2. Resin Vat Compatibility & Recharge Times
| 3D Printer Model | Compatible Resin Vat | Recharge Time |
|---|---|---|
| B9 Core 530 / 550 | DuraVat | 20 minutes per 1+ hour of use |
| Core 5 Series XL – 405 / Jewelry XL – 405 | FAST™Vat I / IV | No recharge time needed |
3. Resin Handling
-
Thoroughly mix FastWax before each use to ensure consistency and accuracy in prints.
-
For Core 5 Series XL – 405 users: After pouring resin into the FAST™Vat I, allow time for air bubbles to dissipate before printing.
-
Always fill the vat to the Max Fill line. Refer to the updated article: FastVat II & FastVat IV-Instructions for Use (IFU)
4. Pre-Print Procedure
Model Orientation
-
Orient parts as low to the build table as possible to minimize flaking caused by prolonged print times.
-
Avoid vertical orientation for tall prints; angle for optimal support and quality.
Support Strategy
-
FastWax is softer than Emerald or Yellow resins and requires more robust supports:
-
Use thicker supports, especially where multiple features join (e.g., ring shanks).
-
Add angled supports to minimize side-to-side movement during printing.
-
Support Examples

5. Post-Processing Procedure
Cleaning
-
Clean using B9Clean and new or lightly used IPA until all uncured resin is removed.
-
Do not cure the part while wet. Wait 30–60 minutes for IPA to evaporate completely to avoid white scarring or discoloration.
Curing Times
| Model Size | Model Cure (x2 Cycles) | Model Cure XL | Intensity | Duty Cycle |
|---|---|---|---|---|
| Tiny (<10x10x10 mm) | 2x 3 min (2 min rest) | 6 min | 3 | 10 |
| Small (10–20 mm) | 2x 5 min (2 min rest) | 10 min | 3 | 10 |
| Medium (20–40 mm) | 2x 6 min (2 min rest) | 12 min | 3 | 10 |
| Large (40–70 mm) | 2x 7 min (2 min rest) | 15 min | 3 | 10 |
If a part is not fully cured, repeat the cycle. Do not overexpose initially.
6. Performance Tips
