Production of Single Tracks of Ti-6Al-4V by Directed …

Here, F is the powder feed density, and G is the powder feeding rate (g/s). Figure 5 demonstrates the variation of deposited layer height as a function of specific energy density. As can be seen, the height of single tracks increased by increasing the specific energy density, which can be related to the higher heat input at the higher laser energy density.
