Abstract: An end effector tool includes a fluid containing portion and an actuator. The fluid containing portion includes a distal wall located at a first distal end of the fluid containing portion and one or more sidewalls extending from the distal wall. The distal wall and the one or more sidewalls partially enclose an interior volume of the end effector tool. A fluid is disposed in the interior volume. The actuator is configured to apply energy to the fluid to change the fluid between a liquid state and a solid state. The fluid containing portion is to be placed over a dental product to cover the dental product with the fluid in the liquid state. The fluid is to secure the dental product responsive to the fluid being changed from the liquid state to the solid state.

Abstract: Systems and methods for manufacturing objects are provided herein. In some embodiments, a method for producing an additively manufactured object includes applying energy to a curable material according to a set of print parameters to form a cured material layer on a build platform or on an object on the build platform. The method can also include conveying remaining material away from the build platform. The method can further include detecting, via one or more sensors, that the remaining material includes a portion of the cured material layer that has separated from the build platform or from the object.
