Usage Tips for Optimal Printing:

• Resin Selection: Experiment with different resins to find the one that best suits your needs. Elegoo offers a wide range of options, but third-party resins are also compatible. Consider factors like hardness, flexibility, and color when choosing.
• Slicing Parameters: Properly tuned slicing parameters are crucial. Start with Elegoo’s recommended settings for your chosen resin in CHITUBOX or Lychee Slicer and then fine-tune based on your results. Important settings include:
  • Layer Height: Lower layer heights provide finer detail but increase print time. 0.03mm - 0.05mm is a good starting point.
  • Exposure Time: This determines how long the UV light cures each layer. Overexposure can lead to bloating and loss of detail; underexposure results in weak prints.
  • Bottom Layer Count and Exposure Time: These ensure the initial layers adhere strongly to the build plate. Increase these values if you experience adhesion issues.
  • Lift Speed and Distance: Optimize these to prevent suction forces from separating the print from the FEP film.
• Supports: Use supports judiciously. Generate them automatically in your slicer and then manually edit them to ensure proper support for overhangs and islands. Pay attention to support thickness and density to balance strength and ease of removal.
• Leveling: The Mars 5 Ultra’s leveling process is generally straightforward, but ensure the build plate is perfectly level before starting a print. Re-level periodically, especially after moving the printer or changing resins.
• Resin Handling: Always wear gloves and eye protection when handling resin. Work in a well-ventilated area. Store resin in a cool, dark place when not in use. Filter the resin back into the bottle after each print to remove debris.
• Post-Processing:
  • Washing: Clean your prints thoroughly in isopropyl alcohol (IPA) or a resin cleaner. Two cleaning stages (a pre-wash and a final wash) are recommended.
  • Curing: After washing, cure the prints under UV light to fully harden them. A dedicated curing station provides consistent and even curing.
• FEP Film Care: The FEP film in the resin vat is a consumable. Inspect it regularly for damage and replace it when necessary. Avoid using sharp objects in the vat that could puncture the film.
• Maintenance: Clean the printer regularly, including the LCD screen and build plate. Keep the air filtration system clean to minimize odors.
