1,Quantity and Size The set includes 10 sheets of 3D scanning markers, with each sheet containing 20 markers, totaling 200 markers, with 12mm inner diameter and 19mm outer diameter.2,High Performance These 3D scanning dots have high reflectivity, tear resistant, water proof, sunlight resistant, with high ink absorption and and repeatable adhesion.3,Working Principle Use bright reflective film to adhere a layer of reflective glass microspheres on PET film by aluminum plating, and print hollow circular reflective dots according to specific sizes through screen printing.4,User Friendly Featuring a sticky foil design, these markers are easy to apply and remove, providing accurate data for 3D scanning, reverse engineering, metrology, and inspection applications.5,Wide Application The positioning markers are suitable for 3D scanner in the field of motion information collection, such as 3D motion capturing and gait analysis. The markers reflect the light emitted by the equipment usually infrared, which is then received by the data equipment for processing, enabling precise data acquisition.6,Versatile Usage These 3D scanning markers are suitable for industries such as automotive, aerospace, machinery, manufacturing, power generation, electronics, and education, aiding in various scanning and tracking processes. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
