Patent number: 11780166Abstract: An example of an additive manufacturing system is disclosed. The example disclosed herein comprises a build material distributor, a preheating source, and a controller. The build material distributor is to form build material layers from an intended build material having a color. The preheating source is to emit energy at a wavelength related to the intended build material color so that at least a 40% of the energy is absorbed by the build material. The controller is to receive printing instructions to print a 3D object, wherein the printing instructions define an area to be fused in a build material layer. The controller is also to instruct the build material distributor to form the build material layer. The controller is further to control the preheating source to emit energy to preheat a zone comprising the area to be fused.Type: GrantFiled: April 10, 2018Date of Patent: October 10, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alex Veis, Joaquim Brugue Garvi, Esteve Comas Cespedes

Patent number: 11685173Abstract: In an example of the disclosure, a print job is received. The print job includes an image to be printed upon a substrate utilizing printheads. The print job is analyzed to determine a set of imaged segments, a set of image-adjacent segments, and a set of remote segments. The print job is printed upon the substrate utilizing a first set of printheads. A cooling liquid is applied to the set of image-adjacent segments of the printed print job utilizing a second set of printheads downstream from the first set of printheads. The printed job is exposed to an array of controllable illumination elements. The array of illumination elements is controlled to apply a drying illumination to the imaged segments and the image-adjacent segments of the printed print job, without providing the drying illumination to the remote segments.Type: GrantFiled: September 24, 2020Date of Patent: June 27, 2023Assignee: HP SCITEX LTD.Inventors: Alex Veis, Semion Birger
