Abstract: In a 3D printing method, a sinterable material is applied and heated to a temperature ranging from about 50° C. to about 400° C. A coalescent agent is selectively applied on a portion of the sinterable material, and a modifying agent is selectively applied on the portion and/or on another portion of the sinterable material. The modifying agent consists of an inorganic salt, a surfactant, a co-solvent, a humectant, a biocide, and water. The sinterable material is exposed to radiation, whereby the coalescent agent at least partially cures the portion of the sinterable material in contact with the coalescent agent, and the modifying agent i) reduces curing of the portion of the sinterable material in contact with both the coalescent agent and the modifying agent ii) prevents curing of the other portion of the sinterable material in contact with the modifying agent, or iii) both i and ii.
