Patent number: 11685115Abstract: In one example in accordance with the present disclosure, an additive manufacturing module is described. The additive manufacturing module includes an agent distributor to selectively distribute a fabrication agent onto layers of build material. The agent distributor includes at least one fluidic ejection die. Each fluidic ejection die includes a plurality of nozzles arranged along a die length and a die width, the plurality of nozzles arranged such that, for each set of neighboring nozzles, a respective subset of each set of neighboring nozzles are positioned at different die width positions along the width of the fluidic ejection die. The fluidic ejection die also includes, for each respective nozzle of the plurality of nozzles, a respective ejection chamber fluidically coupled to the respective nozzle and for each respective ejection chamber, at least one respective fluid feed hole fluidically coupled to the respective ejection chamber.Type: GrantFiled: March 12, 2018Date of Patent: June 27, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: James R Przybyla, Jason Hower, Michael G Monroe, Galen P Cook

Patent number: 11534824Abstract: An example of a composition includes a host metal present in an amount ranging from about 95.00 weight percent to about 99.99 weight percent, based on a total weight of the composition. A flow additive is present in an amount ranging from about 0.01 weight percent to about 5.00 weight percent, based on the total weight of the composition. The flow additive consists of a metal containing compound that is reducible to an elemental metal in a reducing environment at a reducing temperature less than or equal to a sintering temperature of the host metal. The elemental metal is capable of being incorporated into a bulk metal phase of the host metal in a final metal object. The composition is spreadable, having a Hausner Ratio less than 1.25.Type: GrantFiled: April 19, 2018Date of Patent: December 27, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Vladek Kasperchik, Mohammed S. Shaarawi, James McKinnell, Michael G. Monroe, Jason Hower

Publication number: 20210331246Abstract: In an example implementation, a 3D printing system to remove components of a liquid agent includes a permeable surface. Build material formed on the permeable surface can be heated to generate vapor from a component of the liquid agent. The vapor can be drawn out of the build material through the permeable surface.Type: ApplicationFiled: June 5, 2018Publication date: October 28, 2021Inventors: Jason Hower, Michael G. Monroe, James E Fischer, Andrew L Van Brocklin, Ravi Prasad
