Mechanical/ Materials Engineer - Characterization and mixing of metal powders in additive manufacturing -3237

Project Title: Characterization and mixing of metal powders in additive manufacturing PREP0003237
 

Project Plan: Understanding how metal powders perform in additive manufacturing (AM) systems and how those powders change over time is critical to industry practitioners making decisions about the usability and re-usability of metal powders. NIST is conducting research to characterize the flow, spreading, and mixing of metal AM powders. This project includes the operation and improvement of a powder spreading testbed to conduct experiments exploring the correlations between powder properties and spreading performance and generating data to help improve and validate models/simulations of the powder spreading process. The project also includes investigating potential correlations between heterogeneity in powder AM feedstocks with heterogeneity of local properties in
the resultant parts, which will impact guidance on mixing re-used powders with virgin powder feedstocks.
 

The work will entail:

Key responsibilities will include but are not limited to:
 

• Developing and improving operating procedures for the NIST powder spreading testbed
• Operating the NIST powder spreading testbed to conduct various experiments in powder spreading,
• Developing designs of experiments for the NIST powder spreading testbed,
• Developing experiments to correlate heterogeneity in powder feedstock with heterogeneity in local properties of built AM parts.
• Preparing AM feedstock samples and AM parts for measurement and analysis, including metallography and optical microscopy.
   

Qualifications
 

• A Master’s degree in Mechanical Engineering, Metallurgy, Materials Science, or a related field,
• Familiarity with laser powder bed fusion additive manufacturing,
• Familiarity with measurement of metal powder feedstocks for additive manufacturing,
• Ability to work well in a team,
• Strong oral and written communication skills.
