New Specification for Additive Manufacturing -- Wire for Directed Energy Deposition (DED) Processes in Additive Manufacturing

1. Scope

The promotion of knowledge, stimulation of research and implementation of technology through the development of standards for additive manufacturing technologies. The work of this Committee will be coordinated with other ASTM technical committees and other national and international organizations having mutual or related interests.

Keywords

12.1 additive manufacturing; directed energy deposition; wire

Rationale

Directed energy deposition (DED) additive manufacturing (AM) can enable reductions in cost, lead time, and material waste compared to other manufacturing techniques. It achieves this through the ability to create parts, including near-net-shaped parts, by melting and depositing material in layers, with high deposition rates. Reductions in cost, lead time, and material waste have significant impact on high-value manufactured parts. Different heat sources can be used to melt the material including arc, electron beam, and laser. Both wire and powder can be used as material. One challenge facing industrialization of DED AM is a lack of related standards. To date, welding wire specifications are used for wire for DED AM, but these may not be suitable. It is the intention of this specification to outline requirements for composition, dimensions, and condition of wire for high-value DED AM in addition to marking, packaging, handling, and storage of the wire. Recommendations for testing methods are also listed. This specification defines different DED AM processes and specifies different product types that can be used for the processes. This specification aims to enhance the understanding of wire for DED AM and wire manufacturing and improve communication between customers and manufacturers or suppliers of materials. Ti6Al4V is the most extensively researched material for DED AM. Materials that can be deposited using DED AM include, but are not limited to, Ti6Al4V.

The title and scope are in draft form and are under development within this ASTM Committee.
