IV. Printing with the Elegoo Saturn S

Printing with the Elegoo Saturn S

3D printing has revolutionized prototyping and manufacturing, and the Elegoo Saturn S is at the forefront of this innovation. To fully harness the potential of this printer, understanding the entire process from preparation to post-processing is essential. Here’s a detailed guide:

Preparation and Calibration

  • Clean Build Plate: Start by ensuring the build plate is clean. Any residue or particles can affect print quality.
  • Leveling: Level the build plate accurately. An unlevel plate can lead to adhesion problems and uneven prints.
  • Calibration Guide: Follow the specific instructions provided by Elegoo to calibrate the build plate. This step is crucial for accurate and successful prints.

Resin Printing Process

  • Adding Resin: Pour the desired resin into the resin vat. It’s important to maintain the resin at the recommended level for consistent results.
  • LCD Curing Technology: The Elegoo Saturn S employs LCD curing technology. Here, a UV LED light source selectively cures each layer of resin.
  • Layer-by-Layer Printing: The build plate lifts gradually after each layer is cured, forming the 3D print layer by layer.

Post-Processing Techniques

  • Removal: Once printing is complete, carefully remove the object from the build plate.
  • Cleaning: Clean the print with isopropyl alcohol to eliminate excess resin.
  • Finishing Touches: Depending on your preference, you can sand, polish, or paint the print to achieve the desired finish.

Wash and Cure Process for Resin 3D Prints

This process is critical for ensuring the durability and quality of your 3D prints.


  • Purpose: The primary goal is to remove any uncured resin from the print’s surface.
  • Method: Use a wash and cure station, or alternatively, immerse the print in isopropyl alcohol (IPA), gently agitating until all uncured resin is dissolved.
  • Importance: This step prevents the print from remaining tacky and prepares it for curing.


  • Objective: Finalize the polymerization of the resin and harden the print.
  • Process: Expose the cleaned print to UV light in a curing station or UV chamber.
  • Curing Time: Follow the recommended curing times based on the resin type.
  • Benefits: Curing enhances the print’s mechanical properties, making it strong and durable.

Review of the ELEGOO Mercury X Bundle

The ELEGOO Mercury X Bundle, designed for post-processing large resin 3D printed models, is an excellent addition to any 3D printing setup. It’s particularly compatible with Elegoo Saturn and Mars MSLA 3D printers. The bundle includes a separate wash station and cure station, both crucial for the post-printing process.


  • Large Capacity: The 7.5-liter wash station can handle large prints, making it ideal for models printed on Elegoo Saturn and Mars 3 printers.
  • Efficient Washing and Curing: The bundle allows you to wash and cure prints simultaneously, significantly improving throughput.
  • Enhanced Print Quality: With its 28 LED lights and Fresnel lens, the curing station emits optimal 405nm UV light, improving the quality and durability of prints.
  • User-Friendly Interface: The single knob design for operation is intuitive. The LED display adds to the convenience, showing the remaining time for processes.
  • Safety: A UV cover blocks over 99.9% of ultraviolet rays, ensuring user safety during the curing process.


  • Ease of Use: The top-loading design and simple controls make the process straightforward, even for beginners.
  • Size Advantage: Its capacity to handle larger prints is a significant advantage, especially for those working on big projects.
  • Quality Improvement: The curing station’s light configuration ensures thorough and even curing, which is vital for the final print’s strength and appearance.


  • Limited Compatibility: While perfect for Elegoo printers, users with other brands may need to check compatibility.
  • Special Considerations for Water-Washable Resins: The manufacturer advises using running water for washing models printed with water-washable resin instead of the washing station.


  • Drying Before Curing: It’s recommended to dry the model after washing and before curing for the best results.
  • Pre-fill Liquid in Washing Station: Ensure the washing station is pre-filled with the solvent to prevent issues with the stirring wheel.

Safety Note: Always handle uncured resin and post-processed parts with gloves, and work in a well-ventilated area. Dispose of used cleaning solutions responsibly.

V. Common Problems and Troubleshooting

The Elegoo Saturn S is a robust and advanced 3D printer, but like any technology, it can encounter issues.

The Elegoo Saturn S is a robust and advanced 3D printer, but like any technology, it can encounter issues. Understanding these common problems and knowing how to troubleshoot them will ensure a smoother 3D printing experience. Let’s explore some of these issues:

Failed Adhesion

  • Problem: Prints not sticking to the build plate.
  • Solutions:
    • Leveling the Build Plate: Re-level the build plate. An uneven plate can cause adhesion problems.
    • Cleaning the Plate: Make sure the build plate is clean. Residue or dust can prevent proper adhesion.
    • Adhesive Application: Use a thin layer of an adhesive, like a glue stick, to enhance adhesion.
    • Resin Viscosity: Check if the resin is too thick or cold, affecting its ability to adhere properly.

Layer Shifting or Artifacts

  • Problem: Misalignment or anomalies in the print layers.
  • Solutions:
    • Tightening Screws: Check all screws, especially those on the Z-axis, and tighten them if loose.
    • Z-Axis Calibration: Ensure the Z-axis is properly aligned. Misalignment can cause layer shifts.
    • Software Settings: Review your slicing software settings. Incorrect parameters can lead to artifacts.
    • Resin Curing: Ensure the resin is curing properly. Inadequate curing can lead to shifts and artifacts.

Excessive Resin Consumption

  • Problem: Higher than expected usage of resin.
  • Solutions:
    • Layer Height Adjustment: Reducing the layer height can help save resin, but it might increase print time.
    • Optimizing Exposure Time: Adjust the exposure time. Overexposure can lead to excess resin use without improving print quality.
    • Hollowing Models: If applicable, hollow out the models in the slicing software to reduce the amount of resin used.
    • Efficient Model Placement: Arrange models on the build plate to maximize space and minimize supports, reducing resin use.

Additional Tips

  • Regular Firmware Updates: Keep your printer’s firmware up to date. Sometimes, issues are resolved through software updates.
  • Resin Storage and Handling: Store resins properly, as environmental factors can affect their performance.
  • Ambient Temperature: Maintain an optimal room temperature for printing. Extreme temperatures can affect print quality and resin behavior.
