A 3D scanner is used to enter into a computer three-dimensional models of finished bas-reliefs. The scanner works with models on any hard material - stone, wood, metal, plastic, glass. The scanning program creates a computer model in STL format that can be used in 3D modeling programs, such as 3DMax or ArtCAM.

The 3D scanner works according to the contact principle. A touch sensor measures the height (depth) of the model at each point of the grid with a touch probe. The grid spacing is set in the scanning program. The smaller is the grid step, the better is the quality of small details, but the work time is longer too.

A 3D scanner measures heights in millions of surface points. If you take a measurement at each point of the fine grid, then the scan time will be measured in days. In the SAUNO scanner, algorithms that accelerate work are  used. For example, the scanning step is automatically adjusted for even and uneven areas. The scanner program identifies areas of the surface with complex terrain and scans them more carefully than the flat areas.

The scanner program allows you to select areas with fine details on the scanned model and re-scan them with high accuracy.

The 3D-scanner can be installed on the Graphic-3KS or Graphic-3KP machines. In the 3D scanner, the level sensor of the engraving machine is used as a touch sensor. The level gauge probe must be replaced with a contact needle. The 3D scanner is controlled by the Engrave program.
