    摘要： A method for managing the temperature of three-dimensional object (102) during additive manufacturing includes depositing material on a partial fabrication of the three-dimensional object, determining thermal properties of the three-dimensional object after depositing the material, and controlling cooling of the object according to said thermal properties. In some examples, the determining of the thermal properties includes determining a temperature variation across the object and controlling position-dependent cooling of the object in a feedback arrangement. Resulting uniform temperature of the object under fabrication can improve dimensional accuracy and material properties of the object.

    摘要： A manufacturing method includes using an additive manufacturing process to form a first object. The first object includes layers, among which is a first layer that comprises a first material and a second material. The first material surrounds the second material within the first layer. Both materials are solids that transition into liquids at corresponding first and second temperatures, the first temperature being lower than the second temperature. The method includes, after having formed the first object, exposing the first object to a temperature that is between the first temperature and the second temperature such that the first material melts, thereby leaving behind a second object, the second object comprising the second material.

    摘要： A method for additive manufacturing includes forming an object including depositing a first material including a first coloring component and a second material including a second coloring component, wherein both the first material and the second material further include a corresponding fluorescent component, scanning the object, including causing an emission of an optical signal from the object, wherein the emission of the optical signal is caused at least in part by an emission from the fluorescent components interacting with the first coloring component and the second coloring component as it passes from the fluorescent components to the surface of the object, sensing the emission of the optical signal, and determining presence of the first material and the second material based at least in part on the sensed emission of the optical signal.

    摘要： An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.
