A common mistake is overscanning, meaning scanning the same area multiple times.
This does not improve quality and can actually make digital reconstruction more difficult. Excess data may interfere with image alignment and introduce errors into the final model.
Many operators try to fix issues by rescanning the same area repeatedly, but this often worsens the result.
Another important factor is lighting.
Direct light, reflections, or poorly positioned lighting can interfere with data capture and reduce accuracy.
How to avoid it
Scan each area correctly once
Avoid unnecessary repetitions
Only rescan specific areas when needed
Control the lighting
Avoid direct reflections
Conclusion
Scanning more does not mean better results, and poor lighting can compromise accuracy.
