Abstract: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Inorganic nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may be undesirable to incorporate in some printed objects. Polymer nanoparticles may be substituted for inorganic nanoparticles in some instances to address this difficulty and provide other advantages. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a thermoplastic polymer and a plurality of polymer nanoparticles disposed upon an outer surface of the thermoplastic particulates, the polymer nanoparticles comprising a crosslinked fluorinated polymer.

Abstract: A mixing process and system for mixing fluid such as a latex can include a first fluid and a second fluid that are combined to form, for example, a latex precursor. A plurality of magnetic particles are dispensed within the precursor. The precursor is dispensed within a mixing zone that may include a mixing tube. Two or more opposing electromagnets are activated out of phase (i.e., out of sync) to affect a travel path of the magnetic particles to form a turbulence within the precursor to provide an effective mixing of the precursor to form a material such as latex. The magnetic particles may be removed from the material, for example by filtering, or may remain within the material during use.
