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 polyamide having: an avalanche angle ranging from about 35 degrees to about 55 degrees; a break energy ranging from about 25 kJ/kg to about 57 kJ/kg; and an avalanche energy ranging from about 7 kJ/kg to about 22 kJ/kg. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the polyamide in the at least the portion.
