    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.

    Abstract: In an example of a method for making polymer-encapsulated metallic ink pigment particles, a layer of a transparent resin dispersion is disposed on a flexible substrate. The resin dispersion layer is substantially dried, and a base resin layer is formed. A slurry is disposed onto the base resin layer. The slurry includes metallic pigment particles and polymer particles dispersed in a non-aqueous carrier. The slurry is dried to form a metallic pigment-polymer sheet. Another layer of the transparent resin dispersion is disposed on the metallic pigment-polymer sheet and is dried. A coating resin layer is formed. The metallic pigment-polymer sheet and the base and coating transparent resin layers form a tri-layer film having the metallic pigment particles encapsulated between the base and coating transparent resin layers.

    Abstract: According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies may include depositing surface-enhanced spectroscopy (SES) elements onto respective tips of nano-fingers, in which the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of groups of adjacent ones of the nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to be bonded together when the nano-fingers are partially collapsed. The methods also include causing the nano-fingers to partially collapse toward adjacent ones of the nano-fingers to cause a plurality of SES elements on respective groups of the nano-fingers to be in relatively close proximities to each other and form respective clusters of SES elements, introducing additional particles that are to attach onto the clusters of SES elements, and causing the clusters of SES elements to detach from the nano-fingers.
