Laser marking of dental appliances

A method for inspecting a customized orthodontic aligner for manufacturing defects, the customized orthodontic aligner customized for a specific arch of a specific patient and a specific stage of orthodontic treatment, the method including obtaining images of the customized orthodontic aligner; identifying an identifier of the customized orthodontic aligner, determining a digital file based on the identifier, the digital file associated with the customized orthodontic aligner including a digital model of a mold used during manufacture of the customized orthodontic aligner, determining a intended property for the customized orthodontic aligner by digitally manipulating the digital model of the mold, determining an actual property of the customized orthodontic aligner from the images, determining whether there is a manufacturing defect in the customized orthodontic aligner by comparing the intended property with the actual property, outputting an output associated with the determination of whether there is a manufacturing defect.

Aligner image based quality control system

Mass-customized parts are identified by encoding part identification information into a multi-dimensional bar code, wherein mass-customization machinery, such as stereolithography apparatus, is used to make the parts with the multi-dimensional bar code embedded therein.

Identification of units in customized production

Systems and methods are disclosed for identifying a mass-customized part by encoding a part identification into a multi-dimensional bar code; and using a stereolithography apparatus (SLA) to make the part with multi-dimensional bar code embedded therein.
