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.

Three-dimensional (3D) printing with epoxy resin

In a three-dimensional printing method example, an epoxy mold compound build material is applied. A fusing agent is selectively applied on at least a portion of the epoxy mold compound build material. The epoxy mold compound build material is exposed to energy, thereby fusing the portion of the epoxy mold compound build material in contact with the fusing agent to form a layer.

Pigment based inks are provided. The inks include a non-polar carrier fluid; and a surface-functionalized pigment particle including a nitrogen-inked moiety to the surface of the pigment particle through a nitrogen link at one end of the nitrogen-linked moiety and a segment copolymer having at least two blocks attached at another end, the pigment particle suspended in the non-polar carrier fluid. A combination of an electronic display and an electronic ink employing the pigment and a process for making the pigment-based inks are also provided.

Inks including segment copolymer grafted pigments via azide chemistry

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.
