AM Feedstock: Part 1 - Metal Powder Characterization and Specification

July 15, 2021

About the Webinar:

Part 1 of the AM Feedstock webinar covers the fundamental concepts of metal powder characterization and specification including:

  • An overview of powder characterization techniques used in AM
  • Highlights of gaps in powder testing standards and ongoing research activities
  • An overview of AM powder feedstock specifications
  • Details on the development of new test methods on flowability and spreadability in AM

Learning Outcomes

  • An understanding of commonly used powder characterization techniques used in AM
  • An appreciation of how AM powder feedstock is typically specified


Dr Steven Hall, Senior Research Engineer in the Advanced Materials Processing group at MTC, has been involved in manufacturing R&D for over 10 years. Joining MTC in 2015, Steven has focused on the development of powder-based manufacturing processes such as Additive Manufacturing (AM), for a range of industrial sectors including aerospace and defense. Steven has technically lead and managed innovation projects on powder-process-part development, novel feedstock characterization methods, and standards development as part of ASTM’s AM Centre of Excellence (CoE) R&D projects. Steven is currently leading the development of draft standards on quality assessment guidelines for powder characterization, and understanding how to define and measure the spreadability of powders used in AM processes.

AM CoE by the Numbers

With decades of experience in additive manufacturing, our team of experts is integral to our work. With team members located throughout the Americas, Europe, and Asia, the AM CoE is able to provide agile support for global initiatives.
