  • Publication number: 20240227308
    Abstract: In an example, a method includes generating a plurality of calibration objects, each in a different region of a fabrication chamber of an additive manufacturing apparatus. In some examples the method further includes obtaining a measurement of a physical property of each calibration object. The method may include determining, by processing circuitry, calibrated print agent coverage amounts for each region based on the measured physical properties of the calibration objects wherein the calibrated print agent coverage amounts are to be used in a subsequent object generation operation.

  • Patent number: 11465204
    Abstract: A build material management system for a 3D printing system is described in which one or more input ports of a housing of the build material management system is to connect to one or more respective transportable containers. The transportable containers contain a volume of build material comprising 3D printed parts and a portion of non-fused build material. A pump also comprised within the housing is operable to provide a pressure differential across a conduit network of the build material management system. The pump is connected to the input port(s) by the conduit network. An air-flow caused through at least one of the one or more input ports is controlled by processing circuitry also comprised within the housing. The air-flow causes cooling within the respective transportable container. In one alternative, the housing comprises at least two input ports.

  • 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.

  • Patent number: 11110659
    Abstract: An additive-manufacturing build-material container comprises a reservoir to hold build material, a build-material outlet structure to allow build material to exit the reservoir through an outlet opening in a top portion of the reservoir, a longitudinal collection unit (313a) to collect build material from the bottom and guide the build material to the outlet opening at the top, and bottom-venting structure to admit vent gas into a bottom portion of the reservoir. The bottom-venting structure may include a vent tube to admit venting gas into the bottom portion of the reservoir. A concentric collection tube structure may be employed including the longitudinal collection tube nested within a vent tube (333A, 354A). The concentric collection tube structure may be mounted along the central axis of the reservoir.

  • Patent number: 11097480
    Abstract: There are disclosed methods and apparatuses for 3D printing post-processing. The methods and apparatuses provide a container for an additive manufacturing system, the container for receiving a build volume of fused and unfused build material. The container comprises a connector for connecting the container to a pressure source, and at least one air hole to allow passage of air into or out of the container. When the connector is connected to the pressure source, air flows through the container between the connector and the at least one air hole so as to remove unfused build material from the container and to help cool the volume of build material.
