摘要： A lamination fabricating method includes forming a powder layer including a powder for three-dimensional fabrication, applying a fabrication liquid to the powder layer, repeating the forming of the powder layer and the forming the powder layer to form a fabricated object, and forming a base layer prior to the forming of the powder layer. A powder filling rate of the base layer is higher than a powder filling rate of the powder layer.

摘要： A fabrication apparatus (10) includes a forming device (23; 24; 25; 26), an application device (22), an acquisition device (28), and circuitry (29). The forming device (23; 24; 25; 26) forms a layer containing powder (20). The application device (22) applies a fabrication liquid (21) to the layer formed by the forming device (23; 24; 25; 26). The acquisition device (28) acquires surface information of a surface of the layer. The circuitry (29) controls at least one of the forming device (23; 24; 25; 26) and the application device (22) to change at least one of an operation of the forming device (23; 24; 25; 26) and an operation of the application device (22) based on the surface information acquired by the acquisition device (28).

摘要： Systems, apparatus, computer-readable medium, and associated methods to monitor, analyze, and adjust at least one of 1) additive machine health and configuration or 2) build health and configuration are disclosed. An example apparatus includes an analytics processor, separate from and in a trusted relationship with an additive manufacturing machine building a part, to process, based on a trigger, data from monitoring of the additive manufacturing machine and the build of the part, the analytics processor including a hybrid model fusing additive process physics and data science to process the data to identify an abnormality in at least one of the build or the additive manufacturing machine and to adjust a configuration of the additive manufacturing machine during the build to address the abnormality.

摘要： Devices, systems, and methods for selectively sintering a powder layer in additive manufacturing processes to achieve a desired heat conductivity are disclosed. A method includes distributing a powder layer in a build chamber, selectively sintering the powder layer to form a plurality of sintered areas and a plurality of non-sintered areas based on a thermal model, and melting a subset of the plurality of sintered areas.
