Abstract: A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75° C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.

Abstract: Various methods and devices transfer test patches of marking material from a marking device of a printing apparatus to a transfer surface of the printing apparatus, optically measure the density of the test patches on the transfer surface using an optical sensor of the printing apparatus, and measure the electrostatic differences in charge of the transfer surface as the test patches on the transfer surface move by an electrostatic sensor of the printing apparatus. Such methods and devices adjust settings of the marking device based on output from the electrostatic sensor alone, or based on a combination of the output from the optical sensor and converted output from the electrostatic sensor.

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: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may lead to excessive porosity following consolidation. Excessive porosity may be detrimental for performance applications requiring high mechanical strength. A carboxylic acid-based sintering aid, particularly a metal carboxylate, may decrease porosity of consolidated parts following sintering without substantially increasing blocking in a powder bed. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a carboxylic acid-based sintering aid admixed with a thermoplastic polymer, and a plurality of nanoparticles disposed upon an outer surface of the thermoplastic particulates.
