Apparatus and Method for generative manufacture of at least one component region of a component

The invention relates to a device (10) for generative manufacture of at least one component region of a component (12), particularly a component (12) of a turbomachine. The device (10) can in this case at least one coater (14) for applying at least one powder layer of a component material to at least one assembly and joint zone comprise at least one lowerable component platform (16), the coater (14) relative to the component platform (16) is movable. In addition, the device (10) comprises at least one suction device (36) for suction of the process gases and / or particles. Here, the coater (14) comprises at least one suction channel (22) or at least one suction tube with at least one in direction of the component platform (16) aligned suction opening (24), wherein the suction channel (22) or the suction pipe are arranged such that pre-defined at a standstill position of the coater (14) outside the component platform (16) of the suction channel (22) or the suction pipe with the suction device (36) for deflecting a gas and / or particle stream is in operative connection. The invention further relates to a method for generative manufacture of at least one component region of a component (12) and a coater (14).
