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...

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.

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.

2023年5月10日 · Direct energy deposition (DED), also referred to as directed energy deposition, is a particular approach to additive manufacturing (3D printing). It directs an energy source at a spot on the source material to make a small amount of melt and then adds feed material to this melt in order to deposit new material onto the component.

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...

2022年5月18日 · 定向能量沉积（DED）是增材制造（AM）工艺的一个分支，在该工艺中，粉末或金属丝形式的原料被输送到同时聚焦激光束、电子束或等离子/电弧等能量源的基板上，从而形成一个小熔池并逐层连续沉积材料。 与其他AM工艺相比，DED具有一些独特的优势，例如特定位置的沉积和修复、合金设计和复杂形状的三维打印。 在此，对近年来的进展以及在DED过程中控制激光与材料相互作用的主要方面、熔池热行为、先进的原位监测和相互作用机制进行了评述。 还 …

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.

2023年11月28日 · Directed energy deposition (DED) is a major category of processes used for additive manufacturing of metallic materials. Instead of using a powder layer, like the PBF processes, the material is deposited directly at the melt pool created by the energy source.

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.

2023年10月18日 · Directed energy deposition (DED) is an additive manufacturing process that melts a feedstock material during deposition with a focused thermal energy source, which is typically a laser, electron beam, gas metal arc, or a plasma arc [1].
