Abstract: Colored particulate blends may be produced by combining thermoplastic polymer particulates that differ from one another in color. Such colored particulate blends may comprise: a first plurality of thermoplastic polymer particulates comprising a first thermoplastic polymer and a first colorant blended with the first thermoplastic polymer in an interior of the thermoplastic polymer particulates, and a second plurality of thermoplastic polymer particulates comprising a second thermoplastic polymer and, optionally, a second colorant blended with the second thermoplastic polymer in an interior of the thermoplastic polymer particulates. The first plurality of thermoplastic polymer particulates has a first color, and the second plurality of thermoplastic polymer particulates has a second color different than the first color, and the second colorant, if present, is different than the first colorant. The colored particulate blends are visually homogenous and appear as a single color different than the first color and the second color.

Abstract: A method for producing metal or metal alloy particles may include: mixing a mixture comprising: (a) a metal or a metal alloy, (b) a carrier fluid, and optionally (c) an emulsion stabilizer at a temperature at or greater than a melting point of the metal or the metal alloy to create a dispersion of molten droplets of the metal or the metal alloy dispersed in the carrier fluid; cooling the mixture to below the melting point of the metal or the metal alloy to form metal or metal alloy particles; and separating the metal or metal alloy particles from the carrier fluid, wherein the metal or metal alloy particles comprise the metal or the metal alloy and the emulsion stabilizer, if included.
