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.

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 translation: 正畸器具可以包括弓丝和多个正畸托。 弓丝可以装配在人的嘴中并且包含多个公连接器。 每个正畸托架可以具有便于将正牙托架附接到单个牙齿的构造。 每个正畸托架可以允许一个公连接器以卡扣动作锁定到正畸托架中。 在插入正畸托架后，阳连接器可能无法相对于正畸托架滑动。 手动解锁动作可以允许公连接器脱离正畸托架。

Abstract: Methods, systems, and devices including a light guide tool for multi-axis additive manufacturing. The light guide tool includes a tubular light guide. The tubular light guide may be made from an optically transmissive material enclosed by one or more reflective side walls that are interposed between opposing optically transmissive ends. The light guide tool includes an optical coupling fixed to a first end of the optically transmissive ends of the tubular light guide. The optical coupling is configured to couple to a lens. The light guide tool includes a transparent non-stick coating. The transparent non-stick coating is adhered over a second end of the optically transmissive ends of the tubular light guide. The light guide tool includes a lens. The lens is coupled to the optical coupling and configured to emit a two-dimensional light pattern.

Abstract: A system for additively manufacturing a build part. The system includes a build platform configured for disposition within a resin tank, and a light source configured to cure a layer of resin. The layer of resin is disposed adjacent to a pre-cure build surface of the build part. The system also includes a constrained surface located between the build platform and the light source and configured to form a boundary for the layer of resin disposed between the constrained surface and the pre-cure build surface. The constrained surface is configured to vibrate to reduce a separation force required to separate the constrained surface from a post-cure build surface of the build part. The system also includes a vibratory source configured to vibrate the constrained surface.
