Abstract: Systems and methods for additive manufacturing are provided. In some embodiments, a method for additive manufacturing includes forming a portion of an additively manufactured object within a reservoir of curable material by scanning a plurality of energy beams of a plurality of energy sources through a plurality of respective scanning regions in the curable material. The scanning regions can overlap at one or more object locations, such that a combined energy dosage delivered to the one or more object locations by two or more of the energy beams is greater than or equal to a threshold dosage for solidifying the curable material. The method can further include advancing the reservoir of curable material relative to the energy sources. The forming and advancing processes can be repeated to fabricate the additively manufactured object.

Abstract: Embodiments relate to an aligner breakage solution that tests damage to an aligner using machine learning. A method includes of training a machine learning model to predict damage to an orthodontic aligner includes gathering a training dataset comprising digital designs for a plurality of orthodontic aligners, wherein each digital design is associated with a respective orthodontic aligner of the plurality of orthodontic aligners, and wherein each digital design comprises metadata indicating whether the associated respective orthodontic aligner was damaged during manufacturing of the associated respective orthodontic aligner. The method further includes training the machine learning model using the training dataset, wherein the machine learning model is trained to process data from a digital design for an orthodontic aligner and to output a probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner.

Abstract: Embodiments relate to an aligner breakage solution that tests progressive damage to an aligner. A method includes gathering a digital model representing an aligner for a dental arch of a patient, and simulating progressive damage to the aligner. Simulating progressive damage for a region of the aligner comprises simulating, using at least the digital model, a sequence of loads on the aligner, determining an amount of damage to the region of the aligner for each load, and after each simulation of a load on the aligner, updating the digital model based on the amount of damage to the region of the aligner. The method further includes determining whether a damage criterion is satisfied for at least one region of the aligner and determining whether to implement one or more corrective actions for the aligner.
