How to choose the right one
-
Match tank dimensions
You must verify the resin tank size fits your printer model exactly. The Saturn 3 Ultra Aluminum Resin Tank measures 14.4 inches in length and 8.15 inches in width. This specific footprint ensures the tank sits correctly on the printer bed. If you own a Mars 4 Ultra, the metal tank is 10 inches long. Using an incorrect size causes alignment issues. Always check the printed dimensions of your current tank before buying a replacement part to ensure proper fit.
-
Select release film type
Your LCD screen needs protection from UV light and resin. The Mars 4 Ultra ACF Release Film 5-Pack offers high transmittance for consistent curing. These films are 8.86 inches long and 6.3 inches wide. ACF films are designed for specific screen resolutions. Replacing them regularly maintains print quality. If your screen shows uneven curing, check the film condition. The clear color allows you to see the screen status. Keep a spare pack ready for routine maintenance.
-
Check build plate size
The build plate surface area determines your maximum print size. The Saturn 3 Aluminum Build Plate is 11.8 inches long and 7.48 inches wide. This larger area allows for bigger models. The Mars 4 Ultra Aluminum Build Plate is smaller at 8.26 inches long. Choose the plate that matches your printer’s X and Y axes. A flat, stable surface ensures first-layer adhesion. Verify the width and length match your printer’s specifications before ordering.
-
Prioritize material durability
Resin is corrosive and can damage plastic parts over time. The Saturn 3 Ultra Aluminum Resin Tank uses a robust aluminum build for durability. Aluminum resists chemical degradation better than standard plastics. The Mars 4 Ultra also offers a metal tank option. Metal construction provides a stable, vibration-free printing experience. If you print frequently, choose metal parts. They last longer and maintain their shape. Check if the part is made of aluminum or plastic.
-
Verify pre-installed films
Some tanks come with the release film already attached. The Saturn 3 Ultra Aluminum Resin Tank includes a pre-installed film. This saves you time during setup. The Mars 4 Ultra Metal Resin Tank also has a pre-installed ACF film. Buying a tank without a film requires you to install it carefully. Pre-installed films reduce the risk of misalignment. Check the product description to see if the film is included. This detail affects your initial setup time.
