| Abstract Scope |
Multi-Material Laser Powder Bed Fusion (MM-LPBF) represents a transformative advancement in additive manufacturing, enabling the fabrication of high-resolution, functionally graded components with spatially tailored material properties. By integrating selective powder deposition (SPD) within the conventional LPBF framework, MM-LPBF allows for precise control over composition and microstructure, opening new possibilities for engineering applications that demand heterogeneous material properties within a single build.
This talk provides a comprehensive review of the MM-LPBF process, focusing on the fundamental principles, key processing parameters, and their impact on material compatibility, process-induced defects, and interfacial formation mechanisms. The discussion centers on the process-structure-property relationship, addressing the challenges of maintaining metallurgical integrity across dissimilar material interfaces. |
