2. Resin Selection & Post-Processing (Crucial)

Compatible resins: Siraya Tech Fast, Build, Blu, Easy, or Sculpt resins, as they require no additional coating.Β 

Required Post-Processing Steps:

  • Clean: Wash your print with 90%+ IPA or Ethanol. Use an ultrasonic bath for 5 minutes or a brush to ensure all uncured resin is removed.

  • Dry: Use a hairdryer to dry the print completely.

  • Water-Submerged Curing: Fully submerge the print in a clean bucket of water.

    • Standard Models: Cure for 30 minutes under a UV light fixture while submerged.

    • Complex Models: For deep recesses, replace the water and cure for an additional 30 minutes.

    • Note: Do not use sunlight for this step.

  • Final Dry: Bake the print in a low-heat oven at 45Β°C for 10 minutes.

3. Step-by-Step Instructions

Defiant 10 uses a 1:1 mixing ratio by weight.

  • Preparation: Use clean glass containers to avoid curing inhibition.

  • Pre-mix: Stir Part A and Part B individually in their original bottles before use.

  • Measure: Use a scale and the tare function to pour equal weights of Part A and Part B.

  • Mix: Stir thoroughly, making sure to scrape the walls and bottom of the container.

  • Degas (Recommended): Although it releases bubbles quickly, vacuum degassing is recommended for best results, especially below 20Β°C.

  • Pour: The silicone is now ready for mold making.

5. Troubleshooting

Silicone remains tacky or liquid near the print surface: This is a classic sign of silicone poisoning. Ensure you followed the water-submerged curing step precisely for 30–60 minutes.

Localized uncured spots: Often caused by residual resin in deep recesses. For complex models, increase the water-curing time and ensure all IPA has evaporated before pouring silicone.

Silicone cures too slowly: Please check your ambient temperature; Defiant 10 requires an indoor environment above 20Β°C for optimal curing speed.

Incomplete cure throughout the mold: Ensure Part A and Part B were mixed at a strict 1:1 weight ratio and stirred thoroughly, scraping the sides and bottom.

Bubbles in the final mold: While the formula releases bubbles quickly, you may need to degas using a vacuum chamber if working in temperatures below 20Β°C.

3rd party resins compatibility is not guaranteed: We cannot guarantee results with non-Siraya Tech resins. If poisoning occurs with other brands, try applying a specialized primer coating or switch to Siraya Tech Fast, Build, Blu, Easy, or Sculpt.
