Jonathan Pegues, a researcher in Sandia’s Coatings & Additive Manufacturing department, was approved to be the first formally approved Sandia outbound Faculty Loan joint appointee. Pegues’ joint appointment is an agreement between Sandia and Auburn University’s (AU) National Center for Additive Manufacturing Excellence (NCAME). The NCAME is a collaborative effort among AU, NASA, ASTM International and EWI that works to close the standardization and workforce development gaps in additive manufacturing through effective coordination of industry, government, academia, non-profit organizations, and ASTM committees.
Pegues is not new to the standards arena. He currently serves as Secretary for the ASTM sub-committee on Additive Manufacturing Applications. In 2020, he collaborated with ASTM International’s additive manufacturing technologies committee to create a proposed standard to rapidly assess the quality of laser beam powder bed fusion (LB-PBF) processes. The proposed standard aims to use off-the-shelf tools to quickly generate qualitative data related to dimensional accuracy and material strength, both of which serve as build health indicators of the machine and the parts.
Pegues said the standard he worked on previously for the production of LB-PBF parts for structural applications could potentially be extended to other additive manufacturing techniques. He added, “In this joint appointment position, I’m looking forward to working closely with graduate students to address safety and reliability concerns for fatigue critical additive manufactured parts.”
