    摘要： A jetted binder printing system includes a carrier substrate configured to travel along a longitudinal direction thereof, an adjustable binder printer configured to deliver an adjustable binder to the carrier substrate, a dispensing module located downstream from the adjustable binder printer on the longitudinal direction of the carrier substrate, the dispensing module including at least one powder container, the dispensing module being configured to dispense powder onto the carrier substrate, and a primary binder printer located downstream from the compaction module along the longitudinal direction of the carrier substrate. The primary binder printer includes a print head configured to print a primary binder on the dispensed powder according to a desired pattern. The primary binder is printed on a surface of the powder that is opposite a surface on which the adjustable binder is printed. The primary binder is printed to match the pattern of the adjustable binder.

    摘要： Containers for sealing and delivering consumable materials to an additive manufacturing system at an internal pressure below ambient atmospheric pressure, systems and methods for heating and reducing the moisture content of such consumable materials, and systems and methods of providing consumable materials to an additive manufacturing system in a vacuum environment are disclosed herein. An additive manufacturing system can include an environmental chamber configured to maintain a vacuum environment in an interior of the environmental chamber, a powder supply assembly situated in the environmental chamber, and a transfer system coupled to the environmental chamber and configured to receive a container containing a powder material and direct the powder material from the container to the powder supply assembly in the environmental chamber while maintaining the vacuum environment.

    摘要： Described is a powder dispensing apparatus for dispensing a powder, comprising: a dispensing chamber for dispensing a predetermined volume of powder to a receptacle; an inlet valve movable between a closed state and an open state to control ingress of powder into the dispensing chamber from a powder source; an outlet valve movable between a closed state and an open state to control egress of powder from the dispensing chamber to a receptacle. The inlet valve and outlet valve are individually actuated between the closed state and open state by a common removable handle. The inlet valve and outlet valve each comprise an interlock for receiving and engaging the handle. The interlock is configured to receive and release the handle when the respective valve is in the closed state and engage the handle so as to prevent removal of the handle when the respective valve is in the open state.
