Zusammenfassung:	A method and system for photopolymerization 3D printing is provided. The system includes a processing device, a micro light emitting diode (microLED) array including one or more individually addressable microLED emitters, and a printing component. The processing device is configured to determine one or more printing layers of an object. The microLED array is configured to generate light for each of the one or more printing layers. The printing component is configured to print the one or more printing layers. To generate the light for each of the one or more printing layers, the processing device is further configured to dynamically determine one or more microLED regions in the microLED array, determine one or more region printing parameters for each of the one or more microLED regions; and determine one or more control signals for the one or more individually addressable microLED emitters included in each of the one or more microLED regions based on the one or more region printing parameters.
