Abstract: In example implementations, a three-dimensional printing kit for printing a colorless three-dimensional object in a three-dimensional printing system is provided. The three-dimensional printing kit includes a build material and an ultraviolet (UV) fusing agent. The UV fusing agent includes water, a UV light absorber, about 10-50 weight percent (wt %) of a first solvent to provide a polymer plasticizer, and about 30-50 wt % a second solvent that is water miscible and dissolves the UV light absorber.

Abstract: An example of a three-dimensional (3D) printing energy absorbing composition includes carbon black particles present in an amount ranging from about 0.01 wt % active to about 3 wt % active, based on a total weight of the 3D printing energy absorbing composition; benzyl alcohol present in an amount ranging from about 1 wt % active to about 40 wt % active, based on the total weight of the 3D printing energy absorbing composition; a solvent for benzyl alcohol having a boiling point of 150 C or higher present in an amount ranging from about 20 wt % active to about 60 wt % active, based on the total weight of the 3D printing energy absorbing composition; and a balance of water.

Abstract: Examples of the present disclosure are directed toward fusing agent compositions. An example fusing agent composition includes a radiation absorber, a co-solvent mixture, and a balance of water. In various examples, the radiation absorber is present in an amount ranging from about 0.005 weight percent (wt %) to about 1.0 wt % of a total weight of the fusing agent composition, wherein the radiation absorber absorbs radiation at a wavelength range within the visible light spectrum.

Abstract: A three-dimensional printing kit includes a substantially colorless fusing agent and a color assist agent. The fusing agent includes a liquid vehicle including water, a co-solvent, and an amino acid stabilizer. The fusing agent further includes an infrared (IR) absorbing pigment dispersion including an IR absorbing pigment present in an amount ranging from about 0.01 wt % active to about 1.6 wt % active, based on a total weight of the fusing agent. The color assist agent includes a liquid vehicle including water and a plasticizing co-solvent, and a dye dissolved in the liquid vehicle. Also disclosed is a method of making a colored 3D printed object.

Abstract: Three-dimensionally printed parts are exposed to different processes enabling the parts or components thereof to be reused. In one example, a 3D printed part is exposed to an absorber extraction process, and the absorber extracted from the 3D printed part is used to form a second-generation fusing agent. In another example, a 3D printed part is divided into smaller pieces and injection molded to form a second-generation 3D object with unexpectedly high mechanical properties.

Abstract: In example implementations, a method is disclosed. The method includes dispensing a layer of an optically clear build material, dispensing a fusing agent onto a first portion of the layer of the optically clear build material, dispensing an invisible fluorescence compound on a second portion of the layer of the optically clear build material, and applying ultraviolet (UV) light to the layer to fuse the first portion and the second portion of the optically clear build material that received the fusing agent and the invisible fluorescence compound. The invisible fluorescence compound is to print an embedded feature in the layer that is invisible under a first light and visible under a second light.

Abstract: In one example of the disclosure, a print agent is applied upon a length of web substrate. A dryer is utilized to dry the web substrate length. Moisture is applied to the web substrate length. The moisturized web substrate length is wound upon a spool to form a top liner length, with no dryer to be utilized to dry the web substrate length between the moisture application and the winding.
