Ample Quantity with Perfect Size: The package includes 200 magnetic 3D scanning points stored in a convenient plastic box. These 3D scanner dots are designed for efficient scanning, with an inner diameter of 6mm and outer diameter of 10mm, offering ideal dimensions for capturing detailed surface geometry. Material: This set of 3D magnetic tracking dots is made from soft magnetic material with a durable reflective surface. The black and white design allows for easy identification and high contrast, making them compatible with various 3D scanners and structured light scanning systems. Easy to Reuse: Featuring strong magnetic adhesion, these tracking dots can be easily attached to and removed from metal surfaces. Their durable construction supports multiple uses, making them suitable for repeated 3D scanning applications, including 3D printing preparation and model alignment. High Reflectivity for Accurate Scanning: The scanning points are made with highly reflective materials that enhance signal return during scanning. This improves scan data registration accuracy and helps capture fine details with greater precision, supporting reliable results across various scanning conditions. Wide Application: These 3D scanning dots are suitable for use in 3D scanning, reverse engineering, industrial inspection, machine vision, and optical measurement systems. They serve as effective reference markers for both consumer-grade and professional 3D scanning workflows. Color: As shown Material: Plastic with reflective coating Package Contents: 200 pcs x 3D Magnetic Tracking Dot Note: Light reflection and display settings may cause slight color variations between the image and the actual item. Measurement error allowance is +/- 1-3 cm.
