Abstract:
1. A method for manufacturing a three-dimensional object by selective solidification of a build material applied in layers, which comprises the steps of: applying, via an application device, the build material onto one of a substrate or an already solidified layer of the object to be manufactured, the application device including a movably mounted reservoir container for receiving the build material, the reservoir container being, for application of a layer, transferred from a waiting position into an application position and, before solidification of the layer, from the application position back into the waiting position, the reservoir container having a separating element mounted movably, including shiftably, with respect to container walls of the application device and in the application position extends substantially parallel to the layer to be generated, displacement of the separating element causes a part of the reservoir container, the reservoir container being disposed in the application position, first to be opened for an application of the build material and then to be closed again for manufacture of the layer to be solidified, by partial removal of an applied, not yet solidified build material, the reservoir container being completely closed after the separating element has caused the part of the reservoir container to be closed again; lifting of the reservoir container away from the layer to be solidified during a transfer of the reservoir container from the application position into the waiting position; and lowering of the reservoir container during a transfer of the reservoir container from the waiting position into the application position.
