What are Directed-Energy Systems?
Directed-Energy Systems for additive manufacturing focus thermal energy, typically from a laser or electron beam or a plasma arc, to fuse materials by melting as they are being deposited onto a substrate. Material typically feeds from powder or wire.
What is Powder-Fed?
Powder-Fed DED systems (i.e., Laser Metal Deposition (LMD) and Laser Engineered Net Shaping (LENS)) deliver powder through a nozzle to then be melted by a laser or electron beam, or a plasma arc.
