2. Safety Precautions
Handling photopolymer resin requires adherence to specific safety guidelines to prevent adverse reactions and ensure a safe working environment.
- Wear Protective Gear: Always wear gloves (nitrile recommended) and a mask (respirator with organic vapor cartridges) to avoid direct skin contact and inhalation of fumes.
- Ventilation: Use the resin in a well-ventilated area to minimize exposure to odors and fumes.
- Temperature Control: Maintain a recommended ambient temperature of 20°C - 25°C (68°F - 77°F) for optimal resin performance and safety.
- Avoid Direct Sunlight: Store resin away from direct sunlight and UV light sources, as this can cause premature curing.
- Emergency Contact: In case of skin contact, wash immediately and thoroughly with plenty of soap and water. If irritation persists, seek medical attention. For eye contact, flush with water for at least 15 minutes and seek immediate medical attention.
- Keep Away from Children: Store resin out of reach of children and pets.

4. Setup and Preparation
- Shake the Bottle: Before each use, thoroughly shake the resin bottle for at least 30 seconds to ensure all components are well mixed. This is crucial for consistent print quality.
- Environmental Conditions: Ensure your printing environment is within the recommended temperature range of 20°C - 25°C (68°F - 77°F). Extreme temperatures can affect resin viscosity and curing properties.
- Pouring Resin: Carefully pour the desired amount of resin into your printer's resin vat. Avoid overfilling.

5. Operating Instructions (Printing Guidelines)
The following settings are recommended starting points for the ELEGOO Mars printer. Optimal settings may vary depending on your specific printer model, ambient temperature, and desired print quality. Always perform calibration prints to fine-tune your settings.
- Bottom Exposure Time: 70 seconds
- Normal Exposure Time: 13-15 seconds
For other printer models, consult your printer's manufacturer guidelines or community-shared settings for 405nm standard photopolymer resins.

6. Post-Processing and Curing
- Remove Print: Carefully remove the printed model from the build plate using a scraper.
- Wash: Clean the printed model thoroughly with 95% (or higher) isopropyl alcohol (IPA) or a specialized resin cleaner. Use a soft brush if necessary to remove uncured resin from crevices.
- Dry: Allow the model to air dry completely or use compressed air. Ensure no residual alcohol remains.
- Post-Cure: Place the dried model under a 405nm UV light source for final curing. Curing times vary depending on the size and complexity of the model, typically ranging from a few minutes to an hour. Ensure all surfaces are exposed to UV light.

7. Maintenance and Storage
- Resin Storage: Store unused resin in its original opaque bottle, tightly sealed, in a cool, dry, and dark place. Avoid exposure to direct sunlight or any UV light source.
- Temperature: Maintain storage temperature between 15°C - 35°C (59°F - 95°F).
- Disposal: Do not pour liquid resin down the drain. Cure any leftover liquid resin under UV light until solid, then dispose of it as solid plastic waste according to local regulations.
- Cleaning the Vat: After printing, filter any remaining resin in the vat back into the bottle using a fine mesh filter to remove cured particles. Clean the resin vat with IPA if changing resin types or for long-term storage.

8. Troubleshooting
If you encounter issues during printing, consider the following common troubleshooting steps:
- Failed Prints/Poor Adhesion:
- Ensure the build plate is properly leveled and clean.
- Increase bottom exposure time.
- Verify the ambient temperature is within the recommended range.
- Check for FEP film damage or cloudiness in the resin vat.
- Soft/Under-cured Prints:
- Increase normal exposure time.
- Ensure the UV light source is functioning correctly.
- Confirm proper post-curing procedures.
- Brittle Prints:
- Reduce normal exposure time slightly.
- Avoid over-curing during post-processing.
- Resin Not Mixing Properly:
- Shake the resin bottle thoroughly before use.
- Ensure resin is stored at the correct temperature.
