Laser powder bed fusion (LPBF) has aided the design of complex geometries with different class of alloys for various applications. However processing different types of alloys with LPBF poses distinct problems. Alloy chemistry, processing parameters in LPBF, component design needs to be tailored to obtain optimum performance of the component (such as targeted thermal/mechanical properties) manufactured with LPBF. In this study, LPBF of Cu alloys is explored for heat flux application which involves complex designs. This research is primarily focused on improving the LPBF processability of pure copper and copper alloys. Different approaches such as coating copper powder, alloying copper, powder blending technique to incorporate secondary materials will be explored to enhance the copper processability in LPBF. Later, LPBF process parameter optimization will be done on novel alloy powders. Effect of LPBF process parameters on materials properties, resulting defects, different type of geometries is analysed. Along with high thermal conductivity, copper alloys needs to possess sufficient mechanical strength for high temperature application. Improved mechanical strength can help to make more thin and complex structures to reduce weight and escalate the performance. In the next step, thermal and mechanical properties of the LPBF processed copper alloys will be investigated.
