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.
