Abstract

The present invention relates to a device as well as a method for creating three-dimensional structures consisting of a material to be consolidated, in particular a material containing organopolysiloxane, by way of locally selective consolidation of the latter as a result of light-induced organic cross-linking. The device is characterized by a movable focusing optical system for the formation of one or a plurality of laser foci, wherein either the laser beam of a laser source can be introduced into the material to be consolidated through the material container and a movable carrier unit is arranged in said container or the focusing optical system is immersed into the material bath and the laser beams can be introduced into the material to be consolidated via a beam exit area of the focusing optical system. In the method, a focusing optical system that is movable in at least one plane is used for the formation of at least one laser focus, and a movable carrier unit is positioned in the material to be consolidated in one embodiment.
