Arrangement and method for manufacturing a plurality of orthodontic appliances

1. An arrangement for manufacturing a plurality of orthodontic appliances in parallel, comprising

an additive printing machine comprising a build platform and configured for additively manufacturing a plurality of teeth models or the plurality of orthodontic appliances in parallel, and

a plurality of plates each configured for teeth model printing or orthodontic appliance printing, respectively, by the additive printing machine, whereby each plate comprises a unique machine-readable identifier and each plate is detachable and precisely fixed to the build platform,

whereby at least one of each plate and the build platform comprises at least one of a magnetic device or locking device for detachably and precisely fixing the plate to the build platform and/or whereby the build platform comprises negative forms for positioning a respective plate therein.

2. The arrangement according to claim 1 , whereby the additive printing machine is configured for additively manufacturing the plurality of teeth models and comprising a thermoforming machine configured for thermoforming a thermoformable material over the plurality of teeth models.

3. The arrangement according to claim 1 , whereby the plates are arranged on the build platform of the additive printing machine in a regular pattern.

4. The arrangement according to claim 1 , whereby the identifier comprises at least one of a RFID, a QR barcode, a bar code, or a magnetic stripe.

5. The arrangement according to claim 1 , whereby the identifier is arranged on the teeth model or orthodontic appliance, respectively on the plate and/or whereby additive printing takes place on the plate.

6. The arrangement according to claim 1 , whereby the identifier comprises at least one of a RFID or a magnetic stripe and whereby the at least one of the RFID or the magnetic stripe is provided within the plate.

7. The arrangement according to claim 1 , comprising a detection device configured for detecting the identifier and a position of each plate in respect to the build platform and whereby the additive printing machine is configured to controlling printing in respect to the detected identifier and position.

8. The arrangement according to claim 1 , whereby the additive printing machine comprises one of a 3-dimensional, 3D, printing machine, a selective laser melting, SLM, printing machine, a selective laser sintering, SLS, machine or a stereolithography, SLA, printing machine.

9. The arrangement according to claim 1 , whereby each plate comprises a positioning element configured for precisely fixating the plate to the build platform.

10. The arrangement according to claim 9 , whereby the positioning element comprises a plurality of position holes, notches and/or outside forms of the plate.

11. The arrangement according to claim 9 , comprising at least one of a laser marking machine or a CNC machine comprising a connector base configured to precisely position at least one of the plates via the respective positioning element.

12. A method for manufacturing a plurality of orthodontic appliances in parallel, comprising the steps of:

providing a plurality of plates each configured for teeth model printing or orthodontic appliance printing by an additive printing machine and each plate comprising a unique machine-readable identifier,

detachably and precisely fixing the plates onto a build platform of the additive printing machine, and

manufacturing a plurality of teeth models or the plurality of orthodontic appliances, respectively, on the plates in parallel by the additive printing machine, whereby

at least one of each plate and the build platform comprises at least one of a magnetic device or locking device for detachably and precisely fixing the plate to the build platform and/or whereby the build platform comprises negative forms for positioning a respective plate therein.

13. The method according to claim 12 , whereby the plurality of plates are each configured for teeth model printing by the additive printing machine, and comprising the step of:

thermoforming a thermoformable material over the teeth models by a thermoforming machine.

14. The method according to claim 12 , comprising the step of:

positioning at least one of the plates with a positioning element of the plate into a connector base of at least one a laser marking machine or a CNC machine for subsequent processing the plate according to the detected identifier in the respective machine,

positioning at least one of the plates with the positioning element into the connector base of a thermoforming machine for subsequent processing the plate according to the detected identifier.

15. The method according to claim 12 , comprising the step of:

activating a magnetic device for locking the plates on the build platform.

16. The method according to claim 12 , comprising the steps of:

detecting the identifier and a position of each plate in respect to the build platform and controlling printing in respect to the detected identifier and position.
