ELEGOO Saturn 3 vs Saturn 4 – Check Which One Is Best & Why?

Why Do I Recommend The ELEGOO Saturn 4? 

• The Elegoo Saturn 4 has automatic bed leveling for faster setup and more consistent first-layer adhesion, while the Elegoo Saturn 3 uses manual screw-based leveling.
• Elegoo Saturn 4 includes intelligent resin shortage detection for preventing failed prints caused by empty resin vats, whereas the Elegoo Saturn 3 lacks resin level monitoring.
• It features residue detection for identifying cured debris in the resin tank before printing begins, while the Elegoo Saturn 3 does not include residue sensing.
• The Elegoo Saturn 4 comes with one-click self-check diagnostics for quickly verifying printer readiness and reducing setup errors, whereas the Elegoo Saturn 3 relies on manual pre-print checks.
• Elegoo Saturn 4 supports a flip-up cover design to simplify access during resin filling and print removal, while the Elegoo Saturn 3 uses a traditional removable cover.
• It has a higher-rated power supply for supporting added sensors and automation features during operation, while the Elegoo Saturn 3 uses a lower-capacity power adapter.
• The Elegoo Saturn 4 includes multiple safety and failure alerts for leveling errors and print interruptions, whereas the Elegoo Saturn 3 does not provide automated failure notifications.
• Elegoo Saturn 4 features an updated control system optimized for automated workflows and monitoring functions, while the Elegoo Saturn 3 uses a more basic controller focused on manual operation.

Maybe the ELEGOO Saturn 3 price can make you comfortable because it’s a little bit cheaper than the ELEGOO Saturn 4. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

What Common Both Can Do?

• Resin Printing Technology: Both printers use MSLA LCD resin printing, which cures entire layers at once using UV light. This allows for high precision and consistent layer exposure across the build plate.
• LCD Resolution: Each model uses a 12K monochrome LCD panel, enabling extremely fine detail reproduction. High-resolution panels are critical for sharp edges and smooth surface finishes.
• XY Resolution: The shared XY pixel size of approximately 19 × 24 microns allows both printers to capture fine textures and small features. This matters especially for miniatures, dental models, and jewelry work.
• LCD Size: Both models use a 10-inch-class LCD, providing a large printable area while maintaining high resolution. This balances productivity with detail accuracy.
• UV Light Source: The COB LED combined with a Fresnel lens ensures even light distribution across the screen. Uniform lighting reduces layer inconsistencies and print defects.
• UV Wavelength: A standard 405 nm UV wavelength is used in both printers, ensuring broad compatibility with most commercial resins. This makes resin selection flexible and straightforward.
• Z-Axis Structure: Dual linear rails are used on both models to stabilize vertical movement. This improves layer alignment and reduces wobble during printing.
• Z-Axis Lead Screw: Precision ball screws are shared across both printers for accurate and smooth Z-axis motion. This contributes to consistent layer height and surface quality.
• Build Plate Material: Each printer uses a CNC-machined aluminum build plate, providing rigidity and even surface contact. A solid build plate helps maintain adhesion throughout long prints.
• Resin Vat Material: Both printers include metal resin vats, which are more durable than plastic alternatives. Metal vats also resist warping and chemical wear over time.
• File Format Support: Support for STL and OBJ files allows users to work with industry-standard 3D model formats. This ensures compatibility with most CAD and modeling software.
• Slicer Compatibility: Both models are designed to work seamlessly with CHITUBOX. Using the same slicer simplifies workflow transitions between the two printers.
• Touchscreen Control: Each printer features a built-in touchscreen for local control. This allows easy navigation of settings, file selection, and print monitoring.
• USB Printing: USB-based file transfer is supported on both models. This provides a reliable and offline method of sending print jobs to the printer.
• Power Input: Both printers accept a wide AC input range of 100–240V. This makes them usable in different regions without special power converters.
• Cooling System: Active internal cooling is present in both models to manage heat from the UV light and electronics. Proper cooling helps maintain consistent performance during long print sessions.
• Application Focus: Both the Saturn 4 and Saturn 3 are designed for high-detail resin printing. They are well-suited for professional and enthusiast use where precision is a priority.
