Direct Energy Deposition is increasingly replacing conventional methods for the repair of parts. Since it is an automated process, DED provides high levels of control and repeatability, which is particularly important for complex and precise parts. The process is already used for applications such as...
Directed Energy Deposition (DED) is a metal additive manufacturing process where an energy source – usually an Electron Beam, Laser or Arc (PAW, GTAW, TIG) – is directed toward a plate or other substrate material where it impinges with wire or powder feedstock material and melts, leaving de...

Find a 3D Printing service Directed Energy Deposition The Directed Energy Deposition (DED) 3D printing technology, also known as Direct Energy Deposition, creates parts by directly me...
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...
Directed energy deposition (DED) process is an additive manufacturing technology that involves feeding metal powder through a nozzle onto the substrate whilst simultaneously fusing it with a laser. This paper presents a study on process parameters optimization for achieving better hardness for deposition ...
Directed energy depositionCr depletionHigh-temperature corrosionIn this work, a fast optical spectrometer was used to monitor the Directed Energy Deposition (DED) process, during the deposition of Alloy 718 samples with different laser power, thus different energy inputs into the material.
