Claim 12:
13. A method of making a three-dimensional printed article, comprising:
iteratively applying individual build material layers of a powder bed material including polymer particles to a powder bed;
based on a three-dimensional object model, selectively jetting a fusing agent onto individual build material layers, wherein the fusing agent comprises water and a radiation absorber;
based on the three-dimensional object model, selectively jetting a detailing agent onto individual build material layers laterally at a border between a first area where the powder bed material is contacted by the fusing agent and a second area where the powder bed material is not contacted by the fusing agent, wherein the detailing agent comprises water and from about 0.1 wt % to about 20 wt % of organosilanes based on a total weight of the detailing agent, wherein the organosilanes include an organosilane compound with a central silicon having both a water-solubilizing group and multiple hydrolyzable moieties attached to the central silicon; and
exposing the powder bed material to energy to selectively fuse the polymer particles in contact with the radiation absorber to form a fused polymer matrix at individual build material layers.
