| Abstract Scope |
Powder bed fusion technology is a common additive manufacturing (AM) method, which utilizes powder as the feedstock. After fabrication, the used powder is often recycled for subsequent fabrications due to the extensive costs associated with powder atomization and handling. Therefore, there is a need for a systematic investigation to understand the effects of powder reuse on the AM part performance. This study aims to methodically inspect how the powder reuse can influence its characteristics, and consequently, the defect content, tensile, and fatigue performance of parts fabricated via laser beam powder bed fusion (LB-PBF) and plasma-atomized Ti-6Al-4V powder. In addition, parts will be fabricated in different locations on the build plate to reveal any locational dependencies of micro-/defect-structural and mechanical properties and correlate these dependencies with the powder reuse. |
