| Abstract Scope |
Powder recycling in additive manufacturing is often seen as good industrial practice, offering both economic and environmental benefits because of waste reduction. It enables excess powder to be reused for subsequent build, once mixed with the virgin or as-received powder.
However, as more parts are made and more recovered powder is added, the ratio of virgin to recovered powder may change. It is therefore important to track these changes to ensure that the resulting parts made from recovered powders still perform identically to the parts made from virgin powder.
In this study both virgin and recovered powder and their corresponding build parts are characterized as a function of build number using a range of conventional characterization techniques including X-ray fluorescence (XRF), X-ray diffraction (XRD) and supplemented with mechanical testing. These have shown to have the necessary sensitivity to detect minor variations of consequence in parts and recovered powder. |
