Abstract: Methods and systems for generating support structures for additively manufactured objects are described herein. In some embodiments, a method includes receiving a digital representation of a dental appliance configured to implement a treatment stage of a treatment plan for a patient's teeth. The method can include generating a support structure arrangement configured to support the dental appliance during an additive manufacturing process. The support structure arrangement can be generated using a machine learning model. The machine learning model can be trained on a training data set including appliance data representing geometries of a plurality of dental appliances, support structure data representing geometries of a plurality of support structure arrangements, and outcome data representing outcomes of the additive manufacturing process for the plurality of dental appliances with the respective support structure arrangements.

Abstract: Methods and systems for processing additively manufactured objects are provided. In some embodiments, a method includes receiving an object fabricated using an additive manufacturing process, the object including a functional portion and a plurality of support structures connecting the functional portion to a build platform. The method can include cooling the plurality of support structures using a coolant. The method can further include fracturing the plurality of support structures to separate the functional portion of the object from the build platform.
