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.

3D printing of high-strength aluminium alloys
John H. Martin,Brennan Yahata,Jacob M. Hundley,Justin Mayer,Tobias A. Schaedler,Tresa M. Pollock +5 more
TL;DR: The approach to metal-based additive manufacturing is applicable to a wide range of alloys and can be implemented using a range of additive machines, and provides a foundation for broad industrial applicability, including where electron-beam melting or directed-energy-deposition techniques are used instead of selective laser melting.
