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: 11673289Abstract: Methods and systems are described for fabricating a component using 3D printing. A 3D printed piece is created including a body of the component, a support structure, and a first sacrificial interface region coupling the body of the component to the support structure. The body of the component is formed of a first metal or ceramic material and the first sacrificial interface region is formed at least partially of a second metal or ceramic material. The body of the component is then separated from the support structure by applying a chemical or electrochemical dissolution process to the 3D printed piece. Because the second metal or ceramic material is less resistant to the dissolution process than the first metal or ceramic material, the first sacrificial interface region at least partially dissolves, thereby separating the body of the metal component from the support structure, without dissolving the body of the component.Type: GrantFiled: February 16, 2017Date of Patent: June 13, 2023Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY, THE PENN STATE RESEARCH FOUNDATIONInventors: Owen Hildreth, Abdalla Nassar, Timothy W.
