Novel Magnesium Nanocomposite for Wire-Arc Directed Energy Deposition. [PDF]

Materials (Basel)
Magnesium alloys play an essential role in metallic lightweight construction for modern mobility applications due to their low density, excellent specific strength, and very good castability. For some years now, degradable implants have also been made from magnesium alloys, which, thanks to this special functionality, save patients a second surgery for

IMProVing directed energy deposition [PDF]

PhotonicsViews, 2021
AbstractDirected energy deposition (DED) is a powerful additive manufacturing technique that combines a high degree of freedom in design with relatively high deposition rates that can increase throughput. DED structures are created by repeatedly depositing weld beads from powder or wire feedstock, which also makes it an attractive technique for hybrid ...
