THREE-DIMENSIONAL PRINTING WITH FLAME RETARDANTS

Abrégé

A three-dimensional printing kit can include a polymeric build material and a fusing agent. The polymeric build material can include polymer particles having a D50 particle size from about 2 µm to about 150 µm. The fusing agent can include an aqueous liquid vehicle including water and an organic co-solvent, a radiation absorber to generate heat from absorbed electromagnetic radiation, and from about 5 wt% to about 20 wt% flame retardant including dicyandiamide.
