Abstract: The present invention relates to an apparatus for a manufacturing system for additive manufacturing of articles, in particular for a manufacturing system for selective laser melting. The apparatus comprises a process chamber (1) for providing at least one working space in an area of a build field, and at least one partition wall (2) which divides the process chamber (1) into at least two sub-chambers (1a, b), at least one of the at least two sub-chambers (1a, b) providing the at least one working space. This sub-chamber has at least one powder coater (22, 22a, b) for applying the powdery material (7) to the build field, and at least one optical module (9a, b). At least one gas inlet (4a, b) or at least one gas outlet (24a, b) are arranged in the at least one partition wall (2).

Abstract: An additive manufacturing system for manufacturing a component, the additive manufacturing system comprising a frame, an additive manufacturing machine disposed on the frame, a processor disposed on the frame and electrically coupled to the additive manufacturing system, a memory unit electrically coupled to the processor and containing instructions to control the additive manufacturing system.

Abstract: A dynamic gas flow system used in additive manufacturing systems, the dynamic gas flow system comprising at least one gas inlet, at least one gas outlet, at least one bypass gas inlet, a dynamic flow surface, and a gas flow management system to provide feedback on conditions in the build chamber to adjust operation of the dynamic gas flow system.

Abstract: A heating device for heating a powder during the production of a 3D shaped part. The heating device has an infrared (IR) lamp and a housing in which a construction chamber is provided. The construction chamber is bounded at the bottom by a construction platform for receiving the shaped part and is supported on a support plate. The IR lamp heats the powder during production of the 3D shaped part in the construction chamber. For ensuring an optimized heat transfer to the sintering or melting powder with a particularly homogeneous temperature distribution, a partition wall composed of an IR radiation transparent material is arranged between the construction chamber and the IR lamp.
