    Abstract: In a three-dimensional printing method example, a build material, including an epoxy resin powder, is applied. A hardener liquid is selectively applied on at least a portion of the build material. The portion of the build material in contact with the hardener liquid is allowed to cure to form a layer of a 3D part. In another three-dimensional printing method example, a filler build material is applied. A liquid epoxy resin is selectively applied on at least a portion of the filler. A hardener liquid is selectively applied on the at least the portion of the filler. The portion of the filler in contact with the liquid epoxy resin and the hardener liquid is allowed to cure to form a layer of a 3D part.

    Abstract: Electronic inks are disclosed herein. An example of the electronic ink includes a non-polar carrier fluid, a colorant particle dispersion, and a charge director. The colorant particle dispersion includes another non-polar carrier fluid (which may be the same as, or different from the non-polar carrier fluid), colorant particles, and chargeable dispersant molecules bonded to the colorant particles. The charge director is to charge the chargeable dispersant molecules.

    Abstract: Pigment based inks are provided. The inks include a non-polar carrier fluid and a surface-functionalized pigment particle including a nitrogen-linked moiety to the surface of the pigment particle through a nitrogen link at one end of the nitrogen-linked moiety and a graft copolymer having two or three blocks attached at another end, the pigment particle suspended in the non-polar carrier fluid, the nitrogen-linked moiety further including an alkyl chain interposed between the nitrogen-linked moiety and the graft copolymer having the structure (I), where X is the nitrogen-linked moiety and Y is a copolymer, and the letter a is an integer between 0 and about 5,000, while the letter b is an integer of 2 or more.

    Abstract: In a three-dimensional printing method example, a build material, including an epoxy resin powder, is applied. A hardener liquid is selectively applied on at least a portion of the build material. The portion of the build material in contact with the hardener liquid is allowed to cure to form a layer of a 3D part. In another three-dimensional printing method example, a filler build material is applied. A liquid epoxy resin is selectively applied on at least a portion of the filler. A hardener liquid is selectively applied on the at least the portion of the filler. The portion of the filler in contact with the liquid epoxy resin and the hardener liquid is allowed to cure to form a layer of a 3D part.
