Publication number: 20180036950Abstract: A method for determining a parameter of a process associated with a 3D printing process provided. A first amount corresponding to an object of fused powder surrounded by non-fused powder is used. The first amount is separated into a second amount of non-fused powder and a third amount corresponding to the object including residual powder material attached.

Publication number: 20180017956Abstract: A method of fabricating a three dimensional object in an additive layer manufacturing process, e.g. 3D printing, wherein a three dimensional design of the three dimensional object is modelled as a plurality of three dimensional pixels or vortexes. For every pixel or vortex, at least one parameter is calculated and is used to select a setting for use when fabricating the three dimensional object. The parameter may be a speed or rate at which heat will diffuse away from the pixel or vortex, or a weighted density surrounding the pixel or vortex. The method provides higher quality fabrication of the three dimensional object.Type: ApplicationFiled: April 24, 2015Publication date: January 18, 2018Inventors: Juan Manuel Garcia Reyero Vinas, Sergio Puigardeu Aramendia, Alejandro Manuel De Pena, David Ramirez Muela

Patent number: 9669634Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurized gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurized gas.Type: GrantFiled: September 24, 2015Date of Patent: June 6, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Francesc Ros Cerro, Macià Solé Pons, David Ramírez Muela, Li Qian

Publication number: 20170036458Abstract: A method includes printing an image on substrate by a printhead using ultraviolet (UV) curable ink. The method includes selectively applying a first amount of UV radiation by a first region of a light source to a first area of the image after a first amount of time passes from printing the first area to form a first gloss level area having a glossy finish. The method also includes selectively applying a second amount of UV radiation by a second region of the light source to a second area of the image after a second amount of time passes from printing the second area to form a second gloss level area having a matte finish. At least one of the second amount of UV radiation is greater than the first amount of UV radiation and the first amount of time is greater than the second amount of time.Type: ApplicationFiled: October 19, 2016Publication date: February 9, 2017Inventors: Alex Andrea Tallada, Carmen Blasco Cortes, Xavier Quintero Ruiz, David Ramirez Muela

Publication number: 20160332376Abstract: Examples are described that generate control data (280) for production of a three-dimensional object. Build material profile data (260) is accessed for an indicated build material. The build material profile data for a given build material defines one or more parameter values that are dependent on the properties of the given build material and that are configured to generate a three-dimensional object with predefined build properties. Certain examples are arranged to generate control data for the production of a three-dimensional object by applying build material profile data to received object data (230).Type: ApplicationFiled: September 30, 2014Publication date: November 17, 2016Inventors: David Ramirez Muela, Sergio Puigardeu Aramendia, Pol Fornos, Salvador Sanchez Ribes
