The following is the correct operation procedure and precautions for using a 3D foot scanner:
1. Preparation Before Operation
Connect the power supply and connect to the computer.
Keep the scanning area floor flat, avoiding strong direct light that may affect laser accuracy.
User Preparation:
Remove shoes and socks, roll up pants to mid-calf to ensure the feet are fully exposed; it is recommended to wear light-colored socks or go barefoot (dark or patterned socks require device parameter adjustment).
When measuring children, assist in adjusting standing posture to avoid toes turning inward or outward.
2. Scanning Process
Standard Standing Posture:
Align both heels with the red line, naturally separate feet shoulder-width apart, and evenly distribute body weight.
Maintain upright and relaxed posture; do not move the body or feet during scanning (takes about 5–10 seconds).
Software Operation Guide:
Start the scanning software and follow voice prompts (e.g., “Please select the heel point”).
3. Data Processing and Application
Report Generation and Interpretation:
After scanning, a 3D model and digital report are automatically generated, including arch type (flat foot/high arch), pronation/supination angles, shoe size recommendations, etc.
Focus on key indicators such as footprint coefficient (0.21–0.26 is normal range), heel tilt angle, etc.
Data Export and Customization Connection:
Export STL format models, which can be directly used for 3D printing corrective insoles or custom footwear.
Supports WeChat report pushing for easy user archiving or forwarding to medical/shoe-making institutions.
4. Precautions
Accuracy Assurance: Medical-grade devices (accuracy ±0.5mm) require regular laser source calibration; consumer-grade devices should avoid use in humid environments.
Abnormal Handling: If marker point recognition fails (e.g., heel point is blurry), manual point selection and re-measurement are required.
Applicable Population: Children and postoperative patients should preferably use non-contact scanning (laser/structured light technology) to avoid foot pressure.
Note: Functional flat foot (e.g., arch disappears when standing) is recommended to be evaluated with dynamic scanning, as traditional static measurement may miss diagnosis.
