  • Translating contents of a print chamber to a secondary chamber
    Patent number: 11760025
    Abstract: A platform is moved to translate contents of a print chamber to a secondary chamber. Negative pressure is applied to the secondary chamber and print chamber during motion of the platform, to reduce friction between the contents of the print chamber and sidewalls of the print chamber.
    Type: Grant
    Filed: April 29, 2019
    Date of Patent: September 19, 2023
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Wojciech Jerzy Krasowski, Arturo Garcia Gomez, Josep Maria Fernandez Sanjuan
  • Removing build material
    Patent number: 11485086
    Abstract: An example method to remove build material from a container is described. In that example a pulsed gas flow may be induced in a conduit to aspirate build material in pulses from the container.
    Type: Grant

  • COOLING UNIT WITH A SELF-LOCKING LATCH MECHANISM
    Publication number: 20220055306
    Abstract: A cooling unit can be coupled to a build unit of a 3D printing system. The cooling unit comprises a cooling unit opening which is arranged to face a build unit opening when the cooling unit is coupled to the build unit to enable transfer of content from the build unit to the cooling unit. The cooling unit further comprises a self-locking latch mechanism to couple the cooling unit to the build unit such that the cooling unit opening faces the build unit opening.

  • VIBRATION COOLING OF BUILD MATERIAL
    Publication number: 20210402690
    Abstract: There is disclosed a method of cooling a bed of build material 12, 14 generated by additive manufacture. A container 10 containing a bed of build material may be provided, the bed having a hot region relative to ambient temperature. The container may be vibrated to fluidize unfused build material 12 in the container so as to cause convection of the unfused build material to cool the hot region. There is also disclosed a method of cooling a bed of build material 12, 14 including vibration when the temperature of a hot region in the bed of build material is higher than an unpacking threshold. There is also disclosed a cooling apparatus for cooling a bed of build material by vibration.
