ACF Film Release 5Pcs 7 Inch 235x160mm For Mars 4 Ultra

Discover the ACF Film Release 5Pcs 7 Inch 235x160mm for Mars 4 Ultra — a high-speed, durable release film crafted for modern UV resin printers. This 0.3mm-thick ACF film is an upgraded alternative to NFEP, engineered to reduce viscosity issues and perform reliably at faster print speeds across Mars 4 Ultra, Mars 5 Ultra, and a broad range of Elegoo and Phrozen printers. With an impressive 95% light transmission, the film delivers clear, sharp layer exposure while boasting excellent flexibility and ductility. Its rugged construction supports daily use, resisting wear and heat (up to 260°C without melting, up to 304°C with newer materials), ensuring long-term print success and fewer failed experiments.

Designed to maximize compatibility, this batch suits Mars 2/3/4/5 series and Phrozen models like Sonic Mini 8K S, Sonic Mini 8K, Sonic 4K 2022, Shuffle series, and more. The ACF film helps prevent resin from sticking to the LCD, delivering a smoother release and cleaner model surfaces for faster post-processing. Important handling notes help you get the best results: pay attention to the front and back sides — the smooth side should contact the resin, while the rough surface faces the UV light source. If the protector is angled, the release film can crack. Because ACF film is elastic and curly, we recommend using tape to fix it to the table for easy tearing and tidy setup.

Benefits & Tips

• Use with Mars 4 Ultra and other supported Elegoo/Phrozen printers to achieve fast, clean releases thanks to high light transmission and improved durability.
• Keep the smooth side facing the resin and the rough surface toward the UV light to ensure consistent curing and easy release.
• Secure the film with a small amount of tape during setup to prevent curling or tearing between prints.
