Directed energy deposition (DED) is based on a laser process in which a laser beam generates a melt pool on a substrate. An additional metallic powder material is transported to the melt pool, where it becomes molten. Due to a feed movement, the molten material cools down and welding tracks are formed.
By placing weld tracks side by side and on top of one another, a buildup can be obtained. You can then generate three-dimensional structures by depositing one layer or track at the top of another already welded layer or track
