| Abstract Scope |
Laser Powder Bed Fusion (LPBF) has demonstrated effectiveness for single-material components but faces challenges with multi-material systems due to dissimilar material compatibility, interfacial bonding, and thermal mismatch. This study explores Multi-Material LPBF (MM-LPBF) to fabricate a 3D architecture combining a stainless-steel lattice with copper. The structure aims to unify stainless steel’s mechanical strength and copper’s thermal conductivity to improve performance in demanding applications. A 3D cube model was designed in Solid Edge and printed using MM-LPBF. ANSYS simulations evaluated thermal distribution and mechanical deformation under thermal stress, with focus on the stainless steel–copper interface. The outcomes of the study provide insight into interfacial behavior and highlights strategies for integrating dissimilar metals using MM-LPBF, contributing to structural and thermal optimization in multi-material additive manufacturing. |
