An example of a penetrating agent for a three-dimensional (3D) printing process includes a surfactant blend, a co-solvent, a humectant present in an amount ranging from about 2 wt% to about 10 wt%, based on a total weight of the penetrating agent, and a balance of water. The surfactant blend includes a first non-ionic surfactant having a first hydrophilic chain length, a second non-ionic surfactant, wherein the second non-ionic surfactant is selected from the group consisting of a polyether siloxane and an alkoxylated alcohol, and an anionic surfactant. |
