Directed Energy Deposition (DED) is a more complex 3D printing process, typically used to repair or add additional material to existing components. It is completely possible to fabricate parts from scratch using this technology, but it is often used for industrial applications such as repairing turbine blades or propellers that have been damaged.
Similarly to some Powder Bed Fusion (PBF) technologies (such as LPBF or EBM), Directed Energy Deposition uses a focused energy source, such as a laser or electron beam to melt the material. However, the material is melted at the same time as it’s deposited by a nozzle. In a way, the technology is at the frontier of material extrusion and powder bed fusion.
You should note that this technology is often referred to by other names such as Laser Engineered Net Shaping (LENS), Direct Metal Deposition (DMD), Electron Beam Additive Manufacturing (EBAM), etc. depending on the specific application or method.
