3D scanning

High-precision 3D scanning

With ATOS scanners from GOM, we can scan with an accuracy of 0.01 mm and a data density of 34 points per 1 mm. The scanning output is a 3D model consisting of a curvature-optimized polygonal mesh that can be exported to STL format.

 

Thanks to unique technologies such as vertical and horizontal projection, Triple Scan function, pixel merging, blue light equalizer or automatic glare detection, the resulting scanned data is highly accurate with minimal noise.

 

The scanner is mobile and can scan very small to medium-sized parts up to 2 m.

Dimensional inspection of the part

Comparison of scanned data with the nominal CAD model. We use the GOM Inspect Professional software, which is one of the absolute leaders in inspection software. The most commonly used comparison of 3D data is by means of a colour deviation map or inspection sections. Length or angle dimensions or geometric tolerances of shape and position can also be checked.

 

The output can be not only a clear PDF report with images, tables or graphs, but also data in Excel or the entire project for the free version of GOM Inspect.

Reverse engineering and 3D modelling

In reverse engineering, we convert scanned data (polygonal mesh) into a flat 3D model (CAD). A planar model is necessary when the scanned data is to be loaded into a CAD software (geometry modification). We use the ZEISS Reverse Engineering software, which has many tools to quickly model surfaces on a polygonal mesh.

 

The accuracy of the surface model to the original scan is checked with a color deviation map, and the smoothness of the surfaces is checked with a zebra map.

 

The output is a 3D model in IGES or STEP format.
