  • Publication number: 20190039293
    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.

  • Publication number: 20190030799
    Abstract: 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.

  • Publication number: 20190009465
    Abstract: In a three-dimensional (3D) printing method example, build material granules are applied. Each of the build material granules includes a plurality of primary ceramic particles agglomerated together by a binder that is at least partially soluble in a primary solvent of a fusing agent. Pressure is applied to crush the build material granules. The fusing agent is selectively applied on at least a portion of the build material granules or the crushed build material granules to pattern the portion, and to introduce a latent binder to the portion. The application of the build material granules, the application of the pressure, and the selectively application of the fusing agent are repeated to create a green body. The latent binder is activated by heating the green body in order to produce a cured green body.

  • Publication number: 20180272561
    Abstract: In a three-dimensional printing method example, build material granules are applied. Each of the build material granules includes uncoated, primary ceramic particles agglomerated together by a binder that is soluble in a primary solvent of a fusing agent. The fusing agent is selectively applied on at least a portion of the build material granules. The binder dissolves and a green body including a slurry of the uncoated, ceramic particles is created.

  • Patent number: 8573747
    Abstract: An electrostatic liquid-ejection actuation mechanism includes a membrane, a frame, and one or more deformable beams. The frame has two sides and a number of cross members that are non-parallel to the two sides. The two sides and the cross members define one or more areas individually corresponding to one or more liquid chambers. The deformable beams are disposed between the membrane and the frame. The deformable beams individually correspond to the liquid chambers, and define a number of slits. Each slit is adjacent to one of the two sides of the frame. The deformable beams have a width that is less than a width of the liquid chambers, due at least to the slits.

  • Patent number: 8330955
    Abstract: A color detector includes a light source, a photodiode, and a filter tuned to only allow light of a specific color to pass through to the photodiode. When the light reaches the photodiode, the photodiode outputs a current that indicates that the color is present in the light. The filter may include a pair of partially reflective layers consisting of a reflective metal, such as silver. To prevent the metal from oxidizing or reacting with the environment, the partially reflective layers may be coated with a protective layer, such as aluminum nitride. The color detector may further include a color enhancing layer. Finally, the color detector may include a capping layer. Accordingly, the color detector provided herein allows for the filter to use metals for partially reflective layers that would normally oxidize, as well as detect light of a specific spectrum of wavelengths.
