Directed energy deposition is a broadly employed 3D printing technique for producing gradient-structured metals and alloys. This process utilizes an electric arc or laser to melt metals in the form of wires or powders [103–106].
Directed energy deposition (DED) processes enable the creation of parts by melting material as it is being deposited. Although this basic approach can work for polymers, ceramics, and metal matrix composites, it is predominantly used for metal powders.
The present study examines the effect of varying laser incidence angles on textural, microstructural, and geometric characteristics of directed energy deposition (DED) processed materials,
Abstract: Enhancing the geometric accuracy of additive manufacturing (AM) processes remains a vital challenge, particularly in the context of directed energy deposition (DED). This paper investigates the use of a laser line scanner for real-time layer height estimation during the DED process. The proposed system offers a method for 3D reconstruction and

6 · The most prominent method for the creation of large-scale metallic parts is directed energy deposition (DED), in which lasers or other energy sources are used to melt a powder stream or wire feedstock to deposit the material layer by layer on the build platform. Because the specifics of the DED setup can have major effects on the quality of

Directed energy deposition (DED) AM is a process that deposits powder or wire material layer-by-layer using a high temperature source (e.g. laser, arc, electron beam, etc.) [1]. DED AM can build with multiple materials simultaneously to enable creation of
ER5356, ER2319 and Zn wires were synchronously fed using a multi-wire gas metal arc directed energy deposition (DED) system. This allowed the successfully fabrication of Al-6.0Zn-2.5Mg-1.5Cu alloy. The microstructure and mechanical properties of the fabricated parts were studied. It is shown that the main precipitated phases are η and
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 or wire source materials.
