| Abstract Scope |
Additive manufacturing is a promising technology used in many industries today. With its flexibility in parameter and material control, it is a tool for advanced production. Exploring lunar resources has also become an area of growing interest in space engineering. This study investigates the effects of lunar dust on the microstructural and mechanical properties of 3D printed stainless steel using laser- wire directed energy deposition. Single-track line samples were created under controlled printing parameters, followed by a comparison between printed steel with and without the inclusion of regolith powder. Microstructural changes were analyzed through scanning electron microscopy and optical microscopy, while mechanical properties such as tensile strength and hardness were evaluated using standardized testing methods. By studying the properties of 3D printed stainless steel, this research aims to offer an understanding of how lunar dust influences its performance, contributing to the development for future lunar missions and space exploration. |
