Additive manufacturing-assisted casting of 3D micro-architected heat sinks

Research output: Contribution to journalArticlepeer-review

Abstract

The rapid advancement in electronic devices has heightened thermal management challenges. This study presents the fabrication of 3D micro-architected heatsinks using additive manufacturing (AM) assisted casting. This approach merges AM's design flexibility with casting's cost-effectiveness and versatility, enabling complex heatsink geometries. The fabricated heatsinks were analyzed using scanning electron microscopy and computed tomography. The thermal behavior of the heatsinks was assessed in forced convection conditions. A temperature drop at the base ranging from 5% to 13% was measured.
