Abstract: A trim panel for an aircraft interior includes a first sound attenuating layer, a structural layer and a second sound attenuating layer. The structural layer is coupled to the exterior sound attenuating layer, and has an exterior side and an opposite interior side. The structural layer defines a plurality of passages that open to both the exterior side and the interior side so as to minimize radiation of noise due to a hydrodynamic shortcut created by each of the passages across the structural layer. The second sound attenuating layer is coupled to the structural layer and has a high sound absorption characteristic. The second sound attenuating layer is configured to be disposed adjacent to the aircraft interior.

Abstract: A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8?) selectively at selected positions of the layer. In the process in the second step the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18?) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.
