RESIONE TH-BJD Tough Resin for 3D Printers Instruction Manual

1. Introduction

The RESIONE TH-BJD Tough Resin is specifically engineered for 3D printing Ball-Jointed Dolls (BJD) and other articulated models. This 405nm UV-curing resin is compatible with LCD, DLP, and MSLA 3D printers. It offers exceptional wear resistance, scratch resistance, and maintains precise shapes, ensuring joints fit snugly without powdering from friction. The resin is formulated to be non-yellowing over time, preserving the original color of your prints. Its robust properties make models resistant to cracking, impact, and drops, even delicate parts during transportation.

2. Safety Information

Always prioritize safety when handling 3D printing resin. Follow these guidelines:

• Environmental Conditions: Use the resin in an environment with a temperature between 25-35°C (77-95°F).
• Ventilation: Ensure adequate ventilation in your workspace. Avoid using resin in environments with strong ultraviolet light, such as near windows.
• Personal Protective Equipment (PPE): Always wear goggles, nitrile gloves, and a mask when handling resin to prevent skin and eye contact and inhalation of fumes.
• Accidental Contact:
  • If resin splashes into your eyes, immediately rinse with plenty of clean water and seek medical attention.
  • If resin spills on your skin, wash thoroughly with soap and water.
• Resin Storage:
  • Store resin in a cool, dark place, away from direct sunlight.
  • Keep out of reach of children and pets.
  • If the resin will not be used for several days, seal it in an opaque container to prevent contamination.
  • Do not mix used resin with unused resin to avoid contamination.
• Waste Disposal: Do not pour liquid resin directly into drains. Pour waste resin into a transparent container, add a small amount of water, and cure it under sunlight. Once solidified, filter and dispose of it as solid waste according to local regulations.

3. Setup

Proper setup is crucial for successful 3D printing with RESIONE TH-BJD Tough Resin.

1. Resin Preparation: Before use, heat the resin to 70°C (158°F) and shake thoroughly to ensure proper mixing of components.
2. Printer Environment: Ensure your 3D printer is in a stable environment, free from vibrations and direct sunlight.
3. Support Structure: BJD models often have large print sizes and weight. To ensure stability, it is necessary to use a sufficient support structure (adjust support tip diameter and central body diameter).
4. Build Plate Placement: If planning a full-size print, it is recommended to place an appropriately sized backplane at the bottom of the model before printing.
5. Printer Settings: Due to the high viscosity of TH-BJD resin (651-675 mPa.s), it is necessary to appropriately extend the retract wait time and light-off delay, and adjust the lift distance to ensure stable printing results. Refer to the "Printing Parameters Reference" section for detailed settings.

4. Operation

Follow these steps for optimal printing results with RESIONE TH-BJD Tough Resin.

4.1 Printing Parameters Reference

The following table provides recommended printing parameters for various printer brands. These are general guidelines; fine-tuning may be required for your specific printer model and environmental conditions. Always refer to your printer's factory standard resin parameters as a baseline.

4.2 Post-Processing

1. Support Removal: It is recommended to remove support structures from the printed object before washing.
2. Washing: Printed models can be quickly washed. If the resin liquid is difficult to wash off the surface, adjust the normal exposure time, extend the static time before printing, and increase the light-off delay and lift distance. The surface should not feel sticky after washing.
3. Post-Curing: After washing, cure the model using a 40W UV light source for 10 minutes on each side. For articulated models, focus on curing the joints during the post-curing stage to ensure ideal strength and functionality.
4. Color Stability: If the printed object yellows during the post-curing process, place it in a ventilated area for 48-96 hours to gradually restore its original color.

5. Maintenance

Proper maintenance ensures the longevity of your printed objects and resin.

• Storage of Printed Objects: Store printed objects in a cool, ventilated place. In high-humidity environments, consider coating the surface of printed objects with paint to enhance moisture resistance.
• Transportation of Printed Objects: To ensure safe transportation, wrap printed objects with foam and use sealed packaging. For hollow printed objects, ensure they are thoroughly cleaned and completely cured before packaging and shipping to prevent residual resin from affecting the object.
• Resin Container Cleaning: After use, clean the resin vat and build plate thoroughly with IPA or a suitable resin cleaner.

6. Troubleshooting

This section addresses common issues encountered during 3D printing with RESIONE TH-BJD Tough Resin.

• Prints Not Sticking to Build Plate:
  • Ensure the build plate is properly leveled and clean.
  • Increase bottom exposure time.
  • Verify ambient temperature is within the recommended range (25-35°C).
• Print Failures / Delamination:
  • Check exposure times and adjust if necessary (refer to printing parameters table).
  • Increase light-off delay to allow resin to settle.
  • Ensure the resin is well-mixed before printing.
  • Inspect the FEP film for damage or cloudiness.
• Models Yellowing After Curing:
  • This can sometimes occur. Place the yellowed object in a ventilated area for 48-96 hours; the color should gradually return to normal.
• Difficulty Removing Supports:
  • Consider using a heat gun to slightly soften the supports before removal, as suggested by user reviews.
  • Adjust support settings in your slicer software (e.g., use spherical contact points).
• Resin Viscosity Issues (too thick):
  • Ensure the resin is warmed to the recommended temperature before use.
  • Increase light-off delay to compensate for slower flow.
