Directed Energy Deposition: Material Science in Additive Manufacturing

While Powder Bed Fusion and Binder Jetting evolved to also using metals, Directed Energy Deposition was specifically developed for this class of materials. We introduce the process principle and variations, benefits and applications of the Additive Manufacturing technology.

The Additive Manufacturing process is another process that is used for metals. While Powder Bed Fusion and Binder Jetting evolved to also using metals, Directed Energy Deposition was specifically developed for this class of materials.

What is Directed Energy Deposition?

An Additive Manufacturing process in which focused thermal energy (e.g., laser, electron beam, or plasma arc) is used to fuse materials by melting as they are being deposited (ASTM F42 Committee).

Process Principle of Directed Energy Deposition (LENS, EBAM)

We introduce the process principle of the Additive Manufacturing technology Directed Energy Deposition by looking at a schematic of a configuration with powder and a laser as well as a video of the process with two different powders.

Benefits and Applications of Directed Energy Deposition (LENS, EBAM)

In this video, we look at different configurations of the Additive Manufacturing technology Directed Energy Deposition. Furthermore, we shed light on the advantages and disadvantages of the process.

Applications of Directed Energy Deposition and Variation with Fiber Reinforced Composites

This video gives an overview of applications of the Additive Manufacturing technology Directed Energy Deposition. Additionally, we introduce a variation of the process: Composite Directed Energy Deposition.

Summary of Our Basic Series: Material Science in Additive Manufacturing

We are at the end of our video series introducing the 7 Additive Manufacturing technologies. You learned to distinguish between the different processes, tradenames and categories. By introducing the typical materials for each process, you have gained an understanding of the interaction between the process and the material. Thank you for watching!

Our next projects

We are already in the midst of preparing more content on Additive Manufacturing for you! In April, we will continue with our Advanced Series of Material Science in Additive Manufacturing, in which the focus lies on the interaction of material and process as well as the selection of suitable thermoanalytical and rheological analysis methods.

In the meantime, we categorize your questions from our Basic Video Series and are happy to share our answers to common 3D printing myths with you during the next two months.
