Publication number: 20240109128Abstract: According to an example, a device comprises a sidewall and a base movable relative to the sidewall. The sidewall and base define an internal volume for receipt of build material in an additive manufacturing process. The example device further comprises a membrane. A first end of the membrane is attached to the base such that the membrane is movable with the base. The membrane at least partially extends along the sidewall to form a flexible barrier between the internal volume and the sidewall.Type: ApplicationFiled: February 24, 2020Publication date: April 4, 2024Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Alejandro Rodriguez Romero, Gabriel De La Cal Mendoza, Albert Rodriguez Fernandez, Francesc Melia Sune

Publication number: 20220402206Abstract: A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a non-powered compartment defining a chamber to contain build material, and a passive latching element connected to a lateral wall of the compartment to be engaged with a complementary latching element of a platform. A drive mechanism of a 3D printing device is engageable with the platform to apply an upward vertical force to the platform to move the platform upwardly. The complementary latching elements are to: passively latch the platform and the compartment together at a latched position such that upward movement of the platform causes upward movement of the compartment until the compartment is restrained at a sealing position; and to passively unlatch the platform from the compartment, upon further upward movement of the platform.Type: ApplicationFiled: March 24, 2020Publication date: December 22, 2022Inventors: Albert RODRIGUEZ FERNANDEZ, Marius VALLES GONZALEZ, Gabriel DE LA CAL MENDOZA, Joaquim BRUGUE GARVI, Francesc MELIA SUNE

Publication number: 20220371278Abstract: A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a build compartment defining a build chamber within which a 3D object is to be generated; and a non-powered platform, moveable within the build chamber, comprising a platform drive interface to engage with an external drive mechanism to cause the platform to move. The 3D printing apparatus further comprises a powder compartment located laterally adjacent to the build compartment, within which build material is to be stored for use in the generation of the 3D object. The 3D printing apparatus also comprises a locking interface to couple the 3D printing apparatus with an external hosting device.Type: ApplicationFiled: January 30, 2020Publication date: November 24, 2022Applicant: Hewlett-Packard Development Company, L.P.Inventors: Pau MARTIN VIDAL, Marius VALLES GONZALEZ, Gerard MOSQUERA DONATE, Albert RODRIGUEZ FERNANDEZ, Gabriel DE LA CAL MENDOZA, Francesc MELIA SUNE

Publication number: 20220016844Abstract: This build material spreading apparatus for additive manufacturing, includes a movable spreader, a build material dispenser, and a controller to calibrate the amount of build material needed to form a layer. The controller controls the build material dispenser to dispense a predetermined amount of build material. The controller controls the movable spreader to spread the dispensed build material to form a layer. The controller determines an amount of build material remaining after spreading. The controller modifies, based on the determined amount of remaining build material, the predetermined amount of build material to be subsequently provided by the build material dispenser.Type: ApplicationFiled: April 30, 2019Publication date: January 20, 2022Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Fernando JUAN JOVER, Gerard MOSQUERA DONATE, Berta ROIG GRAU, Francesc MELIA SUNE

Patent number: 10245854Abstract: In one example, a printer having a removably-installable platen. The platen has a platen type. A surface of the platen has a feature that is indicative of the platen type. The printer includes a single platen-type-discriminating sensor. The sensor detects a distinguishing characteristic of the feature. A controller determines the platen type from the distinguishing characteristic.Type: GrantFiled: April 8, 2015Date of Patent: April 2, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Carles Flotats Vilagrasa, Francesc Melia Sune, David Toussaint

Patent number: 8388102Abstract: A method of maintaining a fluid applicator unit of an image forming apparatus in which the fluid applicator unit includes a nozzle surface having nozzles is disclosed. The method includes ejecting fluid through nozzles of a fluid applicator unit of an image forming apparatus during a maintenance mode to maintain flow paths therethrough such that the fluid is emitted from the nozzles in a form of fluid drops. The method also includes receiving the fluid drops emitted from the nozzles during the maintenance mode on a receiving member to form waste liquid therefrom and directing the waste liquid from the receiving member to a waste receiving unit through a liquid passage. The method also includes directing aerosol formed from the fluid drops emitted from the nozzles to the aerosol receiving unit through an aerosol passage such that the aerosol passage is separate from the liquid passage and receiving the aerosol directed to the aerosol receiving unit.Type: GrantFiled: March 30, 2011Date of Patent: March 5, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ainhoa Urbistondo, Marta Coma, Francesc Melia
