The Influence of Pores on Tensile Properties of Ti-6Al-4V by Laser Powder Bed Fusion and the Effect of Hot Isostatic Pressing

This thesis explores how metal 3D printing, specifically Laser Powder Bed Fusion (LPBF), creates complex components from titanium alloys. LPBF has advantages in prototyping and flexible design, but its parts can have pores that weaken their structure. The study investigates how different pore types affect strength and durability in LPBF-made titanium, creating models to predict their effects and using a method called Hot Isostatic Pressing (HIP) to close pores and improve part quality. The research aims to optimise production, making 3D printing faster, more reliable, and cost-effective for industrial use.
