| description | The burgeoning advancements in Light Emitting Diode (LED) technology have opened avenues for applications beyond traditional display and lighting, notably in the realm of 3D printing. This study introduces a Local Dimming (LD) method that employs LED backlight technology to enhance the edge quality of Liquid Crystal Display (LCD) photocuring 3D printing (LPP). LPP, known for its rapid and cost-effective fabrication, faces challenges with light leakage and precision under high-power ultraviolet (UV) light. By locally adjusting the backlight array's brightness to conform to the digital mask's shape, this study effectively suppresses LCD light leakage and improves edge definition. A comprehensive investigation into the LD method's process parameters—exposure time, pixel compensation coefficient, and initial backlight calculation—reveals significant improvements in print quality. The LD method achieves up to an 81.56% enhancement in dimensional accuracy compared to the conventional full-backlight technique. This research not only addresses the intrinsic light leakage in LCDs but also facilitates the high-resolution printing of complex structures, thus expanding the utility of LED devices in additive manufacturing. |
