Abstract: Implementations describe systems and methods for machine based defect detection of three-dimensional (3D) printed objects. A method of one embodiment of the disclosure includes providing a first illumination of a 3D printed object using a first light source arrangement. A plurality of images of the 3D printed object are then generated using one or more imaging devices. Each image may depict a distinct region of the 3D printed object. The plurality of images may then be processed by a processing device using a machine learning model trained to identify one or more types of manufacturing defects of a 3D printing process. The machine learning model may provide a probability that an image contains a manufacturing defect. The processing device may then determine, without user input, whether the 3D printed object contains one or more manufacturing defects based on the results provided by the machine learning model.

Abstract: A manufacturing system, comprises one or more image capture devices configured to generate one or more images of a three-dimensional (3D) printed orthodontic appliance associated with a dental arch of a patient. The manufacturing system further comprises a computing device configured to: receive the one or more images of the 3D printed orthodontic appliance; process the one or more images of the 3D printed orthodontic appliance to determine probabilities of one or more types of manufacturing defects for the 3D printed orthodontic appliance; and determine whether to use the 3D printed orthodontic appliance for orthodontic treatment of the patient based on the probabilities of the one or more types of manufacturing defects.

Abstract: A system includes a mold of a dental arch of a patient. The mold includes teeth extending from a first distal end of the dental arch to a second distal end of the dental arch. An orthodontic aligner is to be formed over the teeth of the mold. The teeth of the mold are shaped to correspond to tooth-receiving cavities of the orthodontic aligner. The system includes a pre-fabricated attachment that includes a traceability component configured to be used to determine one or more identifiers corresponding to the mold. The pre-fabricated attachment further includes a handling component configured to be secured by a robot or person to transport the mold and the pre-fabricated attachment during production of the orthodontic aligner.

Abstract: A method includes obtaining image(s) of a dental device, determining file(s) including at least one of a first model of the dental device or a second model of a mold, determining an intended property for the dental device based on at least one of the first model or the second model, and determining an actual property of the dental device from the image(s). The method further includes determining whether a cutline variation, an arch variation, and/or a bend of the dental device is detected between the dental device and the first model and/or the second model by comparing the intended property with the actual property. The method further includes determining whether there is a possible defect in the dental device based on whether the cutline variation exceeds a cutline variation threshold, the arch variation exceeds an arch variation threshold, and/or the bend exceeds a bend threshold.

Abstract: A method of manufacturing and analyzing a quality of an orthodontic aligner is described. An orthodontic aligner is manufactured by printing a mold associated with a dental arch of a patient based on a digital model of the mold, forming an orthodontic aligner over the mold, and trimming the orthodontic aligner. A quality of the orthodontic aligner is then assessed by imaging the orthodontic aligner to generate a first digital representation of the orthodontic aligner, comparing the first digital representation of the orthodontic aligner to a digital file associated with the orthodontic aligner, determining whether a cutline variation is detected between the orthodontic aligner and the digital file, and determining whether there is a manufacturing defect of the orthodontic aligner based on whether the cutline variation exceeds a cutline variation threshold.

Abstract: A system for inspecting a customized dental device associated with a dental application for manufacturing defects is disclosed. The system obtains images of the customized device and identifies an identifier of the customized device. The system determines a digital file associated with the customized device based on the identifier, the digital file including a first digital model of the customized device and/or a second digital model of a mold used during manufacture of the customized device. The system determines an intended property for the customized device based on at least one of the first digital model or the second digital model, determines an actual property of the customized device from the images, determines whether there is a manufacturing defect in the customized device by comparing the intended property for the customized device with the actual property of the customized device, and outputs an output associated with the determination.
