1. A method for improving a lifespan of a liquid crystal display (LCD) of a masked stereolithography (MSLA) 3D printer, the method comprising the steps of:
slicing a three-dimensional (3D) image into two-dimensional (2D) images;
outputting the 2D images to the LCD;
calculating irradiation area coordinates of UV LEDs in accordance with the 2D images;
irradiating UV light of the UV LEDs on an area matching with the 2D images in accordance with the calculated irradiation area coordinates of the UV LEDs; and
collecting and storing accumulation irradiation time data of the UV LEDs to calculate average irradiation time per area.
