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, featuring an inner diameter of 12mm and an 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, offering strong adhesion to metal surfaces. In 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 simple to apply and remove thanks to their strong magnetic force. Durable and reliable, they can be reused multiple times, supporting consistent performance for 3D scanning and 3D printing applications. High Reflectivity for Accurate Scanning: Made from highly reflective materials, these 3D scanning points enhance reflectivity, improving scan registration accuracy. This helps capture fine details with greater precision, which is beneficial when using high-accuracy 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 as calibration tools and are useful in industrial and consumer-grade 3D scanning, reverse engineering, and inspection tasks. Color: As shown Material: Composite material Package Contents: 100 x 3D Magnetic Tracking Dot Note: Light reflection and differences in display screens may cause slight variations between the color of the item in the image and the actual product. Measurement allows an error of +/- 1-3 cm.
