Device with hatch for additive manufacturing

Abstract

A device for additive manufacturing, in particular powder-bed-based additive manufacturing, having a build-chamber wall, which defines a build chamber and is designed to separate the build chamber from an outside area. The build-chamber wall has a hatch, which is designed for transferring at least partially a component that is to be built up in layers from the build chamber through the hatch into an outside area during an additive manufacturing process, and the component can be built up along at least one transferring direction beyond a dimension of the build chamber. A corresponding method includes the provision of a first portion of the component to be manufactured in layers in the build chamber, and the building up in layers of a second portion, adjoining the first portion, wherein an already built-up sub-portion of the component is transferred in layers from the build chamber through the hatch into the outside area.
