Description
Summary:Additive Manufacturing (AM) processes empower users to design and generate 3D printed models through the utilization of Computer-Aided Design (CAD) software, which are then transformed into stereolithography (STL) files recognized by 3D printers. This approach effectively mitigates many of the drawbacks linked to conventional manufacturing, thereby opening new avenues for sustainable and efficient design practices. Notably, Directed Energy Deposition (DED), a technique within AM, substantially reduces costs associated with component repair and manufacturing. This is achieved by eliminating the necessity for costly tools essential in traditional manufacturing, particularly for crafting intricate components. However, as parts become more intricate and materials more diverse, the challenge emerges of optimizing materials to fully harness their potential in constructing specific components. Consequently, the identification of optimal process parameters becomes imperative, especially for newer, less-tested materials. These process parameters can also be cataloged for subsequent analysis when dealing with similar materials. The research outlined in this report focuses on a comparative analysis between additive manufactured H13 tool steel and heat-treated additive manufactured (AM) H13 tool steel, with the aim of determining the suitability of heat-treated AM tool steel for broader application scenarios.
