Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a method includes receiving a plurality of additively manufactured objects having excess material thereon. The method can include removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects. The method can also include adjusting an environmental temperature while rotating the plurality of additively manufactured objects according to a dynamic temperature profile that facilitates removal of the excess material from the plurality of additively manufactured objects. The dynamic temperature profile can include (a) a first temperature configured to decrease a viscosity of the excess material, and (b) a second temperature configured to increase a stiffness of the plurality of additively manufactured objects.

Abstract: Systems and methods for designing additively manufactured objects are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, and determining a set of appliance parameters for a dental appliance configured to implement the treatment plan. The method can also include determining a set of manufacturing parameters for a fabrication system to be used to additively manufacture the dental appliance. The method can further include generating a 3D digital representation of an appliance geometry for the dental appliance. The appliance geometry can be configured to mitigate loss of fidelity at a target region of the dental appliance due to at least one manufacturing parameter of the fabrication system.

Abstract: A system includes a carrier film including an outer surface and an inner surface. The inner surface is configured to contact rollers. The system further includes a first blade configured to form a layer of resin on the outer surface of the carrier film. The system further includes a second blade configured to prevent printed features from contacting the first blade. The system further includes a build platform. A portion of the layer of resin is to be added to an object being formed on the build platform.
