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 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.

Abstract: According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.
