3D measurement of components: 0.05 to 0.01 mm accurate data
How does the 3D measurement of components with a laser scanner work, how accurate is it and what kind of data do I get? We would like to answer these and other questions about the 3D measurement of components of all kinds in advance.
3D measurement of components is carried out via laser scanning or optical detection using a stripe light scanner. The result is a set of scanning points that together form a point cloud. As we work exclusively with 3D scanners from the industrial sector, we achieve an accuracy of 0.05 mm or, on request, an accuracy of 0.01 mm, depending on requirements. Noise and errors are eliminated and the resulting point cloud is then converted into an STL data model (polygonization).
Non-contact measurement of components in 3D
We work with the latest generation of 3D scanners from the industrial sector. While 3D scanners from the early days of this technology still required targets (reference points), which were laborious and time-consuming to stick onto the components, this is no longer necessary today. The 3D scanners we use allow us to dispense with such targets. This saves time and even increases accuracy. The non-contact measurement of the components in 3D means that the component is measured in 3D in a particularly gentle way. This type of 3D measurement is also particularly suitable for individual parts such as industrial prototypes, initial samples and older parts for which no drawings are available.
We mostly measure components from the following areas:
- Design / Development
- Model making / mold making
- Automotive industry
- Mechanical engineering / special machine construction
- Medicine
- Aerospace industry
The data obtained by 3D scanning is the starting point for various further processing steps.
- Direct 3D milling based on STL data
- Basis for 3D printing
- Size scaling, mirroring, multiplication etc.
- Target-actual comparisons with CAD data (target data):
CAD import, alignments, CAD comparison, CAD-based generation of control geometries, inspection functions, report generation - Technical drawings
Every customer who requires a 3D measurement of components has different priorities. The majority of our customers only require the 3D file, usually in STL format, in order to be able to carry out TARGET – ACTUAL comparisons or reverse engineering themselves. However, this work can of course also be commissioned from us. The possibilities after a 3D measurement are extremely varied, including the creation of a technical drawing based on the 3D scan data or even a change to the design. Simply tell us what you need.
Where are measurements taken in 3D?
As a rule, you send us the components and we carry out the 3D scan at our premises. For components that are too large for shipping or where shipping is not possible for other reasons, we will come to you.
How large can components be for 3D measurement?
We measure components ranging in size from around 1 centimeter to several meters. For components several meters in size, we usually come directly to you on site.

Here you can see a fuse holder next to the reconstructed component, which was scanned with a Structur light scanner with an accuracy of 0.05 mm. The component was reconstructed, adapted to the customer’s requirements and exported as a STEP and STL file. The models were 3D printed. In the background is an excerpt from the Miscolor comparison report showing the overlay of the 3D scan and the reconstructed part.
We scanned the hand switch produced for one of our customers in order to check the component for deviations in the production process. The scan was carried out with a high accuracy of 0.05 mm and has a tolerance of max. 0.59 mm to the original CAD model. The inspection showed that the production line works very well and no further adjustments need to be made. CAD file on the left, scanned model on the right. In the background you can see the alignment of these parts.

Here we show you the 3D measurement of a component after scanning and after reverse engineering in direct comparison. Depending on your requirements, you can also order this from us.
We measure components of all types and sizes in 3D. Here is an example of a cell phone cover.
