IMProVing directed energy deposition [PDF]
PhotonicsViews, 2021 AbstractDirected energy deposition (DED) is a powerful additive manufacturing technique that combines a high degree of freedom in design with relatively high deposition rates that can increase throughput. DED structures are created by repeatedly depositing weld beads from powder or wire feedstock, which also makes it an attractive technique for hybrid ...
