Zusammenfassung:	The present invention relates to a method for improving the lifespan of an LCD of an MSLA 3D printer by controlling and partially irradiating UV LEDs only to a portion matching a masking image of the LCD. The method according to the present invention comprises the steps of: slicing a 3D image to generate a 2D masking image; outputting the generated image to an LCD; calculating an LED irradiation area coordinate according to the generated image; and irradiating UV LED only to a portion matching the masking image. 본 발명은 LCD의 MASKING 이미지와 매칭되는 부분에만 UV LED를 컨트롤하여 부분적으로만 조사함으로써 LCD의 수명을 향상시키기 위한 MSLA 3D 프린터의 LCD 수명을 향상시키는 방법에 관한 것으로서, 3D 이미지를 슬라이싱 하여 2D 마스킹 이미지를 생성하는 단계, 상기 생성된 이미지를 LCD로 출력하는 단계, 상기 생성된 이미지에 따른 LED 조사면적 좌표를 계산하는 단계 및 상기 마스킹 이미지와 매칭되는 부분만 UV LED를 조사하는 단계를 포함할 수 있다.
