Tabletop 3D scanners are used for creating digital 3D models of physical objects. They are commonly employed in industries like product design, art preservation, and quality control, as well as by hobbyists for scanning collectibles or prototypes.

Tabletop 3D scanners typically use a combination of lasers, structured light, or photogrammetry techniques to capture the geometry of an object. The scanner projects light onto the object and captures the reflections to create a detailed 3D model.

Advantages include high precision and detail in scanning, ease of use, and the capability to quickly generate 3D models for various applications. They are often compact and designed for desktop use, making them accessible for small studios and individual users.

Generally, tabletop 3D scanners are designed for smaller objects due to their size constraints. However, some models may have interchangeable components or modular designs that allow for scanning larger items, though this may require additional setup or equipment.
