Characterization of Powder and the Effects of Powder Reuse in Selective Laser Melting
2023The ability to reuse feedstock in additive manufacturing powder bed processes is vital for cost control and widespread adoption of the technology. This requires an understanding of the effects of thermal cycling in the ambient conditions an additive machine has on the physical, chemical, and microstructural properties of the powder.

The impact of powder reuse on powder characteristics of laser powder bed fusion TA 15 alloy
Rapid Prototyping JournalPurpose Most research on Laser powder bed fusion (L-PBF) has focused on using virgin metal powders. Meanwhile, the microstructure and mechanical properties of annealed L-PBF components produced with reused powders, particularly titanium alloys, have been less thoroughly investigated.

Reuse of Byproduct Alumina Composite Powder from Hydrogen Production Process
Advanced Materials Research, 2015Water molecule reacts with aluminium when it is immersed in water, which plays a vital role in hydrogen generation process. This process which uses sodium hydroxide as catalyst produces a byproduct alumina and some other scarce ingredients. This byproduct is mentioned as alumina composite powder (ACP).
