Abstract
A method of three-dimensional printing can include iteratively applying a polymer build material as individual layers to a powder bed, where the polymer build material includes from about 80 wt % to 100 wt % polymeric particles, and based on a three-dimensional object model, selectively applying a coalescing agent onto individual layers of the polymer build material. The coalescing agent can include an aqueous liquid vehicle and a coalescing solvent that depresses a melting point of the polymeric particles. The method can include exposing the powder bed to heat to selectively coalesce portions of individual layers of the polymer build material in contact with the coalescing solvent. The heat may not be sufficient to coalesce the polymer build material that is not in contact with the coalescing solvent and may be sufficient to fuse the polymeric particles in contact with the coalescing solvent together to form a three-dimensional object.
