Authors N.E. Gorji, R. O’Connor, and D. Brabazon are studying metal powders in the recently published ‘ XPS, XRD, and SEM characterization of the virgin and recycled metallic powders for 3D printing applications .’

 

Recycling continues to be an ongoing topic in the 3D printing realm as so much material is being consumed and then often discarded due to defects or other structural problems. And while obviously there is a push to re-use as much material as possible—reducing the footprint of manufacturing processes around the world—quality, performance, and functionality are key too.

 

SEM images are taken from both virgin (left) and recycled (right) powders. SEM images from the recycled powder (in 20 m and 10 m zoom) indicating the elongated particles, satellites on the surface, spatter, bonded particles and particles with irregular shapes. For this study, the authors used virgin feedstock and recycled stainless steel 316L for selective laser […]
