Application: Method for additive manufacturing of a three-dimensional object (Patent ID: US20240059021A1)
The patent filed by Bayerische Motoren Werke AG describes a method for additive manufacturing of a three-dimensional object using a construction material that includes at least one UV-curable component. The process involves exposing the material to UV radiation to form a green body, which is then subjected to thermal energy for curing. The exposure to UV radiation is controlled to prevent the curing temperature of the components from being significantly exceeded, ensuring the formation of the three-dimensional object without compromising its integrity.
The method includes various steps to control the exposure process, such as utilizing a detection device in the construction chamber to monitor parameter data and temperature values, adjusting process parameters like UV entry timing, intensity, exposure time, and wavelength, and evaluating data from previous manufacturing methods or simulations. Additionally, artificial intelligence technologies are employed to analyze and process the data for influencing the exposure control. The construction material consists of components that cure either by UV radiation or thermal energy, with structural members being constructed during the process to provide support and facilitate the manufacturing of complex geometries. The resulting three-dimensional object, such as a vehicle component, is manufactured with precision and structural integrity, demonstrating the innovative approach to additive manufacturing outlined in the patent.
