Thermal conductivity of metal powder for use in additive manufacturing of metals

The researcher examines the thermal conductivity of metal powders for additive manufacturing of metals. The hypothesis tests whether accurate measurement and optimization of these properties can improve heat management and part quality in metal additive manufacturing (3D Printing). The laser flash method measures transient thermal diffusivity (Heat transfer over time) of powders such as titanium, Inconel, and stainless steel 316L. Simulations can then develop optimized compositions with enhanced effective thermal conductivity. This approach reduces defects such as porosity and cracking in laser powder bed fusion. It enables stronger, more reliable components for biomedical applications, including custom medical implants.
