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.

Comparative insights into microstructure and magnetism of Ni-Mn-Sn Heusler alloys manufactured by electron beam and laser beam powder bed fusion

Additive Manufacturing Letters, 2023
Powder bed fusion (PBF) is a promising but challenging method for additive manufacturing of magnetocaloric Ni-Mn-Sn Heusler alloys, due to the material's inherent brittleness. To produce crack-free near-net-shape parts from prealloyed gas atomized 47.2Ni-
