  • Patent number: 11945166
    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 on a rotor, the 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 via the rotor. The method can further include applying energy to the plurality of additively manufactured objects to cure a portion of each additively manufactured object while the plurality of additively manufactured objects are on the rotor.

  • Publication number: 20230137027
    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 receiving sensor data indicative of a cleaning status of the plurality of additively manufactured objects. The method can further include adjusting, based on the sensor data, an operational parameter that enhances removal of the excess material from the plurality of additively manufactured objects.

  • Publication number: 20230133005
    Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a system includes a plurality of containers configured to receive a plurality of additively manufactured object having excess material thereon. The system can include a rotor having a central shaft and a plurality of arms, each arm having a first end and a second end opposite the first end. The first end of each arm can be coupled to the central shaft and a second end of each arm can be coupled to a respective container of the plurality of containers. The system can also include an actuator configured to spin the rotor so as to remove the excess material from the plurality of additively manufactured objects. The system can further include at least one heat source carried on the rotor to heat the excess material to decrease a viscosity thereof.

  • Publication number: 20230134234
    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.
