Embodiments of the invention provide a method and apparatus for manufacturing dental aligners. The system includes a workpiece introduction system having at least one workpiece preparation chamber. The system further has a mold manipulation system, having a mold introduction chamber, where a series of different molds may be introduced one after the other; a mold preparation chamber; a workpiece operation chamber; and a mold manipulator to move the mold between the mold introduction chamber, the mold preparation chamber, and the workpiece operation chamber; and a workpiece manipulator to move the workpiece between the workpiece preparation chamber and the workpiece operation chamber. In operation, the method includes steps of inserting a first workpiece into a workpiece preparation chamber; preparing the first workpiece for processing by subjecting the first workpiece to at least one preparation process; moving the first workpiece into a workpiece operation chamber; moving a first mold into a mold preparation chamber; preparing the first mold for processing by subjecting the first mold to at least one preparation process; moving the first mold into the workpiece operation chamber; moving the first mold and the first workpiece into cooperative engagement; subjecting the first workpiece to a vacuum on the side of the first workpiece facing the first mold; and repeating the above steps for a second workpiece and a second different mold.

What is claimed is: 1. A system for forming molded items from thermoplastic workpieces, comprising: a workpiece heating mechanism operable to heat a series of thermoplastic workpieces; a workpiece manipulator operable to move each workpiece sequentially from the heating mechanism to a workpiece ope
What is claimed is: 1. A system for forming molded items from thermoplastic workpieces, comprising: a workpiece heating mechanism operable to heat a series of thermoplastic workpieces; a workpiece manipulator operable to move each workpiece sequentially from the heating mechanism to a workpiece operation chamber; a plurality of molds, each single mold in the plurality of molds representing a unique shape; a plug in the workpiece operation chamber that is cooperatively engageable with each of the molds; and a mold manipulator operable to sequentially move the plurality of molds to the workpiece operation chamber for engagement with the plug therein; the workpiece manipulator and the mold manipulator being operable to position each workpiece in the workpiece operation chamber between a single mold and the plug so that each workpiece is formed into a uniquely shaped molded item through the cooperative engagement of the single mold and the plug. 2. The system of claim 1, further comprising a workpiece introduction system operable to introduce the series of workpieces sequentially into the workpiece heating mechanism. 3. The system of claim 2, wherein the workpiece introduction system is an inline system. 4. The system of claim 2, wherein the workpiece introduction system is a rotary turret system. 5. The system of claim 1, wherein the mold manipulator system is a rotary turret system. 6. The system of claim 2, wherein the workpiece introduction system includes a cutter that is operable to form the series of workpieces from a roll of thermoplastic material. 7. The system of claim 1, further comprising a mold preparation chamber, and wherein the mold manipulator system is operable to move each of the molds from the mold preparation chamber to the workpiece operation chamber. 8. The system of claim 7, wherein the mold preparation chamber includes the mold heating mechanism. 9. The system of claim 1, further comprising a laser-marking system operable to mark each molded item following its removal from the workpiece operation chamber. 10. The system of claim 1, further comprising a trimming system operable to trim each molded item following its removal from the workpiece operation chamber. 11. The system of claim 10, wherein the trimming system includes a multiple-axis CNC system. 12. The system of claim 1, wherein the molded items are uniquely shaped dental aligners. 13. The system of claim 1, wherein the plug is one of a series of plugs, each of which is configured for cooperation with a corresponding mold to ensure that the workpiece is pulled over the mold. 14. A system for forming molded items from thermoplastic workpieces, comprising: a workpiece heating mechanism operable to heat a series of thermoplastic workpieces; a workpiece operation chamber; a workpiece manipulator operable to move the series of workpieces sequentially from the heating mechanism to the workpiece operation chamber; a plurality of molds, each single mold in the plurality of molds representing a unique shape; and a mold manipulator operable to sequentially move the plurality of molds to the workpiece operation chamber; the workpiece manipulator and the mold manipulator being operable to deliver each single workpiece in the series of workpieces and each single mold in the plurality of molds substantially simultaneously to the workpiece operation chamber and to present the single workpiece to the single mold so that the single workpiece is formed into a uniquely shaped molded item. 15. The system of claim 14, further comprising a workpiece introduction system operable to introduce the series of workpieces sequentially into the workpiece heating mechanism. 16. The system of claim 15, wherein the workpiece introduction system is an inline system. 17. The system of claim 15, wherein the workpiece introduction system is a rotary turret system. 18. The system of claim 14, wherein the mold manipulator system is a rotary turret system. 19. The system of claim 15, wherein the workpiece introduction system includes a cutter that is operable to form the series of workpieces from a roll of thermoplastic material. 20. The system of claim 14, further comprising a mold preparation chamber, and wherein the mold manipulator system is operable to move each of the molds from the mold preparation chamber to the workpiece operation chamber. 21. The system of claim 20, wherein the mold preparation chamber includes the mold heating mechanism. 22. The system of claim 14, further comprising a laser-marking system operable to mark each molded item following its removal from the workpiece operation chamber. 23. The system of claim 14, further comprising a trimming system operable to trim each molded item following its removal from the workpiece operation chamber. 24. The system of claim 23, wherein the trimming system includes a multiple-axis CNC system. 25. The system of claim 14, wherein the molded items are uniquely shaped dental aligners. 26. The system of claim 14, wherein the workpiece operation chamber is operable to apply a vacuum to form the single workpiece into the unique mold item.
