Beschreibung
Zusammenfassung:	A powder composition for use in additive manufacturing, related metal-based particles, related methods and related consolidated part. The composition consisting of metal-based particles and a remainder representing at most 10 wt % of a total weight of the composition, which can be at least one of a ceramic, a lubricant and a binder. The metal-based particles are highly spherical and can be considered fines-free. More particularly, less than 8,000,000 of the metal-based particles per gram of the metal-based particles have a diameter smaller than or equal to 15 μm; and the metal-based particles have at least one of an average aspect ratio greater than or equal to 0.95; an average roundness greater than or equal to 0.95; and an average Krumbein sphericity greater than or equal to 0.95.
