Patent number: 11230060Abstract: In one example in accordance with the present disclosure, an additive manufacturing build unit is described. The additive manufacturing build unit includes a vibrating bed on which a volume of build material is to be disposed. The bed is to vibrate to remove excess build material. A non-vibrating frame of the build unit supports the vibrating bed. The build unit also includes a bed-frame interface to: couple the vibrating bed to the non-vibrating bed frame, and isolate vibrations to the vibrating bed. A flexible seal of the build unit is disposed between the vibrating bed and non-vibrating frame. The flexible seal prevents build material from contaminating an additive manufacturing system in which the additive manufacturing build unit is disposed and allows relative motion between the vibrating bed and the non-vibrating frame.Type: GrantFiled: July 6, 2017Date of Patent: January 25, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert Lawrence Winburne, Joshua Schmale, Tait A.

Publication number: 20210370603Abstract: Examples of a fluid flow device for an additive manufacturing printer are disclosed. In an implementation, the fluid flow device includes a body including an inlet, an outlet, a first wall, a second wall opposite the first wall, and a fluid flow passage in fluid communication with the inlet and outlet. In addition, the fluid flow device includes a port into the fluid flow passage, through the first wall along an axis, the port to communicate with a chamber that receives powder during a printing operation. Further, the fluid flow device includes a plate within the fluid flow passage and axially spaced between the port and the second wall such that the fluid flow passage is divided into a first passage between the port and the plate and a second passage between the plate and the second wall, the first passage to receive powder from the chamber through the port.Type: ApplicationFiled: July 18, 2018Publication date: December 2, 2021Inventors: Theodore J. Conley, Robert Lawrence Winburne
