Abstract: A multi-fluid kit for three-dimensional printing can include a fusing agent and a coloring agent. The fusing agent can include an electromagnetic radiation absorber in a first liquid vehicle. The electromagnetic radiation absorber can absorb radiation energy and can convert the radiation energy to heat. The coloring agent can include a magenta rhodamine dye and a fluorescence quenching iodide salt in a second liquid vehicle. A molar ratio of the magenta rhodamine dye to the fluorescence quenching iodide salt can range from about 1:1 to about 1:10.

Abstract: The present disclosure describes kits and compositions for three dimensional printing, systems for three-dimensional printing, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing comprises: a fusing agent comprising water and a radiation absorber, wherein the radiation absorber absorbs radiation energy and converts the radiation energy to heat; and a pore-promoting agent comprising water and a water-soluble pore-promoting compound, wherein the pore promoting compound chemically reacts at an elevated temperature to generate a gas, and wherein the water-soluble pore-promoting compound is selected from the group consisting of sodium bicarbonate, potassium bicarbonate, and combinations thereof.

Abstract: The present disclosure provides methods of three-dimensional printing, including iteratively applying individual build material layers of polyamide particles and selectively applying a fusing agent onto the individual build material layers to form individually patterned object layers. The fusing agent can include water and a radiation absorber. The method can also include selectively applying a pore-promoting agent onto the individual build material layers at some or all of the individually pattered object layers to form a pore-generating region, and iteratively exposing the individual build material layers to electromagnetic energy to generate molten polymer from polyamide particles in contact with the radiation absorber that upon cooling forms fused polymer body. A material used to form the fused polymer body without pores can exhibit a material dielectric permittivity, and the fused polymer body at a location that includes the pores can exhibit a decreased dielectric permittivity.

Abstract: A three-dimensional printing kit can include a polymer build material and a fusing agent. The polymer build material can include from about 80 wt % to about 100 wt % polymeric particles. The fusing agent can include an aqueous liquid vehicle, an electromagnetic radiation absorber to absorb radiation energy and convert the radiation energy to heat, and an endothermic decomposition compound that can undergo thermal decomposition at a temperature ranging from about 60° C. to about 400° C.

Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor, may cause the processor to identify a first orientation of a first surface portion of a three-dimensional (3D) model. The instructions may also cause the processor to, based on the identified first orientation of the first surface portion, determine a first thickness of a first section of a first geological region of the 3D model, the first section being adjacent to the first surface portion, in which a plurality of different orientations of 3D model surface portions are correlated to a plurality of different thicknesses. The instructions may further cause the processor to define the first section of the first geological region to have the determined first thickness.

Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

Abstract: An optical system, used for scanning, forms an image using reflective optical surfaces. The system may be telecentric, and may form an image that is reduced in size as compared with the scanned original. Several image-forming optical channels may be combined to form a page-wide scanning array.
