43. Golf Ball
This scanning electron image shows a 60 micron Stainless Steel powder particle that resulted as a by-product from the direct metal laser sintering (DMLS) process. During the DMLS process, powder particles are ejected from the melt pool similar to the process that produces spatter in welding. The study of DMLS spatter characteristics is significant because it has potentially different morphology and properties than the original powder feedstock which is seen in the margins of the image. The unique formation of oxide islands on the surface of the ejecta particle give it an appearance similar to that of a golf ball and this phenomenon has yet to be characterized in published literature.
Studying this formation is necessary to understand the properties of products fabricated using DMLS and the potential recyclability or reuse of feedstock powders for powder based metal additive manufacturing processes. Developing a comprehensive understanding of these factors would impact the acceptance of DMLS within the medical, automotive and aerospace industries.
