This invention relates to a distributed balanced scanning system and method for additive manufacturing, belonging to the field of additive manufacturing technology. The method includes: acquiring data information of the part to be processed, including data information of multiple slice layers; processing the data information to obtain initial graphic partition data; adjusting the initial graphic partition data, provided that the initial graphic partition data meets adjustment conditions, to obtain first target graphic partition data; re-estimating the total scanning time of each laser based on the first target graphic partition data, until the time difference between the total scanning times of the lasers is less than a time threshold or the number of iterations reaches a preset number, and obtaining second target graphic partition data; and allocating the second target graphic partition data to each laser for scanning and printing. This method achieves precise balancing of scanning time among multiple lasers, avoiding waiting and efficiency losses caused by uneven load, and significantly improving parallel processing efficiency.
