Abstract
An example of a three-dimensional (3D) printing composition 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 one of: (i) a thermoplastic elastomer having a flow parameter characterized by a consolidation resistance value ranging from about 8 to about 30, and a tap density characterized by an n1/2 value ranging from 5 taps to 30 taps; or (ii) a polyamide-like material having a flow parameter characterized by a consolidation resistance value ranging from about 75 to about 120, and a tap density characterized by an n1/2 value ranging from 5 taps to 30 taps. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the thermoplastic elastomer or the polyamide-like material in the at least the portion.
