1. A photopolymerization 3D printing system comprising:
a processing device configured to determine one or more printing layers of an object;
a micro light emitting diode (microLED) array configured to generate light for each of the one or more printing layers, wherein to generate the light for each of the one or more printing layers, the processing device is configured to:
dynamically determine one or more microLED regions in the microLED array, each of the one or more microLED regions including one or more individually addressable microLED emitters,
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, wherein position of at least one of the one or more individually addressable microLED emitter is adjustable; and
a printing component configured to print the one or more printing layers.
