Additively manufactured copper surfaces with porous microfeatures for enhanced pool boiling performance

T. Bregar, A. Hadžić, J. Robinson, M. Zupančič, I. Golobič

International Journal of Thermal Sciences

This study evaluates pool boiling on additively manufactured copper surfaces with various microstructures, using distilled water under saturated atmospheric conditions. Initially, heat-treated and untreated samples were compared to assess thermal conductivity effects. Heat-treated samples, despite higher thermal conductivity, generally showed lower heat transfer coefficients (HTC) due to smoother surfaces and fewer active nucleation sites. Further testing involved heat-treated surfaces with channels, tunnels, chimneys, and pillars of varying heights, benchmarked against a flat surface.

Tunable stiffness and crashworthiness of selective laser melted AlSi10Mg sinusoidal auxetic structures

M. Singh, A. Arjunan, A. Baroutaji, C. Wanniarachchi, J. Robinson, A. Arafat, A. Vance, O. Lawal, M. Appiah

Additive Manufacturing Frontiers

This study presents the design, fabrication, and multi-objective optimisation of a novel additively manufactured aluminium sinusoidal ligament auxetic structure (SAS) using AlSi10Mg and Selective Laser Melting (SLM) achieving 99.85% density. Unlike conventional re-entrant designs, the smooth sinusoidal geometry minimises stress concentrations, enhances manufacturability, and provides tunable stiffness and crashworthiness..

Industrial Readiness of Copper AM for High-Performance Thermal Applications

J. Robinson, A. Arjunan, A. Baroutaji, M. Stanford

Proceedings of the institution of mechanical engineers, part l: journal of materials: design and applications

On-demand additive manufacturing (three-dimensional printing) offers great potential for the development of functional materials for the next generation of energy-efficient devices. In particular, novel materials suitable for efficient dissipation of localised heat fluxes and non-uniform thermal loads with superior mechanical performance are critical for the accelerated development of future automotive, aerospace and renewable energy technologies. In this regard, this study reports the laser powder bed fusion processing of high purity (>99%) copper (Cu), silver (Ag) and novel copper–silver (CuAg) alloys ready for on-demand additive manufacturing.
