Abstract: An apparatus and to a method for producing a three-dimensional object built up from at least one material layer by selective solidification of at least one powder raw material applied successively in raw material tracks to a build platform via an application unit of the apparatus. In this case, the apparatus for solidifying the raw material via energy input from a beam has an irradiation unit forming a build group together with the application unit, wherein the irradiation unit having a contiguous group of irradiation elements is rotatably mounted on the application unit.

Abstract: A deformable structure for occupant protection in vehicles has hollow energy-absorbing elements which are disposed between walls or other components. The hollow bodies are tube portions which are predeformed perpendicularly to their longitudinal axes and which are disposed with the tube axes parallel to the walls individually in a predeterminable arrangement or joined together in single-layer or multilayer fashion, and wherein the degree of predeformation is between 0.1% and 85% of the open width of the undeformed tube in the direction of the deformation impact force.
