Patent number: 11148367Abstract: According to one example, there is provided a method of distributing build material in a 3D printing system. The method comprises moving a build material support positioned below a hopper, the movement to cause build material stored in the hopper to be deposited on the build material support, and moving a recoater to spread build material from the build material support over a build platform to form a layer of build material thereon, and to return any excess build material back to the build material support.Type: GrantFiled: August 31, 2016Date of Patent: October 19, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Randall Dean West, Matt G Driggers, Brent Ewald

Patent number: 10807362Abstract: An example printing subassembly includes a frame having first and second members spaced extending in a first direction. The frame can be removably coupled to a printing device. The first and second members are spaced from each other in a second direction, which is orthogonal to the first direction. The first and second directions are also orthogonal to a third direction. A printbar is coupled to the frame. An alignment system is coupled to the frame and includes at least four alignment features cooperating to constrain translation of the printing subassembly in the third direction and rotation about axes in the first and second directions with respect to the printing device.Type: GrantFiled: September 12, 2016Date of Patent: October 20, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Kenneth Russell Williams, Matt G Driggers
