Additive Manufacturing (AM) has significantly reshaped the industrial sector by enabling the production of intricate and customized components with an unparalleled level of precision. Traditional manufacturing techniques, particularly subtractive processes, often struggle to achieve the same level of design complexity and efficiency. Unlike these conventional methods, AM constructs parts by systematically adding material in successive layers. This unique fabrication approach maximizes design flexibility, minimizes material waste, and enhances production efficiency. As a result, AM has gained widespread adoption in industries such as aerospace and automotive, where lightweight, high-performance components are in constant demand. Among the various AM technologies, Direct Energy Deposition (DED) has emerged as a highly effective method for manufacturing fully functional metal parts while reducing material waste.
