摘要

In the device for additive manufacturing of components, a carrier platform can be inserted into a pressure tank filled with a photostructurable liquid polymer. At least one, which emits monochromatic electromagnetic radiation, which is suitable for crosslinking the photostructurable polymer, is arranged below the pressure tank, with which the respective component is built up in layers when the carrier platform is moved gradually and the radiation source is influenced accordingly. At least one camera is arranged or movable below the bottom of the pressure tank in such a way that at least the surface area of the carrier platform on which the respective component is built is imaged. The camera (s) are connected to an electronic evaluation unit in which the position and / or orientation of the surface of the carrier platform facing the bottom of the pressure tank and / or at least one body arranged on the surface of the carrier platform facing the bottom of the pressure tank is determined. The electronic evaluation unit is designed in such a way that any deviations detected from a specification in the CAD model are corrected in such a way that the component can be produced with the geometry and dimensions specified for the component.
