Patent number: 11826961Abstract: In an example, a method include receiving a data model of an object to be generated in additive manufacturing at a processor, the data model comprising object property data. A segmentation of a virtual build volume comprising at least a portion of the object into a plurality of nested segments may be derived. A first segment may be associated with first object generation parameters and a second segment may be associated with second, different, object generation parameters. A number of nested segments to be derived may be determined based on at least one of a geometry of the object and an intended object property.Type: GrantFiled: July 10, 2017Date of Patent: November 28, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Hector Jose Lebron, Jake Wright, Stephen G.

Patent number: 8356877Abstract: The present invention is embodied in a printing system (100) that includes a print head (120) having a controller (110), a temperature sensor (116) and a priming system (126) configured to apply a fluid pressure externally to the print head (120) to purge the print head with fluid, wherein purging the print head (120) with fluid has an effect of reducing the print head temperature. The controller (110) is configured to activate the priming system (126) for purging the printhead (120) with fluid, monitor a signal from the temperature sensor (406), and determine (418) whether activating the primer has resulted in sufficient fluid passing through the print head (120) based upon monitoring the signal from the temperature sensor (116).Type: GrantFiled: August 11, 2008Date of Patent: January 22, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Hector Jose Lebron, Anders T.
