The material may be a sacrificial material that may be later removed. The orthodontic appliance may be an archwire or a self-ligating orthodontic bracket having one or more layered structures formed by plating patterns of the material. Plating may include plating patterns of materials so as to form a movable member in place relative to a bracket body.
