Voice-controlled three-dimensional fabrication system
An additive three-dimensional fabrication system includes voice control for user interaction. This voice-controlled interface can enable a variety of voice-controlled functions and operations, while supporting interactions specific to consumer-oriented fabrication processes.
1. A device comprising:
an additive fabrication system, wherein the additive fabrication system includes a three-dimensional printer;
an audio input coupled to the additive fabrication system;
an audio output coupled to the additive fabrication system; and
a processor configured to receive a voice signal from the audio input, process the voice signal to extract a command for the additive fabrication system, an object identifier that specifies a three-dimensional model of an object, and at least one dimensional specification including a physical dimension specifying one or more of a height, a width, and a depth of a fabricated object fabricated by the three-dimensional printer based upon the three-dimensional model specified by the object identifier, and when the command includes a print command, to cause the additive fabrication system to execute the print command based upon the object identifier and the dimensional specification.
2. The device of claim 1 wherein the processor is further configured to identify an error in the voice signal, and to request a clarification for the error with spoken output through the audio output.
3. The device of claim 2 wherein the error relates to the command.
4. The device of claim 3 wherein the error includes an unrecognized command.
5. The device of claim 3 wherein the error includes an incomplete command wherein at least one element is missing.
6. The device of claim 5 wherein the incomplete command is an incomplete print command, and wherein the at least one element includes the object identifier or the dimensional specification.
7. The device of claim 3 wherein the error occurs when the object identifier cannot be correlated to any printable object.
8. The device of claim 3 wherein the error occurs because the object identifier requires disambiguation to resolve to a unique printable object.
9. The device of claim 3 wherein the error relates to the dimensional specification.
10. The device of claim 9 wherein the dimensional specification exceeds a build volume of the additive fabrication system.
11. The device of claim 9 wherein the dimensional specification exceeds a dimensional processing capability of the additive fabrication system.
12. The device of claim 1 wherein the print command includes an instruction to fabricate the object with the three-dimensional printer.
13. The device of claim 1 wherein the object identifier includes at least one of a file name and file metadata.
14. The device of claim 1 wherein the dimensional specification includes at least one of a scale of an object and a dimension of an object, the dimension of the object further including at least one of height, width, and depth.
15. The device of claim 1 wherein the processor is further configured to extract a build material specification from the voice signal, the build material specification used to select a type of the build material for the additive fabrication system.
16. The device of claim 15 wherein the build material specification includes a color specification used to select a color of the build material.
17. The device of claim 15 wherein the type is one of a plurality of different types of build material available to the additive fabrication system.
18. The device of claim 15 wherein the additive fabrication system is configured to detect the type of the build material using at least one sensor, and wherein the processor is configured to confirm that the actual build material corresponds to the type of the build material corresponds to the build material specification.
19. The device of claim 1 wherein the processor is further configured to extract one or more print parameters from the voice signal.
20. The device of claim 19 wherein the one or more print parameters include an infill percentage.
21. The device of claim 19 wherein the one or more print parameters include a relative print speed.
22. The device of claim 1 wherein the processor is further configured to provide a status update as spoken output through the audio output.
23. The device of claim 22 wherein the status update relates to completion of a build.
24. The device of claim 22 wherein the status update relates to availability of the additive fabrication system.
25. The device of claim 22 wherein the status update relates to instrumentation of the additive fabrication system.
26. The device of claim 1 wherein the processor is further configured to transmit the voice signal in digital form to a remote processing facility for speech recognition.
27. The device of claim 26 wherein the remote processing facility returns instructions to additive fabrication system.
28. The device of claim 26 wherein the remote processing facility returns text to the processor, the processor further configured to parse the text into one or more commands for the additive fabrication system.
29. The device of claim 1 wherein the audio input includes a microphone.
30. The device of claim 1 wherein the audio output includes a speaker.
