Please be advised that a New Work Item Proposal has been loaded to the BSI Standards Development Portal for comment.

Any comments received will be submitted to the national committee AMT/8 – “Additive manufacturing” for consideration when deciding the UK response to the associated Standards Development Organisation.

Proposal: ISO/ASTM PWI 52922, Additive manufacturing — Design — Directed energy deposition of metals.
Please visit
Comment period end date: 26/09/2023


This document specifies the features of Directed Energy Deposition (DED) and provides detailed design recommendations. This document also provides a state-of-the-art review of design guidelines associated with the use of DED by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910.


This design guide provides guidance for different DED technologies by providing information about typical characteristics of DED parts and features, insights into the process-based causes of these characteristics, and an understanding of process capabilities and limitations. The information and understanding should provide guidance to designers that they can exploit to take advantage of DED capabilities, design around limitations, and avoid process disadvantages. This document extends ISO/ASTM 52910, the general design guide, and complements powder bed fusion design guides for metal and polymer materials (ISO/ASTM 52911-1 and -2), as well as other process-specific design guides that are under development. In addition, it specializes and builds upon the general DED descriptions in Guide F3187.
