Directed energy deposition (DED) additive manufacturing: Physical characteristics, defects, challenges and applications
David Svetlizky,Mitun Das,Baolong Zheng,Alexandra L. Vyatskikh,Susmita Bose,Amit Bandyopadhyay,Julie M. Schoenung,Enrique J. Lavernia,Noam Eliaz +8 more
TL;DR: 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 material, layer by layer as discussed by the authors.
