Abstract
A three-dimensional printing kit can include a build material, a fusing agent, and a flame retardant. The build material can include polyamide particles. The fusing agent can include a radiation absorber to generate heat from absorbed electromagnetic radiation and an aqueous liquid vehicle including water. The flame retardant can include 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. The flame retardant can be included at from about 5 wt % to about 30 wt % in the fusing agent, at from about 5 wt % to about 30 wt % in a flame retardant agent if present that is separate from the fusing agent, or at from about 5 wt % to about 30 wt % in the fusing agent and from about 5 wt % to about 30 wt % in the flame retardant agent.
