Build material source container

1. A build material source container for use in a material management station of a three dimensional, 3D, printer, the source container comprising:

an external reinforcement structure forming a substantially enclosed space for holding build material, the reinforcement structure being formed of an electrically non-conductive material and having a top and a bottom;

an outlet structure having an aperture for build material ingress into and egress from the substantially enclosed space, wherein the outlet structure is connectable to a connection unit for extracting build material from the source container via air pressure, and wherein the outlet structure is located at the top of the reinforcement structure; and

an internal tube extending into the substantially enclosed space from the aperture of the outlet structure to the bottom of the reinforcement structure, the internal tube including electrically conductive material that is in electrical communication with the outlet structure;

wherein the outlet structure comprises an adapter to couple to a first end portion of the connection unit, the adapter further comprising a data interface to connect and provide transport data to a corresponding data interface on the connection unit; and

wherein the adapter when connected to the connection unit forms part of a static electricity discharge path that includes the internal tube;

wherein an interconnector further secures the adapter to the build material source container; or

wherein the interconnector connects the adapter to the first end portion of the connection unit.

2. The build material source container of claim 1 , wherein the adapter comprises at least one electrically conductive interconnector to electrically couple the outlet structure of the build material source container to an electrically conductive portion of the connection unit.

3. The build material source container of claim 1 ,

wherein the outlet structure is to contact an electrically conductive portion of the connection unit to electrically couple the build material source container to Earth.

4. The build material source container of claim 1 , wherein the adapter of the build material source container comprises at least one first conductive interconnector for connecting to a respective at least one second conductive interconnector arranged at an end portion of the connection unit.

5. The build material source container of claim 4 , wherein at least one of the first and second conductive interconnectors is magnetic to magnetically couple to the other of the first and second conductive interconnectors to connect the adapter to the end portion of the connection unit.

6. The build material source container of claim 1 , wherein the data interface is electrically isolated from the outlet structure.

7. The build material source container of claim 1 , wherein at least a part of the electrically conductive material comprises a conductive plastic.

8. The build material source container of claim 1 , wherein the electrically conductive material comprises a conductive plastic, a conductive film or coating, a wire or other circuitry applied to a component of the build material source container.

9. The build material source container of claim 8 , wherein at least part of the electrically conductive material extends along at least a portion of the outlet structure that defines a build material outflow path of the container.

10. The build material source container of claim 9 , wherein the internal tube is to collect build material from a portion of the container distal to the aperture.

11. The build material source container of claim 1 , wherein the bottom of the reinforcement structure includes a funnel shape formed by included converging walls.

12. The build material source container of claim 11 , wherein the internal tube comprises an end portion in contact with the funnel shaped bottom, the end portion including a suction opening through which build material is to enter into the internal tube from the external reinforcement structure.

13. The build material source container of claim 1 , wherein the outlet structure is formed from an electrically conductive material and is connectable to Earth to discharge static electricity generated within the build material source container.
