Abstract

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.

First claim

What is claimed is:

1. A computer program product comprising non-transitory computer-executable code embodied in a non-transitory computer readable medium that, when executing on one or more computing devices, performs the steps of:
receiving a voice signal from an audio input coupled to an additive fabrication system including a three-dimensional printer;
processing 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 for the additive fabrication system, performing the steps of:
identifying a file corresponding to the object identifier that contains the three-dimensional model of the object;
scaling the three-dimensional model according to the at least one dimensional specification; and
creating one or more instructions for the additive fabrication system to fabricate the object from the scaled three-dimensional model.

2. The computer program product of claim 1 further computer-executable code that performs the step of authenticating a user based upon the voice signal.

3. The computer program product of claim 1 further computer-executable code that performs the step of executing the print command by initiating fabrication of the object on the three-dimensional printer based on the scaled three-dimensional model.

4. The computer program product of claim 1 further computer-executable code that performs the step of extracting a build material specification from the voice signal, the build material specification used to select a type of the build material for the three-dimensional printer.

5. The computer program product of claim 1 further computer-executable code that performs the steps of identifying an error in the voice signal and requesting a clarification for the error with spoken output through an audio output coupled to the additive fabrication system.

6. The computer program product of claim 5 wherein the error relates to the command.

7. The computer program product of claim 6 wherein the error includes an unrecognized command.

8. The computer program product of claim 6 wherein the error includes an incomplete command wherein at least one element is missing.

9. The computer program product of claim 8 wherein the incomplete command is an incomplete print command, and wherein the at least one element includes the object identifier or the dimensional specification.

10. The computer program product of claim 6 wherein the error occurs when the object identifier cannot be correlated to any printable object.

11. The computer program product of claim 6 wherein the error relates to the dimensional specification.
