The 3D scan enables efficient and precise measurement of an existing component. A high-precision 3D scanner or an optical 3D coordinate measuring machine is used for this purpose, allowing components to be measured with an accuracy of up to ±10µm. During the measurement, up to 9 million data points are generated per image, so-called point clouds. These can be used to generate CAD data using intelligent software. Final details can be corrected using manual data post-processing.
Creation of CAD data from existing components
Customers often come to us and only have one original part in their hands. In some cases, the previous suppliers no longer exist, are unknown or the components are from a time before CAD – there are many reasons for this.
The aim in such cases is to rebuild the parts and bring them back to life. The first step is to measure them. Previously, the components were laboriously measured manually and CAD data was generated from this. However, this process is associated with a certain degree of imprecision, especially when it comes to more complex geometries.
With the 3D scanner, we can digitize even complex components efficiently and precisely within a very short time.
How 3D scanners work
An optical 3D scanner uses either LED light or a laser beam to aim at the measurement object and capture 3D data of the component by triangulation. The scanning methods include fringe projection and the light section method.
There are both stationary devices and flexible handheld scanners. Depending on requirements, mobile handheld scanners can be used so that the 3D scan can take place almost anywhere, or stationary scanners, which deliver the highest possible measurement accuracy. 3D scanners not only generate 3D data, they also enable subsequent analysis, including shape tolerances, positional tolerances and comparisons with CAD data. For example, we compare initial samples with the CAD data and visualize the differences as required.
We usually carry out 3D scans and material analyses free of charge for our customers, provided there is a realistic chance of obtaining the associated order for series production.
In order to provide our customers with the best possible support, our engineering office is equipped with a 3D scanner, 3D printer, a high-resolution digital microscope and a material analysis device for plastics. The 3D scan provides us with the geometry and the material analysis tells us the material of the existing component, if this is not known.

Quality assurance with the help of 3D scans
In addition to tracing components back to digital data records (reverse engineering, scan-to-CAD), we also use our optical scanner for quality assurance. This allows initial samples and series parts to be efficiently and precisely compared with CAD data and analyzed. Differences can be quickly identified, measured and documented in this way.
Our advanced 3D scanner captures every single detail of our products and enables a comprehensive analysis that goes far beyond conventional measuring methods. This not only speeds up the quality inspection process, but also enables us to identify and rectify faults at an early stage. With powerful scanning technology at your side, you can be confident of receiving products of the highest quality.
In addition, our 3D colour imaging provides a quick overview of deviations from the CAD model, allowing you to visualize and analyse with precision. Rely on innovative technology to ensure the highest standards of product quality.
If required, several series parts can also be measured simultaneously in batch mode and compared with a master model.
Just contact us – we will be happy to be your reliable partner and digitize, measure, analyse and optimize your components as an engineering office with around 30 years of experience. We specialize in finding economical solutions and bringing components into series production.
