Optical absorber-containing thermoplastic polymer particles (OACTP particles) may be produced by methods that comprise: mixing a mixture comprising a thermoplastic polymer, a carrier fluid that is immiscible with the thermoplastic polymer, and optionally an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the thermoplastic polymer and at a shear rate sufficiently high to disperse the thermoplastic polymer in the carrier fluid; cooling the mixture to below the melting point or softening temperature of the thermoplastic polymer to form solidified particles comprising the thermoplastic polymer; separating the solidified particles from the carrier fluid; and exposing the solidified particles to an optical absorber to produce the OACTP particles.
