Abstract Scope |
Laser Powder Bed Fusion (LPBF) of Ti-alloys opens the opportunity to manufacture lightweight and complex components for medical, automotive, aerospace and space applications. The reliability of these builds needs to be very high. However, the influence of the process parameters on the melt pool dynamics and feature formation are not fully understood. Using a unique 4 laser AM machine, the Quad In-Situ and Operando powder bed Process Replicator (Quad-ISOPR), we can quantify the phenomena in the weld pool using ultra-high-speed synchrotron radiography, together with an additional coaxial high-speed optical camera and a photodiode. Here we present a process map of the melt pool dynamics for a Ti6Al4V in continuous wave and modulated mode. This process map can help optimise process parameter selection while reducing the probability of associated defects. |
