A method for producing polyamide particles may include: mixing a mixture comprising a polyamide, a carrier fluid that is immiscible with the polyamide, and nanoparticles at a temperature greater than a melting point or softening temperature of the polyamide and at a shear rate sufficiently high to disperse the polyamide in the carrier fluid; cooling the mixture to below the melting point or softening temperature of the polyamide to form solidified particles comprising polyamide particles having a circularity of 0.90 or greater and that comprise the polyamide and the nanoparticles associated with an outer surface of the polyamide particles; and separating the solidified particles from the carrier fluid.

Polyamide particles and methods of production and uses thereof

A particle and a method for producing the same is disclosed. For example, the particle includes a polymer resin that is compatible with a three-dimensional (3D) printing process to print a three-dimensional (3D) object and a marking additive that allows selective portions of the 3D object to change color when exposed to a light, wherein the marking additive is added to approximately 0.01 to 25.00 weight percent (wt %).

Particles comprising marking additives for selective laser sintering-based additive manufacturing systems

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.
