Though "directed energy deposition" is the standard terminology for this additive manufacturing process, there are many categories within DED, along with many different process names. The number of publications shown in Fig. 28.1 is most likely an underestimation of the research in the field, as many researchers do not use the term
Direct Energy Deposition (DED) is a family of Additive Manufacturing technologies that uses a directed heat source to melt a feedstock material. DED of metals allows additive manufacturing of large scale metallic components at a much higher deposition rate compared to other AM technologies, such as Powder Bed Fusion (PBF).
Direct Energy Deposition. Con il termine Directed Energy Deposition, o reviato DED (Deposizione ad energia diretta) si intende un gruppo di tecnologie di Stampa 3D a metallo che utilizza un materiale sotto forma di polvere o filo, che viene depositato e fuso localmente tramite una fonte ad alta densità di energia (che può essere
Arc-Directed Energy Deposition 2. Laser Directed Energy Deposition . While laser powder bed fusion (LPBF) is better for small to medium-sized components with high detail and internal features, laser-directed energy deposition (LDED) combines a material feed system to place the powder onto the exact spot where the laser will melt the material.
