Frequently asked questions
What size FEP film fits the ELEGOO Mars 4 and 5?
You need a 206 by 146 mm film for these printers. The ELEGOO 3-Pack and 5-Pack options are cut to this exact dimension. This size ensures the film covers the build plate without overhang or gaps. Using the correct dimensions is critical for maintaining proper resin containment during the printing process.
Is a 0.15mm thickness necessary for Mars 4 prints?
Yes, the official ELEGOO replacements for the Mars 4 and 5 are specified at 0.15 mm. This thickness balances durability with optical clarity. It helps maintain the 95% UV transmittance required for accurate layer curing. Thicker films may reduce light transmission, while thinner ones might tear more easily during removal.
Can I use FEP film from other brands on my Mars 4?
You can use third-party films if the dimensions match your printer. For example, the KOYOFEI 6-Pack measures 200 by 140 mm. While close, this size differs from the official 206 by 146 mm requirement. You must verify that the film fits your specific vat size to avoid resin leaks or curing issues.
What is the difference between FEP and PFA films?
FEP and PFA are both fluoropolymer release films used in resin printing. The products listed here are all FEP type. FEP is generally more affordable and easier to install. PFA offers higher heat resistance and durability but is often more expensive. Your printer manual will specify which material is recommended for optimal performance.
How often should I replace the FEP film on my printer?
You should replace the film when you notice scratches, tears, or reduced transparency. The ELEGOO 5-Pack provides extra sheets for regular maintenance. The KOYOFEI 6-Pack offers even more replacements for frequent users. Regular changes prevent resin from sticking to the tank bottom, which can ruin your prints and damage the screen.
Are there metal tank options for the ELEGOO Mars 4?
Yes, there is a metal resin tank available for the Mars 4. This option includes a pre-installed FEP film and is made of aluminum. It measures 10 by 6.93 inches and is 2.8 inches high. This upgrade provides better durability than standard plastic tanks and simplifies film replacement for long-term use.
Does the ELEGOO Saturn 2 tank work with the Mars 4?
No, the Saturn 2 metal tank is not compatible with the Mars 4. The Saturn 2 tank measures 11.5 by 6.79 inches and is designed for larger printers. The Mars 4 vat is significantly smaller. Using the wrong tank will prevent proper assembly and resin containment. Always match the tank to your specific printer model.
