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 or amorphous thermoplastic polymer having a predicted total dimension change during 3D printing ranging from about −4% to about 9%. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the semi-crystalline or amorphous thermoplastic polymer in the at least the portion. The fusing agent is a core fusing agent and the energy absorber has absorption at least at wavelengths ranging from 400 nm to 780 nm; or the fusing agent is a primer fusing agent and the energy absorber has absorption at wavelengths ranging from 800 nm to 4000 nm and has transparency at wavelengths ranging from 400 nm to 780 nm.
