Abstract

Methods for volume manufacturing of a plurality of unique items are provided. In some embodiments, a method includes: (a) initiating a predefined fabrication processing time period, (b) retrieving a fabrication data package containing manufacturing data, (c) verifying the fabrication data package for accuracy and completeness of the manufacturing data contained therein, and (d) performing at least one fabrication process in accordance with the manufacturing data contained in the fabrication data package. If the predefined fabrication time period has not expired, the method can include repeating (b) through (d). If the predefined fabrication time period has expired, the method can include generating a status report.

First claim

What is claimed is:

1. A method for volume manufacturing of a plurality of unique items, the method comprising:
(a) initiating a predefined fabrication processing time period;
(b) upon initiating the predefined fabrication processing time period, operating a central manufacturing processor of a fabrication system in accordance with executable program instructions to retrieve a fabrication data package containing manufacturing data;
(c) operating the central manufacturing processor in accordance with the executable program instructions to verify the fabrication data package for accuracy and completeness of the manufacturing data contained therein;
(d) operating at least one fabrication terminal of the fabrication system to receive the verified fabrication data package from the central manufacturing processor and to perform at least one fabrication process in accordance with the manufacturing data contained in the fabrication data package;
(e) if the predefined fabrication processing time period has not expired,
determining a process load associated with at least one additional fabrication data package, and
repeating (b) through (d) for the at least one additional fabrication data package if the process load of the at least one additional fabrication data package is less than a predetermined process load of the fabrication system; and

(f) if the predefined fabrication processing time period has expired, operating the central manufacturing processor in accordance with the executable program instructions to generate a status report.

2. The method of claim 1 , wherein the fabrication data package is retrieved via a data network.

3. The method of claim 1 , wherein the fabrication data package is retrieved from a remote terminal.

4. The method of claim 3 , further comprising operating the central manufacturing processor in accordance with the executable program instructions to output periodic fabrication process status update reports to the remote terminal.

5. The method of claim 1 , wherein the plurality of unique items are dental aligners, and wherein the manufacturing data includes a three-dimensional data representation of a patient's teeth for each of a plurality of treatment stages for the patient.

6. The method of claim 5 , wherein operating the central manufacturing processor in accordance with the executable program instructions to verify the fabrication data package for accuracy and completeness of the manufacturing data contained therein includes determining whether the fabrication data package is missing data for any of the treatment stages.

7. The method of claim 6 , wherein if the fabrication data package is missing data for at least one treatment stage, the method further comprises requesting the missing data before performing the at least one fabrication process.

8. The method of claim 1 , further comprising operating the central manufacturing processor in accordance with the executable program instructions to generate a message upon completion of the verification.

9. The method of claim 8 , wherein the fabrication data package is retrieved from a remote terminal, and wherein the generated message is transmitted to the remote terminal.

10. The method of claim 1 , further comprising operating the central manufacturing processor in accordance with the executable program instructions to generate input data for the fabrication terminal to perform a fabrication process subsequent to the at least one fabrication process.

11. The method of claim 1 , further comprising operating the central manufacturing processor in accordance with the executable program instructions to detect an error condition associated with the fabrication data package, and to transmit a report including the error condition to a remote processor.

12. The method of claim 11 , wherein the remote terminal is operable to modify the fabrication data package to address the error condition and to communicate a modified fabrication data package to the central manufacturing processor.

13. The method of claim 1 , wherein the at least one fabrication process comprises generating a tray data file based on the manufacturing data, wherein the tray data file includes layout information indicating a spacing and an orientation for each of the plurality of unique items on a tray.

14. The method of claim 1 , wherein the at least one fabrication process comprises manufacturing the plurality of unique items via a rapid prototyping process.

15. The method of claim 1 , wherein the predetermined process load of the fabrication system is based on an operational status of the at least one fabrication terminal in performing the at least one fabrication process.

16. The method of claim 15 , wherein the at least one fabrication process comprises:
generating three-dimensional object data based on the manufacturing data contained in the fabrication data package, and
causing a manufacturing machine to fabricate a unique item according to the three-dimensional object data.

17. The method of claim 16 , wherein the at least one fabrication process comprises converting the three-dimensional object data into a format executable by the manufacturing machine.

18. The method of claim 1 , wherein if the process load of the at least one additional fabrication data package is not less than the predetermined process load of the fabrication system, the method comprises timing out for a predetermined period before repeating (b) through (d) for the at least one additional fabrication data package.

19. The method of claim 1 , wherein the at least one fabrication terminal comprises a plurality of fabrication terminals, and wherein the method further comprises:
parsing the fabrication data package into a plurality of data batches, and
transmitting each data batch to one of the plurality of fabrication terminals.

20. The method of claim 19 , further comprising monitoring an operational status of each of the plurality of fabrication terminals.
