Abstract: The invention relates to a method for the generative production of at least one component, a device for performing the method and a motor vehicle, in particular a passenger car. In a method for the generative production of at least one component, a powder of a material is irradiated by means of laser radiation so that it is heated and at least partially melted and the molten material solidifies in order to at least partially form the component. Information relating to the temperature of the material irradiated and/or to be irradiated, in particular thermal radiation, is detected and used for influencing the laser intensity. The laser radiation is conducted at least in sections by means of a light guide to the material and the information relating to the temperature is transmitted in the inner region of the light guide for the purpose of its detection.
