Abstract: A multi-fluid kit for three-dimensional printing can include a fusing agent and a nanoparticle-containing agent. The fusing agent can include water and a radiation absorber, where the radiation absorber absorbs radiation energy and converts the radiation energy to heat. The nanoparticle-containing agent can include a liquid vehicle, high density nanoparticles, and a nanoparticle suspension compound selected from the group consisting of terpineol, ethyl cellulose, and a combination thereof.

Abstract: The present disclosure relates a method of 3-dimensional printing a printed part. The method comprises printing an inkjet dopant composition at selected locations on a layer of build material comprising polymer particles. The inkjet dopant composition comprises a dopant dispersed or dissolved in a liquid carrier. Polymer particles at selected areas of the layer of build material are then fused to form a fused polymer layer comprising the dopant. The selected areas of the layer of build material include areas of the layer of build material that have not been printed with the inkjet dopant composition.

Abstract: Certain methods and systems are described that allow the spectral control of a print output. A plurality of colorants are used where one or more colorants contain nanoparticles. Each colorants has a specified spectral range corresponding to the constituent nanoparticles. To print with these colorants a spectral separation may be used that maps an input color with associated spectral information or direct spectral information to print control data, the print control data having defined values for depositions with each combination of the colorants. The spectral separation may be constructed by characterizing a set of spectral Neugebauer primaries for the plurality of colorants.

Abstract: Certain methods and systems are described for encoding data in an image. According to an example, a set of metamers under a first set of conditions may be determined that vary under a second set of conditions. These may be used to generate a set of color mappings for a sampled color value, each color mapping being used for a different data value in the data. As such the data values may be detectable when the image is observed under the second set of conditions but not detectable when the image is observed under the first set of conditions.

Abstract: In one example in accordance with the present disclosure, a three-dimensional (3D) printed sensor system is described. The 3D printed sensor system includes a 3D printed object. The 3D printed sensor system also includes a 3D printed sensor on a body of the 3D printed object. The 3D printed sensor includes a dielectric region disposed between electrodes. A capacitance of the dielectric region is indicative of an environmental condition of the 3D printed object. The 3D printed sensor system also includes a controller integrated with the body of the 3D printed object. The controller is to measure a capacitance of the 3D printed sensor.

Abstract: A method for generating a color mapping for a printing apparatus is described. The printing apparatus includes a plurality of colorants including a first colorant configured to reflect radiation having a first set of wavelengths and a second colorant configured to absorb radiation having a second set of wavelengths and emit radiation having a third set of wavelengths. The method includes obtaining spectral characteristics for the plurality of colorants, computing a gamut of colors available to the printing apparatus and determining a color mapping from an input color space to an output color space.
