Abstract: An example of a build material composition for three-dimensional (3D) printing includes a polymeric or polymeric composite build material and a wetting modifying agent. The wetting modifying agent is: (i) incorporated into the polymeric component of the polymeric or polymeric composite build material and changes the wetting behavior of the polymeric component; or (ii) selected from the group consisting of: a fluorotelomer; a C8-C20 alcohol; a methyltrialkyl ammonium chloride; docusate sodium salt; a polymer having a chemical structure of the polymeric component of the polymeric or polymeric composite build material modified to include a hydrophobic group or a hydrophilic group; and a combination thereof.

Abstract: In an example of a method for three-dimensional (3D) printing, a build material composition is applied to form a build material layer. The build material composition includes a polymeric or polymeric composite build material, and a precipitating agent. Based on a 3D object model, a fusing agent is selectively applied on at least a portion of the build material composition. The fusing agent includes a radiation absorber, which the precipitating agent precipitates. The build material composition is exposed to radiation to fuse the at least the portion to form a layer of a 3D part.
