    Abstract: A method for the additive manufacturing of an object and a system for manufacturing an object. The method includes depositing a second foil sheet onto the first foil sheet, wherein the first foil sheet and the second foil sheet each comprise a structural layer, forming a layer stack comprising the first foil sheet and the second foil sheet, the layer stack comprising an object section and at least one support section configured to enclose the object section in the layer stack, and applying at least one of heat or pressure to opposite sides of the layer stack with a first plate and a second plate, wherein applying the at least one of heat or pressure increases the temperature of the layer stack to a temperature lower than the melting temperature of the structural layer, and the at least one of heat or pressure bonds the first foil sheet to the second foil sheet in the layer stack, the first plate and the second plate are in contact with the at least one support section, and the at least one support section is configured to conduct the at least one of heat or pressure through the layer stack to the object section.

    Abstract: Disclosed are selective deposition based additive manufacturing systems (10) and methods for printing a 3D part. Layers of a powder material (22) are developed using one or more electrostatography-based engines (12). The layers (22) are transferred for deposition on a part build surface. For each of the layers (22), the part build surface is heated to a temperature within a range between a flowable temperature and a thermal oxidation threshold to form a flowable part build surface, and the developed layer (22) is pressed into contact with the flowable build surface (88) to heat the developed layers (22) to a flowable state and form a new part build surface (88) which is fully consolidated. The new part build surface (88) is then cooled to remove the heat energy added during heating step before repeating the steps for the next developed layer.

    Abstract: Ultrasonic additive manufacturing (UAM) of surface members for a box-like part such as a crash structure or load-bearing structure in a vehicle is disclosed. In one aspect of the disclosure, a method for building a box-like part includes 3-D printing separately, using UAM, the one or more flat surface members in a horizontal plane relative to a print substrate. The method further includes assembling together the surface members at or proximate respective edges thereof to form the box-like part, In some embodiments, protrusions and other features are added to the surface members. In embodiments involving crash structures, trenches are machined into the inner surfaces to enable tailored deformation of the crash structure during an impact event.
