Patent number: 10807305Abstract: In one implementation, a system comprising a target engine, a thermal engine, and a sacrificial object engine is described. The target engine is to identify a target region of a build bed of a print device where a target object is to be located. The thermal engine is to identify a temperature level of the target region. The sacrificial object engine is to identify an object location to place a sacrificial object in response to a determination that the temperature level of the target region is deficient to achieve a temperature threshold for production.Type: GrantFiled: June 2, 2015Date of Patent: October 20, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Yan Zhao, Hou T.

Publication number: 20200262191Abstract: A three-dimensional object may be generated. Coalescing agent may be selectively delivered on a portion of a first layer of build material on a support member or previous layer. Energy may be applied to the first layer to cause the portion of the first layer to coalesce and solidify. A second layer of the build material may be provided on the first layer. While the second layer does not have coalescing agent delivered thereon, energy may be applied to the second layer such that energy may propagate through the second layer to the first layer to cause the portion of the first layer to coalesce and further solidify.Type: ApplicationFiled: May 8, 2020Publication date: August 20, 2020Inventors: Alejandro Manuel De Pena, Pavel Kornilovich, David H.

Patent number: 10730282Abstract: In an example, a method includes forming, at an additive manufacturing apparatus, a first layer of build material to be processed in the generation of an object. A print agent is selectively applied onto the first layer based on a first print instruction associated with the first layer. Energy is applied to the first layer to cause fusion in a region of the first layer. The method further comprises: measuring the temperature of the first layer at a plurality of locations to form a measured temperature distribution profile; comparing the measured temperature distribution profile against a predicted temperature distribution profile to generate a difference; and correcting a temperature distribution profile of a subsequent layer of the build material following fusion of the subsequent layer based on the difference by modifying a second print instruction associated with the subsequent layer.Type: GrantFiled: May 12, 2016Date of Patent: August 4, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alejandro Manuel De Pena, Sergio Puigardeu Aramendia, David Ramirez Muela
