Ample Quantity with Perfect Size: The package includes 100 magnetic 3D scanning points stored in a convenient plastic box. These 3D scanner dots are designed for efficient scanning, with an inner diameter of 12mm and outer diameter of 19mm, providing ideal dimensions for capturing complex details. Material: This set of 3D magnetic tracking dots is made from soft magnetic material, ensuring strong adhesion to metal surfaces. Featuring a classic black and white design, these markers allow for quick identification and are compatible with 3D scanners and white light scanners. Easy to Reuse: These 3D magnetic tracking dots are easy to apply and remove thanks to their strong magnetic force. Durable and reliable, they can be used multiple times, supporting efficient 3D scanning for applications such as 3D printing. High Reflectivity for Accurate Scanning: Made from highly reflective materials, these 3D scanning points provide excellent reflectivity. This enhances scan registration accuracy, allowing even fine details to be captured with high precision, which is essential when using high-resolution 3D scanners. Wide Application: These 3D scanning dots are suitable not only for 3D printing but also for optical mapping, machine vision, and other fields. They work well with 3D scanning systems and serve as a valuable calibration tool. Their versatility makes them useful for both industrial and consumer-grade 3D scanning, reverse engineering, inspection, and more. Color: As Shown Material: Composite material Package Contents: 100 x 3D Magnetic Tracking Dot Note: Light reflection and different displays may cause slight variations in the color of the item compared to the picture. Measurement error allowance is +/- 1-3 cm.
