NOVELTY - Selective laser sintering process involves: 1) depositing carbon nanomaterial-graft-polyolefin (CNM-g-polyolefin) particles optionally in combination with other thermoplastic polymer particles on a surface, where the CNM-g-polyolefin particles comprise a polyolefin grafted to a carbon nanomaterial; and 2) then exposing at least a portion of the CNM-g-polyolefin particles to a laser, for fusing the polymer particles and forming a consolidated body by selective laser sintering. USE - Selective laser sintering is used for forming highly spherical particles comprising CNM-g-polyolefin. ADVANTAGE - The process having entirely different structural and mechanical tolerances, enables preparing highly spherical particles comprising CNM-g-polyolefin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method used for forming highly spherical CNM-g-polyolefin particles, which involves: i) mixing a mixture comprising: (a) CNM-g-polyolefin, (b) a carrier fluid that is immiscible with the polyolefin of CNM-g-polyolefin, optionally (c) a thermoplastic polymer not grafted to CNM, and optionally (d) an emulsion stabilizer, at temperature more than the melting point or softening temperature of polyolefin of CNM-g-polyolefin and the thermoplastic polymer, when included, and at a shear rate sufficiently high to disperse the CNM-g-polyolefin in the carrier fluid; ii) cooling the mixture to below the melting point or softening temperature, to form CNM-g-polyolefin particles; and iii) separating the CNM-g-polyolefin particles from the carrier fluid.
