Zusammenfassung:	The present disclosure describes three-dimensional printing kits, methods of making three-dimensional printed objects, and three-dimensional printing systems. In one example, a three-dimensional printing kit can include a power bed material including thermoplastic polymer particles, a fusing agent to selectively apply to the powder bed material, and a post-processing agent to apply to a three-dimensional printed object. The fusing agent can include water and a radiation absorber that absorbs radiation and converts the radiation energy to heat. The post-processing agent can include a curable epoxy resin, where the epoxy resin, when cured, has a higher elastic modulus than the thermoplastic polymer particles.
