Investigating the anisotropic effects on machining behavior and performance of as-built selective laser melting processed Ti6Al4V alloy

This study examines how the natural anisotropy of as-build Ti6Al4V, fabricated using Selective Laser Melting, affects its machining behavior, specifically focusing on hardness and microstructure behavior. Milling experiments were carried out to understand how the anisotropy material responds to machining and its impact on the final surface finish. Advanced techniques, including FE-SEM, were employed to analyze the microstructure, revealing intricate microstructural details. EDS was used to assess the elemental composition of the materials. Additionally, hardness testing was conducted to evaluate the mechanical properties, highlighting the effects of anisotropic behavior on the alloy’s performance characteristics. The findings underscore the significance of understanding anisotropy in Ti6Al4V, as it profoundly influences the as-build Ti6Al4V response to machining and overall functionality. By understanding these anisotropic effects, this research emphasizes the need to account for such variations when designing and manufacturing parts with SLM technology. Understanding these anisotropic effects is critical for optimizing SLM part design and manufacturing processes, leading to greater efficiency and improved performance, particularly in biomedical applications.
