Abstract: An example of a three-dimensional (3D) printing kit includes a build material composition and a fusing agent to be applied to at least a portion of the build material composition during 3D printing. The build material composition includes a semi-crystalline thermoplastic polymer having a surface energy density greater than 41 mN/m. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the semi-crystalline thermoplastic polymer in the at least the portion.
