Abstract

Three-dimensional fabrication resources are improved by adding networking capabilities to three-dimensional printers and providing a variety of tools for networked use of three-dimensional printers. Web-based servers or the like can provide a single point of access for remote users to manage access to distributed content on one hand, and to manage use of distributed fabrication resources on the other.

Claims

1. A device comprising:

a three-dimensional printer including a build volume;

a network interface coupled to a data network;

a video camera positioned to capture video of the build volume from a point of view; and

a processor configured to receive a three-dimensional model through the network interface, and to control operation of the three-dimensional printer to fabricate the three-dimensional model as an object within the build volume of the three-dimensional printer, the processor further configured to provide a user interface to a remote user accessing the device through the network interface, and to present in the user interface an image of the build volume from the camera and a two-dimensional projection of the three-dimensional model from the point of view of the video camera.

2. The device of claim 1 wherein the two-dimensional projection is obtained from a three-dimensional scanner coupled to the processor.

3. The device of claim 1 wherein the two-dimensional projection is simulated based upon operation of the three-dimensional printer.

4. The device of claim 3 wherein the processor is configured to monitor operation of the three-dimensional printer based upon a comparison of the two-dimensional projection with the image of the build volume.

5. The device of claim 1 wherein the two-dimensional projection is dynamically updated to correspond to a state of physical completion of the object.

6. The device of claim 1 wherein the two-dimensional projection is a video image from the video camera.

7. The device of claim 1 wherein the user interface provides at least one control for manual operation of the three-dimensional printer by the remote user.

8. The device of claim 1 wherein the processor is configured to provide credential-based access to the user interface.

9. The device of claim 1 wherein the user interface provides status information for the three-dimensional printer.

10. The device of claim 1 wherein the user interface provides status information for a build process executing on the three-dimensional printer.

11. The device of claim 1 wherein the user interface displays a two-dimensional tool path for the three-dimensional printer, the two-dimensional tool path corresponding to a current layer of the object during a fabrication of the object by the three-dimensional printer.

12. The device of claim 1 wherein the user interface supports remote access for technical support during local operation of the three-dimensional printer.

13. The device of claim 1 wherein the processor is configured to fabricate a test object, capture an image of the test object, and compare the image to the test object to validate operation of the three-dimensional printer.

14. The device of claim 1 wherein the user interface includes at least one control to capture a frame of data from the video camera as a video image and to transmit the video image to a remote location through the data network.

15. The device of claim 14 wherein the remote location is a social networking site.

16. The device of claim 14 wherein the device is configured to transmit the video image in an electronic mail communication.

17. The device of claim 1 wherein the user interface includes at least one control to capture a stop-motion animation of a fabrication of the object using the video camera.

18. The device of claim 1 wherein the processor is configured to couple the three-dimensional printer in a communicating relationship with a remote print server through the data network.

19. A method comprising:

providing a three-dimensional printer including a build volume, a network interface coupled to a data network, and a video camera positioned to capture video of the build volume from a point of view;

receiving a three-dimensional model through the network interface;

fabricating the three-dimensional model as an object within the build volume of the three-dimensional printer; and

providing a user interface to a remote user accessing the device through the network interface, wherein the user interface presents an image of the build volume from the camera and a two-dimensional projection of the three-dimensional model from the point of view of the video camera.

20. The method of claim 19 further comprising transmitting status information over the data network upon completion of the object.

21. The method of claim 20 wherein the status information includes data presented through the user interface.

22. The method of claim 20 wherein the status information includes a digital image from the video camera.

23. The method of claim 22 wherein the digital image is transmitted with an electronic mail communication confirming completion of the object.
