2024年2月20日 · 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.

2021年10月1日 · 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...

2024年5月29日 · Directed Energy Deposition (DED) forms 3D objects by melting material as it is deposited using focused thermal energy, such as a laser, electron beam, or plasma arc. DED is one of the seven categories of additive manufacturing processes, which uses 3D data to build objects layer by layer instead of using subtractive manufacturing technologies.

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 deposited material on the substrate.

Metal additive manufacturing technologies, such as powder bed fusion process, directed energy deposition (DED) process, sheet lamination process, etc., are one of promising flexible manufacturing technologies due to direct fabrication characteristics of a metallic freeform with a three-dimensional shape from computer aided design data.

2023年4月27日 · This 3D printing process melts metal powder or wire as it's deposited to repair or manufacture a wide range of parts.

2023年3月2日 · Directed Energy Deposition (DED) is a way to make things out of metal. It uses a special tool, like a laser or an electron beam, to melt metal powder or wire onto a surface. This process can make really cool three-dimensional objects that are strong and very accurate in size. DED is one of many ways to make things out of metal.

Directed Energy Deposition (DED) is a category of metal additive manufacturing (AM) that utilizes robotic welding processes to print at high deposition rates but with relatively low resolution. DED systems use an electric arc, plasma, laser or electron beam to melt metal feedstock (wire or powder) into a molten deposit pool.

2 天之前 · The term Direct Energy Deposition (DED) basically refers to a form of metal 3D printing, wherein the remelting of metal feedstock onto a substrate is done with a focused energy source such as laser or electron beam. Indeed, such a process is considered extremely flexible and therefore parts can be highly customized, repaired, or modified.

Directed Energy Deposition (DED) is a manufacturing process that is opening exciting opportunities for metal component creation and repair. In this blog, we have created an overview of what DED is & where wire arc additive manufacturing (WAAM) fits into the picture.
