| 20080292741 | METHOD AND APPARATUS FOR MASS CUSTOMIZED MANUFACTURING - 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. | 11-27-2008 |
| 20080300824 | SYSTEM AND METHOD FOR SELECTING A LOCATION FOR MARKING PLACEMENT - A system and associated method for selecting or creating an area which meets meet a set of marking criteria, for example, corresponding to a minimum surface area; a maximum slope angle; and a minimum deviation from a specified height. A marking station is directed to mark the selected area that meets the marking criteria. | 12-04-2008 |
| 20100006640 | SYSTEM FOR PROCESSING MASS-FABRICATED ITEMS WITH THREE-DIMENSIONAL CODES - In the processing of mass-produced items that include a three-dimensional code formed therein, a system is provided for automating certain post-manufacturing processing steps. The system includes a printing mechanism that applies ink to the three-dimensional code to form an optically-readable code; a code-reading mechanism that reads the optically readable code and transmits a signal indicative of the code to a database that may be employed for tracking the processed items; and a transport mechanism that moves the items from the printing mechanism to the code-reading mechanism. In one embodiment, the system also includes a liquid agent application mechanism that applies a liquid agent to the items after the optically-readable code is formed. The transport mechanism includes a plurality of pallets on which the items are placed for processing, and that is operable to move the pallets sequentially to the several processing mechanisms. | 01-14-2010 |
| 20100173266 | SYSTEM AND METHOD FOR AUTOMATED GENERATING OF A CUTTING CURVE ON A SURFACE - In accordance with various aspects of the present invention, a system and method for automated generating of a cutting curve on a surface is provided. In accordance with an exemplary embodiment, a computer-implemented method for automated generating of a cutting curve on a gingival surface to facilitate cutting of an aligner material comprises the defining of initial gingival curves along the line around a tooth (LAT) on a patient's jaw, including within an interproximal area between teeth. The initial gingival curves are replaced with a modified, dynamic cutting curve comprising an offset adjustment configured to minimize weakening of a region of the aligner material within the interproximal area. This process for generating a modified, dynamic cutting curve within an interproximal area can be suitably applied or continued for each of other the teeth and interproximal areas between those teeth to define a complete dynamic cutting curve. The resulting complete dynamic cutting curve can then be output for conversion into machine executable code to facilitate cutting of the aligner material. | 07-08-2010 |
