DEVICE FOR ADDITIVE PRODUCTION OF COMPONENTS IN WHICH A PLATFORM CAN BE INSERTED INTO A PRINTING TANK FILLED WITH A PHOTOSTRUCTURABLE LIQUID POLYMER

摘要

In the device for the additive manufacturing of components, a carrier platform can be introduced into a pressure tank filled with a photo-structurable liquid polymer. Below the pressure tank is at least one that emits monochromatic electromagnetic radiation that is suitable for crosslinking the photo-structurable polymer, with which the respective component is built up in layers with a step-by-step movement of the carrier platform and corresponding influencing of the radiation source. At least one camera is arranged or movable below the bottom of the pressure tank in such a way that an image of at least the surface area of the carrier platform on which the respective component is built takes place. 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 detected deviations from a specification in the CAD model are corrected in such a way that the component can be manufactured with the geometry and dimensions specified for the component.
