Abstract
An apparatus for the additive manufacturing of three-dimensional structures from a material that is to be solidified by way of location-selective solidification thereof as a result of light-induced chemical and/or physical processes in the material includes a laser source for producing a laser beam, a focusing optical unit for focusing the laser beam so as to form a laser focus, and a beam-splitter optical unit for splitting the laser beam into at least two partial laser beams. The laser source, the focusing optical unit and the beam-splitter optical unit are arranged such that the laser beam, starting from the laser source, passes first through the focusing optical unit and then through the beam-splitter optical unit and the partial laser beams finally are each directed to different locations on the material that is to be solidified.
