    Abstract: Provided herein are systems and processes to control multiple temperatures in additive manufacturing. Such temperature control adjusts polymer properties and facilitates processing of materials to form 3D objects. The systems and processed disclosed herein also facilitate the processing of typically difficult-to-process materials and deliver such materials to a photocuring zone configured to photopolymerize materials into 3 dimensional objects with a layer-by-layer process. Such processes can include the steps of heating a resin to a flowable temperature, applying the resin to a carrier, cooling the film to increase viscosity or to solidify the resin, and applying the film containing the resin onto an area being printed, then photocuring the film. Also provided herein are resins and related polymer materials having properties that are tunable with exposure to more than one temperature zone. The formed polymers can include multiple regions of polymer material, each independently having distinct properties. Processes and systems are also provided herein that are configured to produce polymeric materials having multiple regions with distinct properties from a single-component formulation.

    Abstract: Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment. The cover can include a sleeve that covers a handle portion of the scanning device to prevent contamination of the handle from a user's hand or glove. The cover and sleeve may both be formed of the same flexible material, or the cover may be rigid to maintain the window in a fixed position and the sleeve may be flexible to allow a user to activate a button or touchpad on the handle. An interface region between the cover and sleeve may provide a hermetic seal. The window may include a nanostructured antireflective material to limit internal reflections.

    Abstract: Systems, methods, devices, and apparatus for positioning a patient's mandible in response to sleep apnea status are provided herein. In one aspect, a system for monitoring and treating sleep apnea in a patient comprises one or more sensors configured to monitor the patient for symptoms associated with sleep apnea; an intraoral appliance worn by the patient, one or more processors, and memory comprising instructions executable by the one or more processors to cause the one or more processors to: receive a set of sensor data from the one or more sensors, detect, using a machine learning algorithm, onset of a sleep apnea event based on the set of sensor data, and transmit a control signal to the intraoral appliance to cause the intraoral appliance to displace a lower jaw of the patient from a first position to a second position in order to treat the sleep apnea event.
