Abstract
Powder reuse is an integral part of laser powder bed fusion (LPBF) additive manufacturing (AM). A mathematical series expression is proposed to quantify powder damage in powder reuse in LPBF AM considering various mixing ratios. A term called damage factor has been introduced and an example of an application of the series is demonstrated. Finally, a short experimental design has been suggested to verify the model.Citation
