1. Product Overview
The SUNLU Standard Plus Resin is an advanced photopolymer resin designed for LCD 3D printers, offering enhanced precision, toughness, and faster curing times compared to standard resins. It is suitable for a wide range of 3D printing applications, from detailed models to functional parts.
2. Safety and Handling
Always prioritize safety when handling photopolymer resins. Follow these guidelines:
- Wear Protective Gear: Always wear gloves and safety glasses to avoid direct skin and eye contact with the resin.
- Ventilation: Use the resin in a well-ventilated area to minimize exposure to fumes.
- Avoid Ingestion: Do not take orally. Keep away from children and pets.
- Skin Contact: In case of skin contact, wash immediately with soap and water.
- Eye Contact: In case of eye contact, flush immediately with plenty of water and seek medical attention.
- Storage: Store the resin in a sealed container, away from direct sunlight and UV light sources, in a cool, dry place between 15-35°C (59-95°F). Avoid dust contamination.
- Disposal: Dispose of cured resin and waste materials according to local regulations. Never pour liquid resin down the drain.
3. Setup and Preparation
- Shake the Bottle: Before each use, shake the resin bottle thoroughly for at least 30 seconds to ensure all components are well mixed.
- Printer Compatibility: This resin is compatible with most 4K/8K/LCD/DLP/SLA 3D printers that use 395-405nm UV light for curing.
- Environment: Ensure your printing environment is clean, well-ventilated, and maintained at an optimal ambient temperature of 25-30°C with relative humidity below 60%.
- Pouring Resin: Carefully pour the desired amount of resin into your printer's resin vat. Avoid overfilling.
4. Operating Instructions (Printing Parameters)
The following parameters are suggested starting points for printing with SUNLU Standard Plus Resin. Optimal settings may vary depending on your specific 3D printer model and environmental conditions. Always perform calibration prints to fine-tune your settings.
| Parameter | Monochrome LCD Screen | RGB LCD Screen | Notes |
|---|---|---|---|
| Print optimum ambient temperature | 25-30°C / <60%RH | Maintain stable environment | |
| Recommended print layer thickness | 0.05mm | Standard layer height | |
| Bottom layer number | 5-10 | Number of initial layers for bed adhesion | |
| Bottom exposure time (s) | 10-60s | 20-80s | Longer time for better adhesion |
| Normal layer exposure time (s) | 2-4s | 4-15s | Adjust based on detail and printer power |
| Lifting height (mm) | 6-10 mm | For 7-inch or larger machines: >8mm; for 10-inch or larger machines: >10mm | |
| Lifting speed (mm/min) | 60-120 | Speed at which the build plate lifts | |
| Return/descent speed (mm/min) | 120-180 | Speed at which the build plate descends | |
| Extinguishing delay time (s) | 0.5-1 | Time delay before next layer exposure | |
For large models, it is recommended to slightly increase the exposure time to ensure proper curing.
5. Post-Processing and Maintenance
- Cleaning: After printing, carefully remove the model from the build plate. Clean the printed model using 95% or higher purity ethanol or isopropanol. Ultrasonic cleaning for 5-6 minutes is recommended. Brushing can enhance the cleaning effect.
- Post-Curing: After cleaning, cure the model in a post-curing chamber for 3-5 minutes. This step enhances the mechanical properties and durability of the print.
- Resin Vat Maintenance: After printing, filter any uncured resin back into the bottle for future use. Clean the resin vat and build plate thoroughly with isopropyl alcohol.
6. Troubleshooting Common Issues
- Print Failure/Poor Adhesion:
- Ensure the build plate is level and clean.
- Increase bottom exposure time.
- Verify ambient temperature is within the recommended range (25-30°C).
- Shake the resin bottle thoroughly before use.
- Soft or Brittle Prints:
- Increase normal layer exposure time.
- Ensure adequate post-curing.
- Check resin shelf life.
- Excessive Odor:
- Ensure proper ventilation in your printing area.
- While SUNLU resin has minimal odor, individual sensitivity varies.
- Resin Leakage:
- Inspect the resin vat for damage or improper installation.
- Ensure the resin bottle cap is securely tightened after use.
If you encounter persistent issues, refer to your 3D printer's manual or contact SUNLU customer support for assistance.
