Directed Energy Deposition

Directed energy deposition, an important metal additive manufacturing process, is now covered in an ASTM International standard. The standard (soon to be published as F3187, Guide for Directed Energy Deposition of Metals) was developed by ASTM International Committee F42 on Additive Manufacturing Technologies.

In the directed energy deposition process, focused thermal energy is used to fuse materials by melting as they are they are being deposited. DED is used in industry for repair, rapid prototyping and low volume part fabrication. Industries using DED in production applications include aerospace, defense, and petrochemical. 

“This guide provides users of directed energy deposition technology information useful for the specification or use of the technology. It includes applications, DED system set-up, machine operation, documentation, work practices, and system and process monitoring,” says ASTM member Richard Grylls of SLM Solutions NA Inc.

DED technology comes in several forms. These include machines using laser beams and blown powder, electron beams and wire, and arc plasma and wire.
