Quality Additive Manufacturing Focus of Publication by RJLG’s Amber Dalley, Stephen Kennedy & Greg Kotyk

The quality of powder feedstock can impact the quality of the parts built during the additive manufacturing process. Products may be contaminated by their environment during manufacturing, handling, or even during the building process. Because additive manufacturing is prevalent in high-performance industries, such as aerospace, medical, power generation and the military, it is crucial to identify potential particle contaminants. A recent article published by RJLG’s Amber Dalley, Stephen Kennedy & Greg Kotyk describe three methods to identify and characterize powder feedstock. These methods include computer-controlled scanning electron microscopy (CCSEM), energy-dispersive spectroscopy (EDS) and heavy liquid separation (HLS).
