Publication number: 20240189895Abstract: A 3D printing system includes an ejector configured to receive a build material. The ejector includes a nozzle. The ejector is configured to eject a plurality of drops of the build material through the nozzle. The 3D printing system also includes a substrate positioned below the nozzle. The drops fall toward the substrate after being ejected from the nozzle. The drops form a 3D object on the substrate. The 3D printing system also includes a power source configured to generate an alternating electrical current. The 3D printing system also includes an electrode configured to generate a plasma in response to receiving the alternating electrical current. The drops, the 3D object, the substrate, or a combination thereof are positioned at least partially within the plasma.Type: ApplicationFiled: December 7, 2022Publication date: June 13, 2024Applicant: XEROX CORPORATIONInventors: Daniel Bullard, Patrick Y. Maeda, Warren Jackson, David K. Biegelsen

Publication number: 20240190071Abstract: An additive manufacturing device includes a stage configured to support a substrate. The device also includes a printhead disposed above the stage. The printhead is configured to heat a build material to a molten build material and to deposit the molten build material on the substrate in the form of droplets to fabricate an article. The device also includes a controlled heating and ablation system disposed proximal the printhead. The controlled heating and ablation system is configured to heat the substrate and ablate oxides on a surface of the substrate.Type: ApplicationFiled: December 7, 2022Publication date: June 13, 2024Applicant: XEROX CORPORATIONInventors: Patrick Y. Maeda, Daniel Bullard, Dogan Timucin

Publication number: 20080020226Abstract: Steel cabinet parts and other steel objects are electrocoated in a cationic resin-containing bath. The steel objects are chromium-coated, free of phosphate and preferably free of chromium oxide. The products are not significantly subject to filiform corrosion, and the process is economically beneficial because throwpower is more easily controlled than in previous processes.Type: ApplicationFiled: September 25, 2007Publication date: January 24, 2008Inventors: Jian Li, Daniel Bullard, Chyang Wu
