10. Sept. 2019 · Der 3D-Druck durch Abscheidung von Material unter konzentrierter Energie, auch bekannt als DED (Directed Energy Deposition), ist ein komplexes Verfahren, das verschiedene Technologien vereint und zu den Verfahren im 3D-Metalldruck gehört.
The DED process is defined as “additive manufacturing process in which focused thermal energy is used to fuse materials by melting as they are being deposited” by ISO/ASTM 52900 standard [ 7 ]. The principle of the DED process is illustrated in Figs. 1 and 2 [ 24, 57 ].

20. Feb. 2024 · Directed Energy Deposition (DED) — sometimes just Direct Energy Deposition — is a metal 3D printing technology offering key advantages in larger metal part creation. Similar to other metal 3D printing methods, DED builds parts by sintering metal in layers to form a three-dimensional structure.
Mit der 3D-Printing-Technologie der gerichteten Energiedeposition (Directed Energy Deposition, DED), auch bekannt als direkte Energiedeposition (Direct Energy Deposition), werden Teile durch direktes Schmelzen von Materialien und schichtweises Ablegen auf dem Werkstück erzeugt.

Directed energy deposition (DED) is an AM process that can print parts by melting material as it is being deposited [50]. This process uses a focused heat source (laser or electron beam) to melt the deposited material.
1. Okt. 2021 · Directed energy deposition (DED) is a branch of additive manufacturing (AM) processes in which a feedstock material in the form of powder or wire is delivered to a substrate on which an energy source such as laser beam, electron beam, or plasma/electric arc is simultaneously focused, thus forming a small melt pool and continuously depositing mat...
