Abstract: Systems for fabricating orthodontic appliances are provided. In some embodiments, a system includes a build platform configured to receive a polymerizable composition, the polymerizable composition including a first polymerizable component and a second polymerizable component, the polymerizable composition characterized by an initial ratio of the first polymerizable component to the second polymerizable component. The system can also include a light source configured to form a portion of an orthodontic appliance from the polymerizable composition by: forming a first region by exposing the polymerizable composition to radiation, where the first region includes a first ratio of the first polymerizable component to the second polymerizable component, the first ratio being different from the initial ratio; and forming a second region, where the second region includes a second ratio of the first polymerizable component to the second polymerizable component, the second ratio being different from the initial ratio and the first ratio.

Abstract: Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a digital data set representing an object, and applying energy to a curable material based on the digital data set to form the object. The object can include at least two object portions formed from the curable material using different energy application parameters. The method can further include removing residual curable material from the object. A different amount of the residual curable material can be removed from each of the at least two object portions. After the residual curable material is removed, the at least two object portions can each have different material properties.

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.

Abstract: A system includes a partial enclosure configured to hold resin. The system further includes one or more structures configured to at least partially cover the resin. The one or more structures are configured to prevent evaporation of the resin. The system further includes a build platform configured to support an object that is being formed from layers of the resin. A first blade is configured to provide the layers of the resin to form the object on the build platform.

Abstract: Provided herein are methods of obtaining good photocured-ink adhesion to low surface energy materials. The methods have greatly improved adhesion of photocured ink on low surface energy materials, including those that are subjected to high humidity or wet environments. The methods take into account the glass transition temperature (Tg) of the materials and the onset for the glass transition temperature, including ink applied to an exposed surface of the material at an elevated temperature that is close to the Tg of the material. The ink is allowed to sit briefly or soak, such as for more than 1 second, before the ink is cured. The ink may be photocured. Furthermore, the methods do not require solvents or surface treatment, including plasma or corona treatments, to obtain good ink adhesion.

Abstract: A method of three-dimensional (3D) printing includes heating a photo-curable material and extruding the photo-curable material from a nozzle to form a first layer of an object according to a digital file, wherein the first layer has a first shape specified by the digital file, and wherein the first shape has a first minimum line width based on a diameter of the nozzle. The method further includes directing a light beam onto the first layer according to the digital file or an additional digital file to cure a portion of the first layer, wherein the cured portion of the first layer has a second shape, wherein the second shape may comprise features that are smaller than the first shape.
