to deposit different materials on existing parts. Using this technology, it becomes possible to manufacture high-functioning parts composed of various materials at reasonable cost. In this study, the DED is used to develop a high-performance and environmentally friendly trimming die. In this study, to develop a high performance and environmentally friendly trimming die using DED, evaluation of mechanical properties of material developed, stress analysis in shear work. The commercialization of the developed technology was evaluated and the commercial application of the developed technology was discussed.
