Directed Energy Deposition (DED) is a 3D printing method which uses a focused energy source, such as a plasma arc, laser or electron beam to melt a material which is simultaneously deposited by a nozzle. As with other additive manufacturing processes, DED systems can be used to add material...
Other DED Methods Laser Directed Energy Deposition Machines When a Laser is the “Energy” piece of the DED equation, users can expect Laser DED Systems to achieve good feature resolution for smaller parts. They are generally simpler to operate than EB DED, use a relatively low heat input when...

2.2Directed energy deposition (DED) technique Using an intricate printing method calleddirected energy deposition, old components can often be repaired or given a material boost [16]. The structure can be managed greatly during energy deposition, producing high-quality objects. Although the nozzle isn...
Directed energy deposition (DED) has matured into an essential additive manufacturing (AM) branch. DED has been broadly implemented in the design and fabrication of novel materials. These include metals, ceramics, and composites. Successful DED operation requires a good understanding of many critical ...
Directed Energy Deposition The Directed Energy Deposition (DED) 3D printing technology, also known as Direct Energy Deposition, creates parts by directly melting materials and deposing them on the workpiece, layer by layer. This additive manufacturing technique is an essential element with metal powders...

DED parts made by a machine tool provider illustrate various ways strategic consideration of metal 3D printing or machining helps the other process.
Directed Energy Deposition (DED) processes allow additive manufacturing and repair of metallic components with generatively-designed complex geometries, and excellent compositional control. However, its applicability and adoption have been limited when compared to powder bed fusion (PBF) because several issu...
This paper proposes a strategy to optimize the design of the substrate structures used in Additive Manufacturing (AM) by Directed Energy Deposition (DED) to minimize the residual stresses induced by this fabrication process. To this end, several numerical analyses were performed to analyse different ...
