Abstract

Thermoplastic polymer particles suitable for use in additive manufacturing and related methods may comprise lignin. For example, said polymer particles may comprise a thermoplastic polymer, a lignin, optionally an emulsion stabilizer, and optionally a compatibilizer. Said polymer particles may be produced by melt emulsification methods and be highly spherical and, consequently, suited for selective laser sintering methods of additive manufacturing.
