FastWax Instructions for Use - UPDATED 6/2025

FastWax is a high-performance resin optimized for fine-detailed parts, smooth surface finishes, and superior burnout characteristics. These instructions are designed to help users get the best results from FastWax on compatible B9Creations 3D printer

1. Printer Compatibility & Settings

FastWax is compatible with the following B9 Core Series models:

  • B9 Core 530

  • B9 Core 550

  • B9 Core 5 Series XL – 405

  • B9 Core Jewelry Edition XL – 405

Print Resolution

  • All supported models print at 50µm resolution using FastWax.


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

  • Yellow or Emerald Support Example

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

Recommended Applications

  • Ideal for:

    • Sharp, detailed parts (e.g., engraved lettering)

    • Fine jewelry components

    • Smooth curved or flat surfaces

Orientation Optimization

  • For tall parts: Orient at an angle, not vertically, to reduce flaking and ensure structural stability.

Example Results

  • Sharp, straight-edged parts 

  • Small, fine-detailed parts 

  • Large, smooth-surfaced parts
