Abstract
In a three-dimensional printing method example, a polymeric or polymeric composite build material is applied. A fusing agent is applied on at least a portion of the build material. The fusing agent includes an aqueous or non-aqueous vehicle and a plasmonic resonance absorber having absorption at wavelengths ranging from 800 nm to 4000 nm and having transparency at wavelengths ranging from 400 nm to 780 nm dispersed in the aqueous or non-aqueous vehicle. The build material is exposed to electromagnetic radiation, thereby fusing the portion of the build material in contact with the fusing agent to form a layer.
