The Raptor, Otter, and Ferret series currently do not support blue laser marker-free scanning. Support for Sermoon X1 is under development and will be available soon.
¶ Supported Device & Environment
Currently only supported with a USB wired connection using the Sermoon S1 and Sermoon P1 scanners. Preparations before use:
- For Sermoon S1: Update the device firmware to v1.1.2 or later.
- For Sermoon P1: Update the device firmware to v1.0.47 or later.
- Perform calibration before first use.
- Update CrealityScan to v4.2.2 or later.

¶ How to Use
¶ Scan Settings
- Only Cross lines Laser Mode is supported
- Fast fusion is not yet available after scanning (will be added in a future version)

¶ Resolution Recommendations
The current Blue Laser marker-free scanning feature is more focused on improving the scanning experience and smoothness. The official recommended resolution settings are as follows:
- Real-time Resolution: ≥ 0.2 mm

- Fusion Resolution: ≥ 0.2 mm

If you need a smaller resolution, we still recommend using the "with marker" mode along with markers.
¶ Scanning Tips
- Under the marker-free scanning mode, it is recommended to move the scanner slowly to avoid losing tracking. If tracking is lost, move the scanner back to an area with clear geometric features; tracking will resume and you can continue scanning.
- For long sessions, use the lanyard to prevent accidental drops.
¶ Performance
¶ Frame Rate
- Maximum frame rate in marker-free mode: 30 fps; stable frame rate: 23–28 fps
¶ Processing Time
- Fusion: Faster than infrared mode, slightly slower than traditional Blue Laser mode with markers
- Meshing: Similar to Blue Laser mode with markers
- Color Mapping: Similar to infrared mode
- Deleting scan data: Slower than both Blue Laser mode with markers and infrared mode
¶ Resource Usage
- Memory usage: Higher than traditional Blue Laser mode with markers
- CPU usage: Approximately 100%
- Data size: Approximately 20%–30% larger than Blue Laser mode with markers
¶ Scan Quality
- Quality ranking: Blue Laser mode with markers ≈ Blue Laser mode markerless > infrared mode
- Laser knife marks (horizontal stripes/lines) may appear on the scanned model.
- Overexposure may occur in auto exposure mode
¶ Suitable Scenarios
¶ Recommended for
Medium to large objects
- Blue Laser mode with markers ≈ Blue Laser mode marker-free > infrared mode
Objects with strong texture features
¶ Limitations
Poor recognition on low‑texture surfaces. The following materials/surfaces may produce poor results:
- Highly reflective surfaces (e.g., mirrors)
- Black, light‑absorbing materials
- Glazed, slightly reflective materials
- Metals and other special materials
Not suitable for small objects
