摘要： A method for removing a support structure of a component produced by additive manufacturing is made possible, in a particularly simple manner, by repeatedly deflecting the free end of the support structure, by impingement of a bending moment, out of an initial position into a deflected position in such a way that the support structure experiences work hardening due to plastic deformation at a defined point, in particular at its fixed end, until the support structure breaks at that point upon a further deflection. A component produced by additive manufacturing and a bending apparatus for removing a support structure are also provided.

摘要： Method for additive manufacturing of at least one component comprises the manufacture, by depositing and selective melting of layers of powder, of at least one intermediate assembly comprising the component produced at an inclined angle and forming an angle of between 20° and 70° with a manufacturing support plate, a support interposed between the support plate and a lower base of the component, and at least one local supporting element resting against the rear frontal face of the component. During the selective-melting phases of the manufacturing step, incipient cracks are formed in regions of connection of the support and of the supporting element to the component. The component is separated from the support and the local supporting element after the manufacturing step by breaking of the connecting regions.

摘要： A 3D printer includes a build plate providing a surface on which an object is printed. Prior to printing, a sheet is fixed to the surface of the build plate. The sheet is composed of a material that adheres to a binder component of the feedstock used to print the object. During printing, the first layer of the printed object forms a bond with the sheet, which secures the location of the first layer and resists movement of the object during printing. Following printing and the object gaining sufficient rigidity, the object and sheet can be removed together from the printer. The sheet may then be peeled from the object, and the object can undergo debinding and/or sintering to create a finished object.

摘要： The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.
