DEVICE AND METHOD FOR PRODUCING THREE-DIMENSIONAL STRUCTURES

摘要

The invention relates to a device and method for producing three-dimensional structures from a material (6) to be solidified, in particular from a material comprising organopolysiloxane, by location-selective solidification thereof as a result of light-induced organic crosslinking. The device comprises a displaceable focusing lens (3, 3a, 3b) for forming one or a plurality of laser foci (5, 5a, 5b), it being possible either for the laser radiation (4) of a laser source (1) to be introduced through the material container (10) into the material (6) to be solidified and a displaceable carrier unit (12) to be disposed in said container (10), or for the focusing lens (3, 3a, 3b) to be immersed in the material (6) to be solidified and the laser beams (11) to be introduced via a radiation emission surface of the focusing lens (3, 3a, 3b) into the material (6) to be solidified. In the method, a focusing lens (3, 3a, 3b) displaceable in at least one plane is used for forming the at least one laser focus (5), and in one embodiment a displaceable carrier unit (12) is positioned in the material (6) to be solidified.
