摘要：The present invention relates to a generative method of fabrication and anaccompanying device with which components can be fabricated from a combination ofmaterials. The device comprises a bottom surface (1) with a lowerable building platform(2), a leveling mechanism (5) for leveling a first material (4) in a processing plane (3) abovethe building platform (2), a laser beam source for emitting a laser beam (11), a processingunit (6) with a focusing optical system (8) for focusing the laser beam (11) onto theprocessing plane (3) and a positioning mechanism which can position the processing unit(6) in any desired positions in a plane parallel to the processing plane (3) above thecomponent (14). Furthermore, the device is provided with a suction device (10) forsectioning off the material from the processing plane (3) and an introduction mechanism(9) for a second material (12) with which the latter is brought into the focal range of thelaser beam (11). This device permits fabrication of components of any desired complexityand adapted to a certain function, in which individual regions can be made of a second,harder material to increase sturdiness or to improve wear-resistance.
