Abstract
Provided in one example herein is a three-dimensional printing method, comprising: (A) forming a layer comprising particles comprising a polymer and cavities between the particles, wherein the particles have an average diameter of between about 5 μm and about 250 μm; (B) disposing a liquid suspension over at least a portion of the layer such that the liquid suspension infiltrates into the cavities, wherein the liquid suspension comprises a radiation-absorbing coalescent agent and nanoparticles having an average diameter of less than or equal to about 500 nm; (C) forming an object slice by exposing the infiltrated layer to a radiant energy, wherein the object slice comprises a polymeric matrix comprising the polymeric particles, at least some of which are fused to one another, and the nanoparticles within the polymeric matrix; and (D) repeating (A) to (C) to form the three-dimensional object comprising multiple object slices bound depth-wise to one another.
