Abstract

See full text

A three-dimensional (3D) printing system includes a fabrication bed, a build material to be introduced into the fabrication bed, an inkjet applicator, a coalescing agent to be selectively introduced by the inkjet applicator onto the build material in the fabrication bed, and a radiation source to expose the coalescing agent and the build material in the fabrication bed to electromagnetic radiation. The coalescing agent includes a co-solvent having a boiling point of less than 300 C, a surfactant having a hydrophilic lipophilic balance (HLB) value that is less than 10, a carbon black pigment, a polymeric dispersant, and a balance of water.
