Abstract: In an example of a three-dimensional (3D) printing method, a crystalline or semi-crystalline build material is applied. A temperature of the crystalline or semi-crystalline build material is maintained within 100° C. below a melting point of the crystalline or semi-crystalline build material. A melt flow property reduction agent is applied to at least a portion of the crystalline or semi-crystalline build material, and the at least the portion of the crystalline or semi-crystalline build material in contact with the melt flow property reduction agent melts or coalesces at the temperature.

Abstract: Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.

Abstract: The present disclosure is drawn to coalescent inks and material sets, such as for 3D printing. In one example, the coalescent ink can include a conjugated polymer, a colorant imparting a visible color to the coalescent ink, and an ink vehicle comprising a high boiling point co-solvent having a boiling point of 250° C. or greater. The high boiling point co-solvent can be present in an amount from about 1 wt % to about 4 wt % with respect to the coalescent ink.
