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 de...
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...

A directed energy weapon refers to a type of system that disrupts or damages lone or multiple targets without the use of a projectile. Unlike existing systems that jam or confuse incoming threats, the Thales RFDEW system, known as RapidDestroyer, is a hard-kill mechanism. The syste...
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...
Directivity is important because it helps indicate how much sound will be directed towards a specific area compared to all the sound energy being generated by a source. If you have a limited amount of sound energy available (like that produced by the human voice), you can increase the ...
