The cost of 3D scanning can range from $150 up to thousands of dollars. An object with a simple geometric shape would cost $150, while a large sculpture with intricate design can cost thousands of dollars or even more.

A 3D scanner works with structured light using the principles of triangulation. The sensor projects a precise shifting fringe pattern across the part's surface, and two cameras capture the surface geometry based on the pattern distortion, calculating 3D coordinate measurements.

3D scanning apps generally provide tips and guidance to help properly take the pictures. The app then processes these pictures and aligns them together to form a 3D model. The 3D model is then available for export or editing using additional 3D software.
