Influence of high powder flow dynamics on the efficiency of laser-directed energy deposition

The behavior of powder streams under high-flow conditions remains not fully explored, despite its critical importance for enhancing productivity in modern laser-directed energy deposition (L-DED) processes. This study visualizes powder flow dynamics using area illumination and high-speed imaging. Th...
