Abstract: A hardening agent for three-dimensional printing includes a boron-containing hardener and a jettable liquid vehicle, and is devoid of a pigment and a dye. The boron-containing hardener is selected from the group consisting of a water dispersible boron-containing hardener present in an amount ranging from about 6 wt % to about 15 wt %, and a water soluble boron-containing hardener present in an amount ranging from greater than 1 wt % to about 20 wt %.

Abstract: A temperature sensor can include a resistor, a first electrical contact at a first end of the resistor, a second electrical contact at a second end of the resistor, and a resistance measuring device. The resistor can be formed of a matrix of sintered elemental transition metal particles interlocked with a matrix of fused thermoplastic polymer particles. The resistance measuring device can be connected to the first electrical contact and the second electrical contact to measure a resistance of the resistor.

Abstract: In an example implementation, a method of 3D printing includes receiving a 2D data slice derived from a 3D object model, where the 2D data slice defines an object area of a layer of build material that is to receive a liquid functional agent and be fused as a layer of a part. The method includes determining that the 2D data slice distinguishes first and second tolerance zones within the object area. The method includes controlling a printhead to print a liquid functional agent onto the layer of build material according to a first droplet ejection spacing when printing in the first tolerance zone, and controlling the printhead to print a liquid functional agent onto the layer of build material according to a second droplet ejection spacing when printing in the second tolerance zone.
