A Study of Different Deposition Strategies in Direct Energy Deposition (DED) Processes

Procedia Manufacturing, 2020
The stepover of adjacent deposition lines (or beads), when stacking layers to build a 3D-solid shape, is found to be of great importance to minimize voidage and so, improving density of parts produced by the Directed Energy Deposition (DED) process ...
