This lcd screen protector is a genuine replacement product for the lcd screen of the Uniformation GK3 Ultra 16K 3D printer. The screen protector is made of anti-static PET, which means that there will be no static electricity or air bubbles when you remove it. Up to 95% of the light is transmitted for high precision printing. The screen protector is 0.2mm and 13.8 x 8.3 inches, which is slightly larger than the screen to prevent resin from leaking onto the screen. The package contains 5 pieces.
