Patent number: 11003166Abstract: In an example, a method includes receiving a first data model of an object to be generated in additive manufacturing, at a processor. Using the processor, a second data model may be determined. Determining the second data model may include generating for each of plurality of contiguous, non-overlapping sub-volumes of a volume containing the object, a sub-volume octree characterising the sub-volume and having a root node. Determining the second data model may further include generating a volume octree characterising the volume containing the object, the volume octree characterising in its lowest nodes the root nodes of the sub-volume octrees.Type: GrantFiled: October 12, 2016Date of Patent: May 11, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alex Carruesco Llorens, Alvar Vinacua, Pere Brunet, Sergio Gonzalez, Jordi Gonzalez Rogel, Marc Comino, Josep Giralt Adroher, Lluis Abello Rosello, Sebastia Cortes I Herms

Patent number: 10853998Abstract: In an example, a method includes receiving, at a processor, data representing at least part of an object to be manufactured in a layer-by-layer manufacturing process. A serialised octree representation of at least part of the object may be generated from the data. In the serialised octree representation, nodes are ordered such that (i) a node representing a volume which includes a layer of the object to be generated earlier in an intended order of object generation precedes a node representing a volume which consists of layer(s) of the object to be generated subsequently; (ii) nodes representing a volume which includes a given layer of the object are ordered based on a level of the nodes within the octree representation, wherein parent nodes appear before descendent nodes; and (iii) nodes representing a volume which includes a given layer of the object and being of the same level within the octree representation are ordered according to a location encoding pattern.Type: GrantFiled: October 12, 2016Date of Patent: December 1, 2020Assignee: Hewlett-Packard Development Company, L.P.CInventors: Lluis Abello Rosello, Alvar Vinacua, Pere Brunet, Marc Comino, Jordi Gonzalez Rogel, Sergio Gonzalez, Josep Giralt Adroher, Sebastia Cortes Herms, Alex Carruesco Llorens

Publication number: 20190205483Abstract: In an example, a method comprises receiving machine-readable data relating to a three-dimensional object to be generated by an additive manufacturing apparatus, the machine-readable data being in a first data format. The method may further include processing, by a processor, the machine-readable data. The processing may comprise converting, by a processor, the machine-readable data from the first data format into a second data format suitable for use by the additive manufacturing apparatus to generate the three-dimensional object; and extracting metadata from the machine-readable data. The method may further include providing the processed data to an additive manufacturing apparatus for use in generating the three-dimensional object.Type: ApplicationFiled: May 12, 2016Publication date: July 4, 2019Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Alejandro Manuel De Pena, Josep Giralt Adroher, Sebastia Cortes I Hermes
