Screen Protector: Prevents resin from contaminating the screen when the FEP is damaged, extending the LCD screen's lifespan and saving on replacement costs. High Transmittance: Boasting over 95% light transmittance, this screen protector film doesn't affect the 405nm ultraviolet rays needed to cure the resin, maintaining your 3D printer's printing accuracy.

Enjoy consistent print quality after installation – just smooth it out! Easy Installation: Refer to the image for installation steps and use a spatula to avoid air bubbles during application.
