The invention relates to a method for producing a three-dimensional object by means of a powder-based additive production method from at least one first powdery material, wherein the at least one first powdery material comprises at least one first compound having a first reactive group a). The first reactive group a) is selected from the group consisting of an isocyanate group, a blocked isocyanate group, or a mixture thereof. The invention further relates to a component produced using the method according to the invention, and to powdery material that is suited for the method according to the invention.

Method for producing products by means of additive manufacturing methods using reactive powders, and products thereof

A lighting device for vehicles, in particular a signal light, with a light source for emitting a light beam and an optical unit associated with the light source for producing a predetermined light function, the optical unit having a holographic element and a lens arranged in the main emission direction in front of the holographic element, the holographic element comprising such a diffraction structure that the light beam emitted from the light source onto the holographic element is varied according to a predetermined illumination pattern such that the holographic light beam lights an illumination surface of the lens to generate the light function.
