Supply station for dispensing build material
A supply station for dispensing build material from a build material container is provided. The supply station includes a stationary support structure supporting a cylindrical cage along an axis, wherein the cylindrical cage is configured to be rotated in a first angular direction to dispense build material from the build material container.
1. A supply station for dispensing build material from a build material container, comprising:
a stationary support structure supporting a cylindrical cage along an axis, wherein the cylindrical cage is configured to releasably receive and retain the build material container and to be rotated in a first angular direction to rotate the build material container to dispense build material from the build material container,
wherein the cylindrical cage comprises:
a flat surface positioned upon an interior-facing curved surface of the cylindrical cage, the flat surface to align the build material container within the cylindrical cage; and
a latching mechanism extending from the flat surface, the latching mechanism to lock the build material container in place within the cylindrical cage.
2. The supply station of claim 1 , wherein the cylindrical cage is configured to be rotated in a second angular direction, opposite the first angular direction, to add build material to the build material container.
3. The supply station of claim 1 , comprising a valve mechanism configured to actuate a valve on the build material container.
4. The supply station of claim 1 , wherein the stationary support structure comprises a motor coupled to the cylindrical cage through a drive belt, wherein the drive belt passes through a bidirectional belt tensioner.
5. The supply station of claim 1 , wherein the latching mechanism extends a latch up from the flat surface in the cylindrical cage to engage indentations on the build material container.
6. The supply station of claim 1 , wherein the latching mechanism comprises a flag that is moved when a build material container is secured in place within the cylindrical cage.
7. The supply station of claim 6 , wherein the stationary support structure comprises a sensor to detect the flag.
8. The supply station of claim 1 , wherein the stationary support structure comprises a reader configured to couple to an information chip on the build material container.
9. The supply station of claim 1 , wherein the stationary support structure comprises a brake mechanism configured to engage openings along the cylindrical cage and hold the cylindrical cage in a base position.
10. The supply station of claim 1 , wherein the flat surface is configured to support a flat bottom of the build material container oriented along a horizontal axis of the cylindrical cage.
11. The supply station of claim 1 , wherein the cylindrical cage further comprises an actuating surface to actuate the latching mechanism in response to contact by the build material container.
12. The supply station of claim 11 , wherein the contact by the build material container on the actuating surface causes the latching mechanism to extend out from the flat surface to engage the build material container.
13. The supply station of claim 11 , wherein the cylindrical cage further comprises a release mechanism to retract the latching mechanism into the cylindrical cage under the flat surface.
14. The supply station of claim 1 , wherein the flat surface is configured to orient the build material container in a base position in the supply station, wherein the base position is to align a reading head of the supply station with an information chip mounted to the build material container.
