This LCD screen protector is an original replacement part for the GKtwo resin 3D printer from Uniformation. This protection allows 95% of light to pass through, ensuring very precise printing results. The protective film is made of an advanced anti-static PET, so no static electricity or air bubbles will form when you remove this film. The screen protector has perfect adhesion and is designed to be larger than the screen. This prevents resin from leaking onto the screen when the FEP film breaks. This product is 257 x 165 mm and 0.2 mm thick. The package contains 5 pieces.
