Embodiment Construction

[0031] figure 1 A manufacturing setup is shown in which the concepts of the present disclosure may be implemented. figure 1 The device 10 has a table 11 with an upper surface 11a. Here, the upper surface 11a is flat. Provided in the surface 11a of the mesa 11 is a concave well 12, the sides of which are defined by side walls 11b extending in a vertical direction from the surface 11a of the mesa. Arranged in the concave well 12 and having an extension in the plane of the surface of the stage (XY plane) matching the extension of the concave well is a support plate 13 . The support plate 13 also has a flat upper surface 13a and is movably arranged in the concave well 12 so that the depth of the concave well in the direction (Z direction) perpendicular to the surface 11a of the stage 11 is such that the surface 11a of the stage 11 and the support The depth of the wells between the surfaces 13a of the plates 13 is variable. For example, the support plate 13 may be moved by a ...

Abstract

A method is provided of sintering a green object body to form a manufactured object. The method comprises providing a green object body. The green object body comprises granular construction material bound together by a binder. The method comprises providing a green support body for supporting the green object body. The green support body comprises granular construction material bound together by a binder. The method comprises supporting the green object body with the green support body. The method comprises sintering the green support body together with the green object body supported by the green support body. A method of manufacturing an object, a method of processing object data, a data carrier carrying program instructions and an object data processor are also provided.

Description

technical field [0001] The present disclosure relates to sintering methods, and more particularly to sintering methods for sintering green objects to form desired objects. In particular, the present disclosure applies to the sintering of green objects produced by additive manufacturing methods in which particulate material, such as metal powder, is deposited into the build area in multiple layers, each layer The parts are joined together during or after the deposition of each layer to form parts of the object whereby the object is formed in the build area from a series of layers. The bonded portions of each layer of the object are generally also bonded to the bonded portions of the previous layers, so that the object is formed in a continuous fashion through successfully deposited layers. Binding is usually by selective deposition of the binding agent. The present disclosure also relates to a method of manufacturing an object including a sintering method, a method for proces...
