Powder Reuse Cycles in Electron Beam Powder Bed Fusion—Variation of Powder Characteristics [PDF]
Materials, 2021 A path to lowering the economic barrier associated with the high cost of metal additively manufactured components is to reduce the waste via powder reuse (powder cycled back into the process) and recycling (powder chemically, physically, or thermally processed to recover the original properties) strategies.

On the Reuse of SLS Polyamide 12 Powder
Materials, 2022 In the Selective Laser Sintering (SLS) technique, the great majority of the powder involved is not included in the final printed parts, being just used as a support material. However, the quality of this powder is negatively affected during the process since it is subjected to high temperatures (close to its melting temperature) during a long time, i.e.
