This article is focused on Directed Energy Deposition (DED) Technology, a key branch of AM that's gaining popularity in recent years. It presents an overview of DED technology, process steps, key process variables and their effect on part quality, raw materials used in DED processes and post...
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...
Below is a simple illustration of Sciaky’s Directed Energy Deposition method. With our DED technology (calledElectron Beam Additive Manufacturingor EBAM®), we feed metallic wire directly into an electron beam to create metal preforms out of a molten substrate pool. Once the part reaches near-...
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...

Using the additive manufacturing directed energy deposition (AM-DED) module in the Ansys Additive Suite, the printability of a nickel-based turbine blade component was investigated and the results were compared with a physical part. Figure 1. Meltio Technology - Printhead inside of M450 ...
Directed energy deposition-arc(DED-Arc)technology has the advantages of simple equipment,low manufacturing cost and high deposition rate,while the use of DED-Arc has problems of microstructure inhomogeneity,position dependence of macroscopic mechanical properties and anisotropy.Therefore,it is necessary to...
Laser directed energy deposition (LDED) technology provides an opportunity to break through the size and geometry limitations of bulk metallic glasses (BMGs). However, the microcracks, induced by the huge thermal stress during the LDED process, seriously damage the mechanical properties of deposited ...
