Abstract
This disclosure describes three-dimensional printing kits, methods, and systems for three-dimensional printing with triethylene glycol fusing agents. In one example, a three-dimensional printing kit can include a powder bed material including polymer particles and a fusing agent to selectively apply to the powder bed material. The fusing agent can include water, a radiation absorber, and triethylene glycol in an amount from about 20 wt % to about 35 wt %. The radiation absorber can absorb radiation energy and convert the radiation energy to heat to fuse the powder bed material.
