3D scanners generate 3D models of physical objects by capturing their surface geometry and texture. There are several common methods for 3D scanning, including laser triangulation, structured light scanning, photogrammetry, and laser pulse-based time-of-flight scanning. 3D scanners are used across industries like automotive and manufacturing to check part performance through 3D models, and in applications like industrial design, reverse engineering, and gaming. The cost of 3D scanners can range from around $100 for basic consumer scanners to over $800 for higher-end professional scanners.
