Directed Energy Deposition

Share

Directed energy deposition (DED) builds up material layer-by-layer. A nozzle deposits and melts material onto a target with a directed beam of energy, such as a laser or an electron beam. The material cools and forms a solid part. The National Institute of Standards and Technology (NIST) Additive Manufacturing (AM) Program implements various directed energy deposition techniques for AM. Learn more about our directed energy deposition work by exploring the content below. If you would like guidance on additive manufacturing efforts or a chance to use our resources, please explore our various research opportunities and/or contact us.
