Abstract: An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.

Abstract: A sliding window is used in a projection-based stereolithographic process to more quickly deliver uncured resin after each curing pass. The sliding window may be configured in different patterns, and includes features for delivering resin and exposing resin to curing radiation. The window screen divides the stereolithographic building area divided into two portions, a light exposure portion for resin curing and a liquid resin refilling portion. The light exposure portion is used to selectively solidify liquid resin, while the liquid resin refilling portion is used to quickly refill liquid resin in order to build additional layers. During the layer fabrication process, a mask image is projected to the tank; however, the projection light only passes through the light exposure portion of the window screen.
