- 3D digitisation: complete acquisition of the component and preparation of a 3D model of the surface of the component
- Data pool: output of the data as triangulated surface model (STL data)
- Maximum precision: 3D scans with a resolution of up to 0.035 mm
- Data density: up to 12 million measurement points are acquired during a scan
- Measuring volume: flexible measuring volume for different component sizes and accuracies
- Measurement in your production: our 3D scanners are suitable for mobile use
- Mobile ESD protection zone for the inspection of components sensitive to electrostatic
- Training: we train our customers so they can undertake 3D scans and evaluate the data independently
How does the 3d scan work?
A 3D scanner is a stereo camera system with two cameras that view a specific area of the component at the same time. Between the objectives there is a projector that projects a structured light pattern onto the object. In this way recesses and edges can be detected and depicted in images. The coordinates of all image points that appear in both images at the same time are calculated and output in a 3D point cloud. The individual images are linked together with the aid of control points. In this way the 3D model of the component is produced.
Flexible selection of measuring systems and measuring volumes exactly tailored to your component
Shortest measuring time for a very high point density (12 million points per individual measurement)
Measurement from various perspectives for holistic component digitisation
Realtime transformation of the individual measurements into a point cloud
Conversion of the point cloud to polygons
The result: a 3d model (stl model) of all the external geometries that can be reached
On site in your facility:
Our 3d scanners in mobile use
If you cannot come to us, we will come to you. Using our mobile 3D scanners, we acquire your components directly on site in your facility, irrespective of whether a single sample or during ongoing series production. Thanks to our mobile turntable, even the semi-automatic acquisition of your measurement objects is not a problem.
Do you want to acquire your components yourself using your equipment? Then we will train and support you specifically in the acquisition and evaluation of your components.
Technical equipment
Our highly precise scanners manufactured by Carl Zeiss GOM Metrology are available for 3D scanning. Using our ATOS Q (8 MP) we acquire measuring volumes from 100 × 70 × 60 mm to 500 × 370 × 320 mm. Our ATOS 5 (12 MP) can even acquire measuring volumes up to 1000 × 750 × 750 mm.
The measuring volume can be composed, in this way we can cover a component spectrum from a few millimetres up to 3 m.
Thanks to our rotating-swivelling units, semi-automatic measurement is possible without problems. By means of different objectives, the resolution and the size of the measuring volume can be matched exactly to your components.
Almost all our measuring equipment for 3D scans is also suitable for mobile use. As such we can also prepare your 3D scans on site in your facility.

Evaluation of your 3d data
For the analysis and individual evaluation of the 3D data we utilise ZEISS Inspect Pro. This software application bundles together all the necessary steps for an efficient inspection sequence - from the acquisition of the component to be inspected, through mesh processing, CAD import, the required measurements and analyses, e.g. statistical trend analyses, shape and position calculations, to surface comparisons, even digital assembly based on the 3D data analysed is not a problem.

Frequently asked questions about 3d scanning
How precise is a 3d scan?
Nowadays, 3D scanners achieve resolutions of up to 0.035 mm and acquire up to 12 million measurement points during each scan. The precision of modern 3D scanners is therefore very high, but is not quite as high as that of tactile measuring instruments. However, optical metrology shines with an incomparable data density acquired in the shortest possible time.
Which surfaces are suitable for 3d scanning?
The use of a scanning spray is recommended for transparent or strongly reflecting surfaces. This spray gives the surface a matt finish and makes it easy for the 3D scanner to detect the surface. Here there is a choice of permanent and sublimating scanning sprays from which you can select the most suitable depending on the surface material and purpose.
What advantages does a 3d scan offer over tactile measurement and ct?
Unlike computed tomography, 3D scanning technology is able to digitise almost all materials - independent of their density. Components that are too large for a CT can also be acquired using a 3D scanner.
Unlike tactile measurement, during a 3D scan a complete image of the surface is produced, in practice therefore a complete three-dimensional model of the component. As such deviations can be clearly depicted graphically. Do you need an evaluation of the surface geometry acquired on the STL data? With a 3D scan this action is possible at any time without renewed measurement.
Due to their compactness, our 3D scanners can be used on site in your facility.
