Abstract: The invention relates to a method for monitoring the condition of rotor blades for wind turbines. It is therefore the object of the invention to increase the accuracy of the monitoring of the condition of rotor blades of wind turbines and to allow a localization of faults or defects and their exact description. In the method in accordance with the invention, eigenvibrations of a rotor blade occurring globally at the rotor blade and locally guided elastic waves are permanently detected with time and spatial resolution using a sensor network and actuator network attached to the rotor blade or using a network arrangement of ultrasound transducers. In addition, elastic waves which are guided periodically at predefinable time intervals and which are respectively emitted by an actuator or ultrasound transducer and detected by sensors or ultrasound transducers are in so doing inspected for variations of the emitted waves.

Abstract: An additive layer manufacturing method is disclosed for producing a three-dimensional object and to a corresponding object. Layers of a powder material are applied to a carrier and irradiated, before the following layer is applied, with a laser beam or particle beam selectively only in the areas of the layer which correspond to the three-dimensional object to be produced. Irradiation occurs such that the powder material in the corresponding areas is locally melted or sintered. A first portion is constructed before a second portion or the first portion is provided as a separate component, on which a support structure and second portion are constructed. The support structure is constructed in the form of a plurality of support legs, which extend from the first portion to the second portion and are connected thereto at their opposite ends and are spaced apart from one another at least along part of their length.
